Venoarterial extracorporeal membrane oxygenation (VA ECMO) is a form of temporary mechanical circulatory support and simultaneous extracorporeal gas exchange for acute cardiorespiratory failure, including refractory cardiogenic shock (CS) and cardiac arrest (CA). Few studies have assessed predictors of successful weaning (SW) from VA ECMO. This systematic review and meta-analysis aimed to identify a multiparameter strategy associated with SW from VA ECMO. PubMed and the Cochrane Library and the International Clinical Trials Registry Platform were searched. Studies reporting adult patients with CS or CA treated with VA ECMO published from the year 2000 onwards were included. Primary outcomes were hemodynamic, laboratory, and echocardiography parameters associated with a VA ECMO SW. A total of 11 studies (n=653) were included in this review. Pooled VA ECMO SW was 45% (95%CI: 39–50%, I2 7%) and in-hospital mortality rate was 46.6% (95%CI: 33–60%; I2 36%). In the SW group, pulse pressure [MD 12.7 (95%CI: 7.3–18) I2 = 0%] and mean blood pressure [MD 20.15 (95%CI: 13.8–26.4 I2 = 0) were higher. They also had lower values of creatinine [MD –0.59 (95%CI: –0.9 to –0.2) I2 = 7%], lactate [MD –3.1 (95%CI: –5.4 to –0.7) I2 = 89%], and creatine kinase [–2779.5 (95%CI: –5387 to –171) I2 = 38%]. And higher left and right ventricular ejection fraction, MD 17.9% (95%CI: –0.2–36.2) I2 = 91%, and MD 15.9% (95%CI 11.9–20) I2 = 0%, respectively. Different hemodynamic, laboratory, and echocardiographic parameters were associated with successful device removal. This systematic review demonstrated the relationship of multiparametric assessment on VA ECMO SW.

p. 12
Molli Kiran, Shrinivas Gadhinglajkar, Rupa Sreedhar, Subin Sukesan, Vivek Pillai, Varghese Panicker
DOI
:10.4103/aca.aca_287_20
Background:
Transesophageal echocardiography (TEE) probe insertion may be associated with many complications. Demographic factors and airway conditions such as high Mallampati scores (MMC) and Cormack-Lehane grades (MCLG) are likely to have an impact on its ease of insertion. The primary aim of this study was to identify the predictive factors for difficult real-time-three-dimensional TEE probe insertion.
Methods:
A total of 153 adult patients undergoing cardiac surgery were prospectively evaluated. The upper airway manipulations required for TEE probe placement were jaw thrust, reverse Sellick's maneuver, and laryngoscopy. All the patients who required airway manipulations were grouped under difficult TEE probe placement group. We evaluated the patients' predictive factors such as demographic characteristics and factors related to difficult intubation.
Results:
Out of 153 patients, 123 were males and 30 were females. Overall, 27.5% (
n
= 42) patients had difficulty in probe placement. About 31.7% (
n
= 39) males had difficulty in TEE probe placement against 13% (
n
= 4) females (
P
-value 0.045). Difficulty in TEE probe placement was found in 72.7% (
n
= 16) of obese patients (body mass index [BMI] > 30), compared to 18.6% (
n
= 17) in the patients with BMI less than 25 (
P
-value < 0.001). Probe insertion was significantly more difficult in the presence of MMC III and IV (50%,
n
= 18) compared to class I (19.2%,
n
= 10) (
P
-value 0.001) and MCLG III (73.3%,
n
= 22) compared to grade I (11.1%,
n
= 7) (
P
-value 0.001).
Conclusion:
Male gender, obesity, higher grades of MMC and MCLG were found to be the risk factors for difficult TEE probe placement in anesthetized patients.

p. 17
Michopanou Nektaria, Stavros Theologou, Charitos Christos, Saroglou George, Eltheni Rokeia, Savvas Dimitrios, Pavlopoulou Ioanna
DOI
:10.4103/aca.aca_290_20
Background:
Myxomas are the most common primary cardiac tumors that develop mostly at the atrial chambers of the heart and represent 0,25% of all cardiac diseases.
Methods:
This is a retrospective study aiming to analyze epidemiological and intraoperative data from cardiac myxoma cases in the hospital of the last 32 years. The study population was 145 cardiac surgical patients and was divided into 4 certain 8-year periods. 87,6% of cases had the myxoma located at left atrium and 97,2% of all patients fully recovered. 4,1% of patients relapsed and underwent a redo operation.
Results:
Mean CPB time and mean ICU length of stay increased during the 8-year periods (
p
< 0,001,
P
< 0,001,
P
= 0,002 and
P
= 0,003 respectively). In-hospital length of stay decreased to 5 days in the most recent period (
p
< 0,001). Cases significantly increased to 54 in the last 8-year period (
p
= 0,009).
Conclusion:
Improvement on cardiac imaging and a better accessibility may drive patients to earlier and safer diagnosis of myxomas preventing any deterioration of their condition. Improvement on postoperative care can also reduce in-hospital length of stay. Surgical excision is the treatment of choice and guaranteed survival at 97,2% of patients.

Introduction:
No mortality risk prediction model has previously been validated for cardiac surgery in Indonesia. This study aimed at validating the EuroSCORE II and Age Creatinine Ejection Fraction (ACEF) score as predictors for in-hospital mortality after cardiac surgery a in tertiary center, and if necessary, to recalibrate the EuroSCORE II model to our population.
Methods:
This study was a single-center observational study from prospectively collected data on adult patients undergoing cardiac surgery from January 2006 to December 2011 (
n
= 1833). EuroSCORE II and ACEF scores were calculated for all patients to predict in-hospital mortality. Discrimination was assessed using the area under the curve (AUC) with a 95% confidence interval. Calibration was assessed with the Hosmer–Lemeshow test (HL test). Multivariable analysis was performed to recalibrate the EuroSCORE II; variables with
P
< 0.2 entered the final model.
Results:
The in-hospital mortality rate was 3.8%, which was underestimated by the EuroSCORE II (2.1%) and the ACEF score (2.4%). EuroSCORE II (AUC 0.774 (0.714–0.834)) showed good discrimination, whereas the ACEF score (AUC 0.638 [0.561–0.718]) showed poor discrimination. The differences in AUC were significant (
P
= 0.002). Both scores were poorly calibrated (EuroSCORE II: HL test
P
< 0.001, ACEF score: HL test
P
< 0.001) and underestimated mortality in all risk groups. After recalibration, EuroSCORE II showed good discrimination (AUC 0.776 [0.714– 0.840]) and calibration (HL test
P
= 0.79).
Conclusions:
EuroSCORE II and the ACEF score were unsuitable for risk prediction of in-hospital mortality after cardiac surgery in our center. Following recalibration, the calibration of the EuroSCORE II was greatly improved.

DOI
:10.4103/aca.aca_311_20
Background:
General anesthesia has traditionally been used in transcatheter aortic valve replacement; however, there has been increasing interest and momentum in alternative anesthetic techniques.
Aims:
To perform a descriptive study of anesthetic management options in transcatheter aortic valve replacements in the United States, comparing trends in use of monitored anesthesia care versus general anesthesia.
Settings and Design:
Data evaluated from the American Society of Anesthesiologists' (ASA) Anesthesia Quality Institute's National Anesthesia Clinical Outcomes Registry.
Materials and Methods:
Multivariable logistic regression was used to identify predictors associated with use of monitored anesthesia care compared to general anesthesia.
Results:
The use of monitored anesthesia care has increased from 1.8% of cases in 2013 to 25.2% in 2017 (
p
= 0.0001). Patients were more likely ages 80+ (66% vs. 61%;
p
= 0.0001), male (54% vs. 52%;
p
= 0.0001), ASA physical status > III (86% vs. 80%;
p
= 0.0001), cared for in the Northeast (38% vs. 22%;
p
= 0.0001), and residents in zip codes with higher median income ($63,382 vs. $55,311;
p
= 0.0001). Multivariable analysis revealed each one-year increase in age, every 50 procedures performed annually at a practice, and being male were associated with 3% (
p
= 0.0001), 33% (
p
= 0.012), and 16% (
p
= 0.026) increased odds of monitored anesthesia care, respectively. Centers in the Northeast were more likely to use monitored anesthesia care (all
p
< 0.005). Patients who underwent approaches other than percutaneous femoral arterial were less likely to receive monitored anesthesia care (adjusted odds ratios all < 0.51; all
p
= 0.0001).
Conclusion:
Anesthetic type for transcatheter aortic valve replacements in the United States varies with age, sex, geography, volume of cases performed at a center, and procedural approach.

Use of methylene blue to treat vasoplegia syndrome in cystic fibrosis patients undergoing lung transplantation: A case series
p. 36
Gabriel C Washington, Christian T O'Donnell, Jai Madhok, Kiah M Williams, Charles C Hill
DOI
:10.4103/aca.aca_276_20
Background:
Several studies have demonstrated the utility of methylene blue (MB) to treat vasoplegic syndrome (VS), but some have cautioned against its routine use in lung transplantation with only two cases described in prominent literature. Cystic fibrosis patients commonly have chronic infections which predispose them to a systemic inflammatory syndrome-like vasoplegic response during lung transplantation. We present 13 cystic fibrosis patients who underwent lung transplantation and received MB for vasoplegic syndrome while on cardiopulmonary bypass, with or without inhaled pulmonary vasodilator therapy.
Methods:
Single-center, retrospective, case series analysis of cystic fibrosis patients who underwent lung transplant and received MB for vasoplegia. We defined the primary outcome as 30-day mortality, and secondary outcomes as primary graft failure, 1-year mortality, postoperative complications, and hemodynamic response to MB.
Results:
MB was associated with a significant increase in mean arterial pressure (MAP) (
P
< 0.001) in all patients, and 84.6% (11/13) of the patients had either a decrease or no change in vasopressor requirement. No patients developed acute primary graft dysfunction and there was 100% 30-day and 1-year survival. One patient required Extracorporeal membrane oxygenation (ECMO) for hypoxemia and 69% (9/13) of the patients had evidence of postoperative right ventricular dysfunction, but no patients required a right ventricular assist device.
Conclusion:
This case series demonstrates the effectiveness of MB in treating vasoplegia in cystic fibrosis patients during lung transplantation, without evidence of primary graft dysfunction, 30-day or 1-year mortality. The safety of MB regarding hypoxemia and increased pulmonary vascular resistance requires further investigation.

Elastic recoil signal on tissue doppler imaging of mitral annulus as a qualitative test to identify left ventricular diastolic function
p. 42
Deepak Prakash Borde, Devarakonda Bhargava Venkata, Shreedhar Joshi, Amish Jasapara, Pooja Joshi, Balaji Asegaonkar
DOI
:10.4103/aca.aca_20_21
Introduction:
Left ventricular (LV) diastolic dysfunction is common on preoperative screening among patients undergoing surgery. There is no simple screening test at present to suspect LV diastolic dysfunction. This study was aimed to test the hypothesis, whether elastic recoil signal (ERS) on tissue Doppler imaging of mitral annulus (MA TDI) can be used as a qualitative test to differentiate patients from normal LV diastolic function versus patients with LV diastolic dysfunction.
Methods:
This was a prospective cross-sectional observational study of patients admitted for elective surgeries. Normal diastolic function and categorization of LV diastolic dysfunction into severity grades I, II, or III were performed as per the American Society of Echocardiography/ European Associationof Cardio Vascular Imaging (ASE/EACVI) recommendations for LV diastolic dysfunction.
Results:
There were 41 (61%) patients with normal LV diastolic function and 26 (39%) patients with various grades of LV diastolic dysfunction. In 38 out of 41 patients with normal LV diastolic function, the characteristic ERS was identified. The ERS was absent in all the patients with any grade of LV diastolic dysfunction. Consistency of identification of ERS on echocardiography was tested with a good interobserver variability coefficient of 0.94 (
P
-value <0.001). The presence of ERS demonstrated an excellent differentiation to rule out any LV diastolic dysfunction with an area under the receiver operating characteristics curve (AUROC) of 0.96 (CI 0.88–0.99;
P
value <0.001).
Conclusions:
To conclude, in a mixed surgical population, the anesthetist could successfully assess LV diastolic dysfunction in the preoperative period and the characteristic ERS on MA TDI signal can be used as a qualitative test to differentiate patients from normal LV diastolic function versus patients with LV diastolic dysfunction using the transthoracic echocardiography (TTE).

p. 50
KS Bharathi, Gegal Pruthi, Manasa Dhananjaya, Parimala Prasanna Simha
DOI
:10.4103/aca.aca_179_21
Background:
Right ventricular (RV) dysfunction is an important predictor of both immediate and long-term outcomes in valve surgeries. Levosimendan has proven beneficial in improving RV function.
Aims:
The objective was to study the effect of the addition of levosimendan to the conventional treatment on RV function in patients with RV dysfunction undergoing mitral valve (MV) surgeries.
Setting and Design:
Prospective randomized double-blinded controlled study at a tertiary care institution.
Materials and Methods:
Sixty adult patients aged 15–65 years, with preoperative transthoracic echocardiography (TTE) findings of RV dysfunction posted for elective MV surgery, were randomized into levosimendan (L) group and placebo (P) group. Patients in the L group were administered levosimendan at a rate of 0.1 mcg/kg/min after induction for 24 hrs, whereas patients in the
P
group were given multivitamin infusion at the same rate. Both the groups received standard inotropic therapy. The hemodynamic and echocardiographic parameters of RV function (RV size, Inferior vena cava (IVC) diameter, RV fractional area change (RVFAC) Tricuspid annular plane systolic excursion (TAPSE), and Systolic Pulmonary Artery Pressure (SPAP) were compared between the groups at 6 hrs, 24 hrs, and 7
th
day postoperatively.
Results:
All hemodynamic and echocardiographic parameters of RV function like RV size, IVC diameter, RVFAC, TAPSE, and SPAP improved from baseline to 24 hrs in both groups. Levosimendan caused a significant improvement in RV function compared to the
P
group at 24 hrs and 7
th
day postoperatively.
Conclusions:
The present study concludes that levosimendan is a promising option in patients with RV dysfunction undergoing MV surgeries.

Single value of NephroCheck™ performed at 4 hours after surgery does not predict acute kidney injury in off-pump coronary artery bypass surgery
p. 57
Muralidhar Kanchi, Karanam D Sudheshna, Srinath Damodaran, Vikneswaran Gunaseelan, Anup D Varghese, Kumar Belani
DOI
:10.4103/aca.aca_56_21
Background:
Quantification of urinary tissue inhibitor of metalloproteinase-2 (TIMP-2) and insulin-like growth factor binding protein (IFGBP-7), which is commercially known as NephroCheck™(NC) test have been suggested as promising tools for the early detection of acute kidney injury (AKI) after cardiac surgery involving cardio-pulmonary bypass (CPB).
Objectives:
The aim of the present study was to test the hypothesis that single value of postoperative NC test performed at 4 hours after surgery can predict AKI in off-pump coronary artery bypass grafting (OPCABG) surgery.
Setting and Design:
This prospective single-center study was conducted at the tertiary cardiac center in India from December 2017 to November 2018.
Methods:
Ninety adult patients of both sex undergoing elective OPCABG were included. Anesthesia was standardized to all patients. Urine samples were collected preoperatively and at 4 hours after surgery for NC test. Urine output, serum creatinine, estimated glomerular filtration rate (eGFR) were also measured. AKI staging was based on kidney disease improving global outcomes (KDIGO) guidelines.
Statistical Analysis:
To assess the predictability of NC test for the primary endpoint, area under the receiver operating characteristic curve (ROC), was calculated.
Results:
Thirteen patients developed AKI in the study cohort (14.4%) out of which 7 patients (7.8%) developed stage 2/3 AKI and the remaining stage 1 AKI. Baseline renal parameters were similar between AKI and non-AKI group. The area under curve (AUC) of NC test at 4 hours after surgery was 0.60 [95% confidence interval (CI): 0.42-0.77]. Postoperative NC test performed at 4 hours after surgery did not predict AKI in this study population (
P
= 0.24). There were no significant differences in duration of mechanical ventilation, length of intensive care stay and hospital stay between the two groups (
P
> 0.05).
Conclusion:
NephroCheck
™
test performed at 4 hours after surgery did not identify patients at risk for developing AKI following OPCABG surgery.

Comparison of glucose control by added liraglutide to only insulin infusion in diabetic patient undergoing cardiac surgery: A preliminary randomized-controlled trial
p. 63
Wacharin Sindhvananda, Weerasake Poopuangpairoj, Teerarat Jaiprasat, Pachara Ongcharit
DOI
:10.4103/aca.aca_214_20
Background:
Liraglutide, glucagon-like peptide-1 (GLP-1) receptor agonist, has been investigated for safety and effectiveness for blood glucose (BG) control in a surgical setting. However, there are only a few studies specific to cardiac surgery patients.
Aims:
To primarily compare perioperative 1) BG and 2) glycemic variability (GV) between added liraglutide and only insulin infusion in diabetes mellitus (DM) patients undergoing cardiac surgery.
Setting and Design:
A randomized control trial was conducted in DM patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). Inclusion criteria were age 20–80 years and DM Type 2.
Material and Methods
: The recruited patients were randomly assigned to Group 1 (added liraglutide with insulin infusion) and Group 2 (insulin infusion). Insulin infusion was based on institutional protocol. Point of care testing (POCT) glucose was used for the adjustment of insulin and BG analysis. Continuous glucose monitor (CGM) was for GV analysis (using Standard deviation: SD).
Statistics
: t-test, Chi-square or Fisher-exact test, or Mann–Whitney U test.
Results
: Finally, 60 patients were in our study (Group 1 = 32 vs Group 2 = 28). Perioperative mean BG levels of Group 1 were significantly lower than Group 2 with a mean difference of 15.9 mg/dL. Nine patients (18.7% vs 10.7%,
P
= 0.384) had BG of 60–70 with mean BGs (109.1 vs 147.9,
P
= 0.001) in the morning. Thirteen patients (9.4% vs 35.7%,
P
= 0.025) had BG >180 mg/dL at the 1
st
operative hour. SDs were increasing, but lower SD of Group 1 were observed at the postoperative period. Mean of SDs at postoperative day 2 were 23.65 vs 32.79 mg/dL,
P
= 0.018.
Conclusions
: Liraglutide added with insulin infusion can attenuate perioperative BG and is beneficial in the aspect of lowering GV together with BG at the postoperative period in DM patients. Liraglutide can be applied in cardiac surgery but a rearrangement of time and dosage should be further investigated.

Pre-procedural serum albumin concentration is associated with length of stay, discharge destination, and 90-day mortality in patients after transcatheter aortic valve replacement
p. 72
Najla Y Beydoun, Lyubov Tsytsikova, Haesun Han, Alberto Furzan, Andrew Weintraub, Fredrick Cobey, Sadeq A Quraishi
DOI
:10.4103/aca.aca_114_21
Background:
As visceral protein expression may influence outcomes in patients with cardiovascular disease, we investigated whether pre-procedural albumin concentration is associated with length of stay (LOS) and 90-day mortality after transcatheter aortic valve repair (TAVR).
Methods:
We retrospectively analyzed data from TAVR patients at our institution between January 2013 and December 2017. For all patients, baseline albumin concentration was assessed between one and four weeks before the procedure. To investigate the association between albumin concentration and outcomes, we performed regression analyses, controlling for Society of Thoracic Surgeons, New York Heart Association classification, and Kansas City Cardiomyopathy Questionnaire 12 scores.
Results:
Three hundred eighty patients were included in the analyses. Cox-proportional hazards regression showed that patients with albumin concentrations <3.5 g/dL were 80% more likely to have prolonged ICU LOS (HR 1.79; 95%CI 1.04–2.57,
P
= 0.03) and 70% more likely to have prolonged hospital LOS (HR 1.68; 95%CI 1.01-2.46,
P
= 0.04) compared to patients with albumin concentrations >3.5 g/dL. Logistic regression showed that patients with albumin concentrations <3.5 g/dL were four times more likely to not survive to 90 days (OR 3.94; 1.13–12.63,
P
= 0.03) after their TAVR compared to patients with albumin concentrations >3.5 g/dL.
Conclusion:
Our data suggest that patients with pre-procedural albumin concentrations <3.5 g/dL are at an increased risk of adverse outcomes after TAVR compared to patients with albumin concentrations ≥3.5 g/dL. Prospective studies are needed to determine whether risk stratification based on pre-procedural albumin can improve outcomes and whether targeted interventions can improve pre-procedural albumin concentrations in potential TAVR candidates.

Concomitant mitral and aortic valve stenosis in a patient with mitral annular calcification and porcelain aorta poses a unique problem to the surgical team. Transcatheter aortic and mitral valve replacements in native valves offer a viable option for such selected group of patients. We present the case of a 54-year-old male who presented with severe aortic stenosis (AS) and severe mitral stenosis (MS) but was deemed high risk for surgery owing to intense calcification of the aorta and mitral annular calcification, and successfully underwent transcatheter double native valve replacement.

Resisting arrest: Perioperative confirmation and management of an iatrogenic aortocoronary arteriovenous fistula after coronary artery bypass grafting for redo cardiac surgery
p. 83

DOI
:10.4103/aca.aca_310_20
Although rare, iatrogenic aortocoronary arteriovenous fistulae (ACAVF) occur when a coronary graft is mistakenly anastomosed to an epicardial vein rather than its intended arterial target. Patients may be asymptomatic, demonstrate angina, dyspnea, arrhythmias, syncope, or diminished exercise capacity, and may have wide pulse pressures with evidence of coronary steal. A thorough insight into the disordered anatomy is critical to safely manage a patient for redo cardiac surgery, especially when attempting to arrest the heart. We present a case for redo cardiac surgery of an iatrogenic ACAVF confirmed perioperatively with multiple modalities and its intraoperative management.

Difficult ventilation in a patient with a giant aortic aneurysm: A challenge for the anesthesiologist
p. 86
Mar Montane-Muntane, María Ascaso, Lorena Rivera-Vallejo, Ricard Navarro-Ripoll
DOI
:10.4103/aca.aca_309_20
Patients with Marfan syndrome present anatomic variations that may increase the risk of a difficult airway. Moreover, they can present large aortic aneurysms, which may cause extrinsic airway compression. Therefore, difficult ventilation during general anesthesia poses a challenge in that the anesthesiologist has to promptly make a crucial differential diagnosis. Multidisciplinary preoperative assessment and planning of the airway and ventilation management are of utmost importance in such uncommon and highly complex clinical cases. Fiberoptic bronchoscopy is probably a really useful tool in order to assess the severity and extent of the airway compression, both preoperatively and intraoperatively. We present a clinical case where difficult ventilation occurred immediately after the induction of general anesthesia.

Thrombocytopenia is a common condition that recognizes an infinite number of possible causes, especially in specific settings like the one covered in this case report: the postoperative period of cardiac surgery. We report a case of an old male with multiple comorbidities who underwent a coronary angioplasty procedure and aortic valve replacement. He showed severe thrombocytopenia in the postoperative days. Differential diagnosis required a big effort, also for the experts in the field. Our goal was to aggressively treat the patient with prednisolone, platelets, and intravenous immunoglobulins to maximize the prognosis. Our patient developed no complications and was discharged successfully.

Williams-Beuren syndrome is a rare genetic malformation with predilection for supravalvular aortic stenosis. Apart from cardiovascular malformation, hypocalcemia, developmental delay, and elfin facies, challenging airway make perioperative management more eventful. Association of infective endocarditis within the aortic arch and pseudoaneurysm formation is infrequent. We, hereby report a case of pseudoaneurysm formation and infective vegetation within the aortic arch in a patient with Williams syndrome and the role of transthoracic echocardiography in its perioperative management.

The use of ECPELLA in patients with severe lung disease may result in an unfavorable phenomenon of differential hypoxia. The simultaneous evaluation of three arterial blood samples from different arterial line (right radial artery, left radial artery, ECMO arterial line) in patients at risk of Harlequin syndrome (also called differential hypoxemia (DH)) can localize the “mixing cloud” along the aorta. Focusing the attention on the “mixing cloud” position instead of on isolated flows of Veno-Arterial Extracorporeal Membrane Oxygenation (VA ECMO) and Impella CP makes the decision making easier about how to modify MCSs flows according to the clinical context. Herein, we present two cases in which ECPELLA configuration was used to treat a cardiogenic shock condition and how the ECPELLA-induced hypoxia was managed.

Electroconvulsive therapy (ECT) is a safe and effective treatment for many psychiatric disorders. The passage of electrical current lead to hemodynamic alterations which may be detrimental to patients suffering from severe coronary artery disease. We describe perioperative anesthetic management of a patient having severe left main coronary artery stenosis (LMCAS) with severe triple vessel coronary artery disease (TVD).

Three different patients presented to our institution with right-sided infective endocarditis (IE). All three were found to have vegetation on the tricuspid valve. These patients were started on appropriate antimicrobial therapy according to their blood cultures sensitivities. Despite this management, the patients' clinical status did not improve solely on antimicrobials. Surgery was, therefore, indicated to remove the vegetations. Traditionally, the appropriate management would have been invasive surgery. However, these patients were subjected to a novel treatment in our institution for right-sided IE: percutaneous mechanical vegetation debulking with an AngioVac system. After this procedure, all three patients' clinical status improved drastically. This new less invasive approach seems to offer the same results as the traditional invasive surgery, with faster recovery time. More comparative studies are needed to confirm this idea.
