Reoperation and Mechanical Circulatory Support After Repair of Anomalous Origin of the Left Coronary Artery From the Pulmonary Artery: A Twenty-Year Experience

Effectiveness and Safety of Mitral Valve Plasty in Patients with an Anomalous Origin of the Coronary Artery from the Pulmonary Artery

The study aimed to determine the effectiveness and safety of anomalous coronary artery from pulmonary artery (ACAPA) patients with moderate or severe mitral valve regurgitation (MVR) receiving mitral valve plasty (MVP) concurrently. Consecutive ACAPA patients undergoing surgery between 2015 and 2021 were retrospectively included. Patients were divided into three groups: moderate MVR without MVP (non-MVP (moderate) N = 14), moderate MVR with MVP (MVP (moderate) N = 13), and severe MVR with MVP (MVP (severe) N = 13). The primary safety endpoint was in-hospital surgery-related complications. The primary effectiveness outcome was left ventricular ejection function (LVEF) and left ventricular end-diastolic diameter (LVEDD) z-score at 2- and 24-month follow-ups. Multivariable linear regression models were used to obtain the β coefficient. The median age of the included patients was 7.5 years (IQR 1.4-26.5). The in-hospital surgery-related complication rates were 7.1%, 15.4%, and 7.7% in non-MVP (moderate), MVP (moderate), and MVP (severe) groups, separately. At the 2-month follow-up, the non-MVP (moderate) group had a better LVEF and LVEDD z-score compared with the MVP (moderate) group (LVEF β = 9.22, 95%CI 1.09 to 17.35; LVEDD z-score β = -2.49, 95%CI -4.53 to -0.45). At the 24-month follow-up, the LVEF of all patients and the LVEDD z-score of 90% of patients in the three groups returned to normal. For ACAPA patients with moderate MVR, MVP was not necessary, especially for pediatric patients (age < 3 years) and patients with secondary MVR. Further studies for ACAPA patients with severe MVR are still needed.

Anomalous left coronary artery from the pulmonary artery: Outcomes and management of mitral valve

Objective

Use of concomitant mitral valve repair remains controversial in the anomalous left coronary artery from the pulmonary artery (ALCAPA) with mitral regurgitation (MR). This study aimed to evaluate postoperative mitral valve function and explore the indication for concomitant mitral valve repair.

Materials and methods

The medical records of 111 patients with ALCAPA and MR who underwent ALCAPA surgery between April 2006 and November 2020 were reviewed. The patients were categorized into three groups for comparison, namely, group I consisted of 38 patients with trivial or mild MR who underwent ALCAPA repair only; group II consisted of 37 patients with moderate or severe MR who similarly had only surgery of the ALCAPA performed; and group III consisted of 36 patients who had concomitant mitral valve repair for moderate or severe MR.

Result

Overall mortality was 7.2% (8 of 111). The mortality of group II (16.2%, 6 of 37) was higher than those of groups I (5.3%, 2 of 38) and III (0%, 0 of 36) (p = 0.027). All three patients who underwent mitral valve reintervention were in group II. At the last follow-up, none of the patients had more than moderate MR in group I. The percentage of patients with improved MR grade was 79.4% (27 of 34) in group III and 51.4% (19 of 37) in group II (p = 0.001). The multivariate logistic regression revealed that concomitant mitral valve repair (adjusted odds ratio = 4.492, 95% CI: 1.909–12.794; p < 0.001) was the major factor influencing MR grade improvement.

Conclusion

The long-term outcomes after ALCAPA repair were favorable. For mild MR, ALCAPA repair only can be performed. For moderate and severe MR, we suggest concomitant mitral valve repair.

Anomalous Origin of the Left Coronary Artery From the Pulmonary Artery: A Retrospective Multicenter Study

OBJECTIVES

We aimed to describe characteristics and operative outcomes from a multicenter cohort of infants who underwent repair of anomalous left coronary artery from the pulmonary artery. We also aimed to identify factors associated with major adverse cardiovascular events following anomalous left coronary artery from the pulmonary artery repair.

DESIGN

Retrospective chart review.

SETTING

Twenty-one tertiary-care referral centers.

PATIENTS

Infants less than 365 days old who underwent anomalous left coronary artery from the pulmonary artery repair.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Major adverse cardiovascular events were defined as the occurrence of postoperative extracorporeal membrane oxygenation, cardiopulmonary resuscitation, left ventricular assist device, heart transplantation, or operative mortality. Factors independently associated with major adverse cardiovascular events were identified using multivariable logistic regression analysis. We reviewed 177 infants (< 365 d old) who underwent anomalous left coronary artery from the pulmonary artery repair between January 2009 and March 2018. Major adverse cardiovascular events occurred in 36 patients (20%). Twenty-nine patients (16%) received extracorporeal membrane oxygenation, 14 (8%) received cardiopulmonary resuscitation, four (2%) underwent left ventricular assist device placement, two (1%) underwent heart transplantation, and six (3.4%) suffered operative mortality. In multivariable analysis, preoperative inotropic support (odds ratio, 3.5; 95% CI, 1.4-8.5), cardiopulmonary bypass duration greater than 150 minutes (odds ratio, 6.9 min; 95% CI, 2.9-16.7 min), and preoperative creatinine greater than 0.3 mg/dL (odds ratio, 2.4 mg/dL; 95% CI, 1.1-5.6 mg/dL) were independently associated with major adverse cardiovascular events. In patients with preoperative left ventricular end-diastolic diameter measurements available (n = 116), left ventricular end-diastolic diameter z score greater than 6 was also independently associated with major adverse cardiovascular events (odds ratio, 7.6; 95% CI, 2.0-28.6).

CONCLUSIONS

In this contemporary multicenter analysis, one in five children who underwent surgical repair of anomalous left coronary artery from the pulmonary artery experienced major adverse cardiovascular events. Preoperative characteristics such as inotropic support, creatinine, and left ventricular end-diastolic diameter z score should be considered when planning for potential postoperative complications.

Midterm Surgical Outcomes for ALCAPA Repair in Infants and Children

BACKGROUND

 Surgical correction of an anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) has been associated with excellent survival during recent years. The purpose of this study was to evaluate the effectiveness of reimplantation of the coronary artery and to investigate the recovery of postoperative cardiac and mitral valve (MV) function.

METHODS

 From 2005 to 2015, 80 patients who had ALCAPA received surgical correction. Among them, 49 were infants. The median patient age was 7.8 months. Operative strategies included reimplantation of the coronary artery in 71 patients, the Takeuchi procedure in another 7 patients, and coronary artery ligation in the remaining 2 patients.

RESULTS

 There were 11 hospital deaths and 2 late deaths. Six patients required intraoperative or postoperative mechanical circulatory support. A significant improvement in the ejection fraction (EF) and shortening fraction (SF) was present in all surviving patients at discharge, at a 3-month follow-up and at a 1-year follow-up. MV function improved gradually after surgical repair with no late secondary intervention.

CONCLUSIONS

 The repair of ALCAPA can be accomplished by establishment of a dual-coronary system, which offers an acceptable mortality rate and will rarely require a second surgery. Left ventricular (LV) recovery is a progressive process, especially for infants with impaired LV function. Concomitant MV annuloplasty is safe and reliable and can be performed as necessary in patients with moderate or severe mitral valve regurgitation.

Anomalous left coronary artery from pulmonary artery repair: Outcomes from the European Congenital Heart Surgeons Association Database

INTRODUCTION

We sought to determine the surgical outcomes of patients with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) enrolled in the European Congenital Heart Surgeons Association (ECHSA) database.

MATERIALS AND METHODS

From 1999 to 2019, 907 patients with ALCAPA underwent surgical repair and were included in the current study. The primary outcome was in-hospital mortality. Secondary outcomes included frequency and results of concomitant mitral valve surgery and postoperative mechanical circulatory support (MCS).

RESULTS

The overall in-hospital mortality was 6% (54/907) and was significantly higher in neonates (p = .01), patients with lower body surface area (BSA) (p = .01), and those requiring postoperative MCS (p = .001). Associated mitral valve surgery was performed in 144 patients (15.9%) and was associated with longer cardiopulmonary bypass (CPB) and aortic cross-clamp times (AOX) (p ≤ .0001) but was not significantly related to an increase in in-hospital mortality. Postoperative MCS was required in 66 patients (7.3%). These patients were younger (p ≤ .001), had a lower BSA (p ≤ .001), and required a longer CPB (p ≤ .001) and AOX time (p ≤ .001).

CONCLUSIONS

ALCAPA repair can be achieved successfully, and with low surgical risk. Concomitant mitral valve procedures can be performed without increasing operative mortality. The use of MCS remains a valuable option, especially in younger patients.

Anomalous left coronary artery from the pulmonary artery repair outcomes: Preoperative mitral regurgitation persists in the follow-up

OBJECTIVE

This study aims to present the midterm outcomes of surgical correction of the anomalous left coronary artery from the pulmonary artery (ALCAPA) with a focus on mitral regurgitation (MR).

METHODS

Medical records of 36 ALCAPA patients who underwent surgery in a single center were retrospectively reviewed.

RESULTS

There were one (2.7%) neonate, 19 (52.7%) infants, 15 (41.6%) children, and 1 (2.7%) adult patient operated. Coronary reimplantation, tube reconstruction, and coronary artery bypass surgery techniques were performed in 29 (80.5%), 6 (16.6%), and 1 (2.7%) patient, respectively. Sixteen (44.4%) patients had a low ejection fraction and 13 (36.1%) patients had at least moderate MR preoperatively. None of our patients underwent a concomitant mitral surgery during the initial repair. Three and two patients died in the early and late postoperative period, respectively. Two patients underwent reoperation due to MR and pulmonary stenosis, separately. Preoperative MR was the only factor associated with at least moderate MR at the final follow-up (p < .01) and the presence of preoperative moderate or over-moderate MR estimated at least moderate MR at the final follow-up with 100% sensitivity and 80% specificity.

CONCLUSION

Although the mitral valve was not repaired in the first operation, the reoperation rate is low. However, a moderate or higher preoperative MR predicted MR at the last follow-up. Performing annuloplasty in such patients can be a strategy to be researched.

Intermediate Outcomes After Repair of Anomalous Left Coronary Artery From the Pulmonary Artery

BACKGROUND

Multicenter studies on infants with anomalous left coronary artery from the pulmonary artery (ALCAPA) are lacking. We report the intermediate-term outcomes after ALCAPA repair in a multicenter cohort and identify risk factors for reintervention or death after discharge.

METHODS

We retrospectively reviewed infants under 1 year of age who underwent ALCAPA repair from January 2009 to March 2018 at 21 US centers. The primary composite outcome was freedom from reintervention or death after discharge. We used the Kaplan-Meier survival analysis to examine freedom from reintervention or death and the Cox proportional hazard analysis to identify risk factors for this composite outcome.

RESULTS

One hundred seventy-seven infants underwent ALCAPA repair; 170 (97%) survived to hospital discharge without transplantation. Twenty-three patients were lost to follow-up. The median duration of follow-up in the remaining 147 patients was 3.8 years (25%, 75%: 1.9 years, 6.0 years). Echocardiographic data were available at ∼3 years after discharge in 98 patients. Left ventricular function was normal in 96 patients (98%), whereas 26 patients (27%) had greater than mild mitral valve regurgitation. Sixteen patients (11%) underwent 20 reinterventions with 1 late death. Patients undergoing the Takeuchi procedure or atypical repairs (hazard ratio, 8.0; 95% confidence interval, 2.1-30.0) or with moderate or greater mitral regurgitation on discharge echocardiogram (hazard ratio, 3.4; 95% confidence interval, 1.2-9.1) were at increased risk for reintervention.

CONCLUSIONS

Intermediate-term outcomes after ALCAPA repair in infants are favorable. Persistent left ventricular dysfunction and reinterventions were uncommon, and mortality was rare. Patients who required atypical surgical repair or had moderate or greater mitral regurgitation at discharge warrant closer follow-up.

Characteristics and Surgical Outcomes of Patients With Late Presentation of Anomalous Left Coronary Artery From the Pulmonary Artery: A Multicenter Study

We sought to describe the clinical course and outcomes of patients who are diagnosed with anomalous left coronary artery from the pulmonary artery (ALCAPA) after infancy. We conducted a retrospective evaluation of patients who underwent ALCAPA surgery between January 2009 to March 2018 at 21 US centers. Clinical presentation, inpatient management, and postoperative outcomes of patients repaired ≥1 year of age were described. To characterize this cohort, we compared these data to patients repaired before 1 year of age. Of 248 ALCAPA patients, 71 (29%) underwent repair ≥1 year of age. Among this subset, the median age at diagnosis was 8.3 years. Chronic arrhythmia occurred in 7%. Patients had good postoperative recovery of left ventricle (LV) dysfunction (90%) and LV dilation (75%), although a low incidence of recovery of mitral regurgitation (40%). Compared to infants, older patients were more likely to present with cardiac arrest (11% vs 1%) and less likely to have moderate or worse LV dysfunction or mitral regurgitation. Older patients had significantly less postoperative extracorporeal membrane oxygenation use, and shorter ICU and hospital stay. In the older cohort, operative mortality occurred in only 1 patient and no patient died after discharge (median follow-up 2.7 years). Survival of patients who presented with ALCAPA beyond infancy was excellent, although chronic mitral regurgitation and chronic arrhythmia were not uncommon. Patients who underwent ALCAPA repair ≥1 year of age were less likely to present with LV dysfunction but more likely to present with cardiac arrest than younger patients.

Surgical outcomes for anomalous left coronary artery from the pulmonary artery: Influence of late presentation

OBJECTIVES

Although surgical outcomes for anomalous left coronary artery from the pulmonary artery (ALCAPA) are excellent in the modern era with the coronary reimplantantion technique, mortality remains high in Chinese population. This study was undertaken to review the surgical management for ALCAPA in our center and assess the midterm outcomes.

METHODS

This was a retrospective review of 105 patients who underwent surgical repair for ALCAPA from January 2008 to January 2018.

RESULTS

The diagnosis of ALCAPA was not made before referred to our hospital in 31 patients (30%). Median age at repair was 7.6 months (interquartile range, 4.3-25.4 months). Mean preoperative left ventricular ejection fraction was 47.3% ± 16.9%. Concomitant mitral intervention was performed in 52 patients (50%). Mechanical circulatory support was used in 15 patients (14%). Early mortality was 14%. Classification and regression tree analysis identified 3 risk groups for early mortality, among which patients with preoperative left ventricular ejection fraction ≤41.6% and age at repair >127 days were the most likely to suffer from mortality. Using nonlinear mixed-effect model to assess the time course for postoperative left ventricular ejection fraction, patients of this group also needed significantly longer time for recovery of left ventricular function after surgery (P < .0001).

CONCLUSIONS

Late referral of patients with ALCAPA is not uncommon in our center. Older age at repair in patients with preoperative left ventricular dysfunction is the main reason for higher early mortality, and is also associated with longer time to normalization of left ventricular function after surgery.

Surgical Angioplasty of Stenotic Left Main Coronary Artery 15 Years After ALCAPA Repair

Studies regarding long-term results after repair of anomalous left main coronary artery from the pulmonary artery (ALCAPA) have mainly focused on survival rates, left ventricular function, and mitral valve function. The development of left main coronary stenosis following repair has been infrequently reported and its incidence unknown. Optimal therapy is also not known. Here we report the use of surgical angioplasty to achieve revascularization of a stenotic left main coronary artery in a patient with ALCAPA who had undergone coronary transfer 15 years earlier.

An experience with off pump technique for repair of anomalous left coronary artery from pulmonary artery (ALCAPA)

BACKGROUND

Anomalous origin of left coronary artery from pulmonary artery is a very rare disease with incidence of one every 300,000 live births. It has a high mortality of 80% in the first year of life. This observational study summarized our experience using the technique of subclavian arterial bypass without the use of cardiopulmonary bypass (CPB) for treatment of this coronary anomaly in pediatric population. The study aims to revive an earlier technique, with modifications, as an alternative to the existing coronary translocation.

METHODS

From 2009 till 2015, six consecutive infants were operated by a single surgeon using subclavian artery to left coronary artery bypass done off pump, to establish a two coronary circulation.

RESULTS

Five patients had an improvement in their LV ejection fractions at the time of the last follow-up. Angiography done in two cases after 2 and 6 years after surgery revealed good flow in the left coronary artery and good growth in the length of subclavian artery. There was one surgical mortality in this series.

CONCLUSIONS

The technique of off pump subclavian arterial bypass for anomalous origin of the left coronary artery from the pulmonary artery is a viable alternative to the existing standard technique of coronary translocation. It essentially eliminates extracorporeal circulatory support or a left heart bypass that may be needed after coronary translocation. Also, the advantage of avoiding CPB, both in economic terms and also the adverse effects related to use of bypass in this very sick hearts, cannot be disregarded.

Anomalous Origins of Coronary Arteries From the Pulmonary Artery: A Comprehensive Review of Literature and Surgical Options

Anomalous origins of coronary arteries from the pulmonary artery are rare malformations in which the coronary arteries originate from pulmonary artery sinuses or branches. The consequences are variable although, in most cases, these anomalies lead to severe coronary hypoperfusion and ventricular dysfunction. Surgical correction is indicated once the diagnosis is established due to high early mortality associated with the disease. In nearly all cases, the anomalous artery can be excised from its pulmonary origin, mobilized, and reimplanted directly into the ascending aorta using different surgical techniques. In rare circumstances, technical modifications must be used to restore a normal dual coronary perfusion. The emphasis of this article is to provide a collective review of surgical options published in the literature.

A rare cause of respiratory distress in the emergency department: anomalous origin of the left coronary artery from the pulmonary artery

Anomalous origin of the left coronary artery from the pulmonary artery is the most common cause of myocardial ischemia and infarction in children and infants. Most of the affected individuals become symptomatic, owing to dilated cardiomyopathy during the infant period. Because of congestive heart failure, pulmonary congestion and respiratory distress can be seen. Herein, we report a 35-day-old infant with anomalous origin of the left coronary artery from the pulmonary artery who presented with respiratory distress and dilated cardiomyopathy to draw attention to this rare surgically treatable anomaly.

Intermediate-term results of extracorporeal membrane oxygenation support following congenital heart surgery

BACKGROUND

Although there are considerable data regarding in-hospital results of congenital heart surgery (CHS) patients requiring postoperative extracorporeal membrane oxygenation (ECMO) support, there is limited information on intermediate-term outcomes.

METHODS

A single-institution retrospective review of 25 consecutive postoperative CHS patients who required ECMO and survived to hospital discharge between January 2003 and June 2008. Survival was estimated by the Kaplan-Meier method.

RESULTS

At a median follow-up of 3.3 years (interquartile range: 1.2-5.9 years), there was one death which occurred at six months postsurgery. Kaplan-Meier-estimated survival at three years was 95% (95% confidence interval: 90%-100%). Indications for ECMO included extracorporeal cardiopulmonary resuscitation (48%), systemic hypoxia (4%), postoperative low-cardiac output syndrome (28%), and intraoperative failure to wean off cardiopulmonary bypass (20%). Following ECMO support, 65% of patients had unplanned cardiac reinterventions (three requiring operative interventions, six requiring percutaneous interventions, and four requiring both), and 47% of patients required unplanned hospitalizations. In all, 29% of patients developed neurological deficits and 12% of patients developed chronic respiratory failure. No patients developed renal failure. Overall, systemic ventricular (SV) function normalized in 83% of patients, whereas 17% of patients had persistent mild-to-moderate SV dysfunction.

CONCLUSIONS

Intermediate-term patient survival of ECMO following CHS is encouraging. However, neurological impairment and unplanned cardiac reinterventions remain significant concerns. Further delineation of risk factors to improve patient outcomes is warranted.

Anomalous left coronary artery connected to the pulmonary artery associated with other cardiac defects: a difficult joint diagnosis

Anomalous left coronary artery connected to the pulmonary artery (ALCAPA) can be associated rarely with other congenital heart defects. The preoperative joint diagnosis is challenging. From 1987 to 2012, a retrospective bicentric assessment of 12 patients with ALCAPA related to other cardiac defects focused on the associated heart defect, the moment of complete diagnosis related to surgery, and outcome. Coarctation was the most frequently associated heart defect (n = 5) followed by tetralogy of Fallot with or without pulmonary atresia (n = 3). The study group comprised one case of hypoplastic left heart syndrome, one right aortic arch, one congenital mitral malformation, and one infant with divided left atrium and anomalous pulmonary venous return. Only four patients had a complete diagnosis of both the cardiac defect and the coronary abnormality before surgery. In two cases, the coronary anomaly was discovered during surgery performed for another cardiac defect and treated at the same time. The diagnosis of the six remaining patients was determined after cardiac repair. Of the 12 patients, 7 (58 %) died after surgery. Half of these patients died within the first 30 days after repair. At this writing, the remaining patients are in good health after a median follow-up period of 5.4 years (range, 2.1-8.5 years). This study confirmed that ALCAPA associated with other cardiac defects often is misdiagnosed before surgery, mostly due to specific hemodynamics masking myocardial ischemia preoperatively. Survival was compromised due to the unrecognized diagnosis of an associated coronary abnormality but also because of midterm complications related to the other cardiac defects.

Outcomes of coronary transfer for anomalous origin of the left coronary artery from the pulmonary artery

OBJECTIVES

To determine outcomes of patients presenting with an anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) who underwent coronary transfer, and to investigate the role of the left ventricular ejection fraction (LVEF) and preoperative myocardial viability as the predictors for incomplete LV functional recovery.

METHODS

From 2002 to 2012, 40 consecutive patients whose diagnosis was ALCAPA and who underwent coronary transfer were included. Seventeen patients (42.5%, 17/40) presented with LV dysfunction (Group I) while the other 23 (57.5%, 23/40) did not (Group II). All patients in Group I underwent myocardial perfusion/metabolism imaging and the global viability index was calculated. The mean follow-up time was 54 ± 37 months.

RESULTS

The median age at repair was 27.6 months (range, 3-66 months) and the mean preoperative LVEF was 49.0 ± 15.6%. Two extracorporeal membrane oxygenation support systems were required after correction. There were no in-hospital deaths and 1 late death. The mean LVEF was significantly improved to 61.0 ± 12.2 and 64.0 ± 11.2% at discharge and follow-up, respectively. Both the LVEF at discharge (52.7 ± 17.1% in Group I versus 66.1 ± 8.0% in Group II, P = 0.02) and the LVEF at the latest follow-up (55.2 ± 10.1% in Group I versus 67.6 ± 8.0% in Group II, P = 0.03) were lower in Group I than Group II. Moderate mitral regurgitations (MRs) were noted in 5 patients (12.8%, 5/39) at follow-up without difference between groups. Restrained functional recovery was observed in 6 patients (35.2%, 6/17) in Group I and the global viability index (P = 0.02) was identified as a predictor for incomplete LV functional recovery.

CONCLUSIONS

Coronary transfer is a technique of choice with favourable outcomes for this anomaly. In the majority of patients, both ventricular function and MR tend to be normalized over time. Myocardial viability may be an alternative predictor for restrained LV functional recovery.

What other anomalies? Failure to wean post ventricular septal defect repair secondary to anomalous origin of the left coronary artery from the pulmonary artery

A six week old infant underwent ventricular septal defect and atrial septal defect closure. Preoperative echocardiography showed evidence of pulmonary hypertension. The post operative course was complicated failure to wean from ventilatory and inotropic support. Echocardiography showed severe left ventricular (LV) dysfunction and suggested some fistulous drainage of the left coronary artery into the right pulmonary artery; this anomalous drainage of the left coronary artery into the right pulmonary artery (ALCAPA) was confirmed with coronary angiogram. Re-implantation of the left coronary artery into the aorta was performed. Extra-corporeal membrane oxygenation (ECMO) was required to allow time for ventricular recovery. Supports were weaned gradually, with concurrent evidence of LV recovery and the child was discharged on postoperative day 30. ALCAPA is rare and typically presents at 8 weeks of age with symptoms of heart failure, as pulmonary pressure falls leading to myocardial ischaemia due to myocardial hypoperfusion with relatively desaturated blood. In our case the pulmonary hypertension and left to right shunt preoperatively were protective, maintaining forward flow of relatively oxygenated blood. While protective to the myocardium this made the preoperative diagnosis of ALCAPA difficult, as there was no flow reversal on Doppler echocardiography. Closure of the septal defects meant this protective effect was lost, with subsequent severe myocardial ischaemia and heart failure. This case highlights the diagnostic challenges of ALCAPA, the 'protective' effects of pulmonary hypertension with ALCAPA, and the importance of early cardiac catheterization in the setting of unexplained failure to wean post cardiac surgery.

Use of the Batista procedure to discontinue bypass following aortic reimplantation of an anomalous left coronary artery

A four-month-old infant with anomalous origin of the left coronary artery from the pulmonary artery developed severe left ventricular failure after aortic reimplantation, despite prolonged supportive cardiopulmonary bypass with high level inotropic support and several abortive attempts for discontinuation. The Batista procedure was performed and the patient was successfully weaned from bypass. Postoperative recovery was uneventful, and at one-year follow-up she remains asymptomatic.
