Abstract

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 enddiastolic 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.
