Abstract

Objectives: It remains unclear when sudden cardiac event risk outweighs surgical risk for patients with anomalous aortic origin of a coronary artery. The Congenital Heart Surgeons' Society sought to characterize the surgical risks by determining the techniques, complications, and outcomes of repair. Methods: Between January 2000 and September 2018, 682 patients with anomalous aortic origin of a coronary artery aged 30 years or less were enrolled. Demographic, morphologic, operative, imaging, and ischemia-related data were analyzed. Results: There were 395 of 682 (57%) surgical patients (45 centers, median follow-up 2.8 years). In addition to primary repair (87% unroofing, 26% commissural manipulation), 13 patients had 15 coronary-related reoperations. Of 358 patients with pre/postoperative aortic insufficiency assessment, 27 (8%) developed new mild or greater aortic insufficiency postoperatively, and 7 (2%) developed new moderate or greater aortic insufficiency. Freedom from mild aortic insufficiency differed in those with versus without commissural manipulation (85%/91% at 6 months, 83%/90% at 1 year, and 77%/88% at 3 years, respectively) (P =.05). Of 347 patients with preoperative/postoperative ejection fraction, 6 (2%) developed new abnormal ejection fraction (<50%) within 30 days of surgery which persisted. Although 64 of 395 patients (16%) had preoperative ischemia, after surgery 51 of 64 patients (80%) no longer had ischemia (13 = new postoperative ischemia, P <.0001). Four patients died postoperatively (preoperatively 2 asymptomatic, 1 symptomatic, 1 in extremis). Composite surgical adverse event rates were 7% to 13% in the entire cohort (increasing/decreasing by presentation/anatomy/repair strategy). Conclusions: Anomalous aortic origin of a coronary artery surgery may relieve ischemia with low mortality; however, it can result in a variety of important morbidities, varying by the group evaluated. Strategies avoiding commissural manipulation may decrease the risk of developing aortic insufficiency. Understanding these risks should inform surgical decision-making and support the need for standardized assessment and management.
