First report from the European registry for anomalous aortic origin of coronary artery (EURO-AAOCA).

OBJECTIVES: Anomalous aortic origin of a coronary artery (AAOCA) is a group of rare congenital heart defects with various clinical presentations. The lifetime-risk of an individual living with AAOCA is unknown, and data from multicentre registries are urgently needed to adapt current recommendations and guide optimal patient management. The European AAOCA Registry (EURO-AAOCA) aims to assess differences with regard to AAOCA management between centres. METHODS: EURO-AAOCA is a prospective, multicentre registry including 13 European centres. Herein, we evaluated differences in clinical presentations and management, treatment decisions and surgical outcomes across centres from January 2019 to June 2023. RESULTS: A total of 262 AAOCA patients were included, with a median age of 33 years (12-53) with a bimodal distribution. One hundred thirty-nine (53.1%) were symptomatic, whereas chest pain (n = 74, 53.2%) was the most common complaint, followed by syncope (n = 21, 15.1%). Seven (5%) patients presented with a myocardial infarction, 2 (1.4%) with aborted sudden cardiac death. Right-AAOCA was most frequent (150, 57.5%), followed by left-AAOCA in 51 (19.5%), and circumflex AAOCA in 20 (7.7%). There were significant differences regarding diagnostics between age groups and across centres. Seventy-four (28.2%) patients underwent surgery with no operative deaths; minor postoperative complications occurred in 10 (3.8%) cases. CONCLUSIONS: Currently, no uniform agreement exists among European centres with regard to diagnostic protocols and clinical management for AAOCA variants. Although surgery is a safe procedure in AAOCA, future longitudinal outcome data will hopefully shed light on how to best decide towards optimal selection of patients undergoing revascularization versus conservative treatment.

Percutaneous recanalization of a chronic total left main coronary artery occlusion in an 8-year-old child after arterial switch surgery.

How and when to treat patients with coronary occlusion after arterial switch surgery is still under debate. We report the case of a child who underwent arterial switch surgery a few weeks after birth. At the age of 8 years, coronary angiography showed a total occlusion of the left main coronary artery, successfully treated using percutaneous coronary intervention. Percutaneous coronary recanalization of chronic total occlusions might be considered the first treatment strategy in children who undergo complex surgical procedures.

Two cases of double-outlet left ventricle detected prenatally.

Double-outlet left ventricle is an exceedingly rare congenital heart defect. Its prenatal detection and precise anatomical definition are challenging for a variety of reasons and have never been previously reported. Here described are 2 cases of prenatally diagnosed double-outlet left ventricle. The technical limitations of prenatal diagnosis and its implications for the surgical management of patients affected by such a rare condition are discussed.
