Abstract

Introduction Coronary artery anomalies comprise a heterogeneous group of rare congenital heart defects, being classified according to their origin, course and distal bed, with an incidence ranging between 0.3% and 1.5% in the overall population. Dodge-Khatami et al. subdivided them into seven categories, according to their clinical complexity: coronary arteries originating from the pulmonary artery, coronary arteries with anomalous aortic origin, congenital atresia of the left main coronary artery, coronary arteriovenous fistulas, coronary arteries forming myocardial bridges, coronary artery aneurysms [...]

Highlights

Coronary artery anomalies comprise a heterogeneous group of rare congenital heart defects, being classified according to their origin, course and distal bed, with an incidence ranging between 0.3% and 1.5% in the overall population
A previously healthy 31-year-old male patient, a mason, was admitted to the Emergency Unit in October 2012, complaining of palpitations and cold sweats, with hypotension (BP = 90 x 50 mmHg), which developed into syncope at the hospital unit. He was submitted to the first electrocardiogram (Figure 1A), which disclosed sustained monomorphic ventricular tachycardia (SMVT)
Ventricular arrhythmias comprehend a spectrum that range from ventricular extrasystoles, VT, to ventricular fibrillation
