Abstract

Congenitally corrected transposition of the great vessels (CCTGA) is a rare congenital heart defect. Patients with CCTGA have the anatomical right ventricle as their systemic pumping chamber, with ventricular dysfunction and congestive heart failure (CHF) being relatively common in older adults. The most common presenting feature is bradycardia due to high-degree atrioventricular (AV) blocks. Patients with CCTGA are increasingly subject to CHF with advancing age; this complication is extremely common by the fourth decade. The majority of patients have an inverted coronary arterial pattern.1 We report a case of a patient with CCTGA who presented with rare but life-threatening ventricular tachycardia (VT) leading to syncope, with preserved systemic ventricular function. Coincidentally, the patient also had a single coronary ostium.
