A case of 15-year misdiagnosed heart failure: congenitally corrected transposition of the great arteries.

Abstract

Congenitally corrected transposition of the great arteries (CCTGA) is a rare condition, accounting for about 1% of all congenital heart diseases1, and more than 90% of patients have associated anomalies like ventricular septal defect, pulmonary stenosis, and systemic atrioventricular valve anomalies2. European Society of Cardiology (ESC) guidelines recommend systemic atrioventricular valve surgery for severe regurgitation before systemic ventricular function deteriorates (before right ventricular ejection fraction <45%)1.
