Percutaneous edge-to-edge tricuspid valve repair in congenitally corrected transposition of the great arteries

Abstract

To the Editor, The congenitally corrected transposition of the great arteries is a rare congenital defect characterized by atrioventricular and ventriculoarterial discordance. As a result, the tricuspid valve and the anatomical right ventricle sustain the systemic circulation. Typically, the patient remains asymptomatic at an early age, but the right ventricle and the tricuspid valve deteriorate with the passing of time. The only curative treatment for this condition is heart transplant. In this setting, percutaneous edge-to-edge tricuspid valve repair has been traditionally used to treat tricuspid regurgitation in patients who are ineligible for heart transplantation; however, to this date, the evidence available is scarce and based on case reporting in heterogeneous clinical settings.1-3
