Mechanisms for Heart Failure in Systemic Right Ventricle

There are two predominant scenarios where the right ventricle acts as the systemic ventricle, namely congenitally corrected transposition of the great arteries (CC-TGA) and patients with D-transposition of the great arteries (D-TGA) who have undergone an atrial switch operation. There is evidence that having a right ventricle in the systemic position predisposes to the development of heart failure. In this review, we aim to explore the proposed mechanisms and pathophysiology for heart failure in patients with a systemic right ventricle in these two subsets of patients.
