Cardiac resynchronization therapy in a patient with a failing systemic right ventricle.
Systemic right ventricular dysfunction is 1 of the late complications of the atrial switch operation for transposition of the great arteries. It has been reported that cardiac resynchronization therapy (CRT) for the failing systemic right ventricle (RV) improves symptoms and systolic function. However, patient selection for CRT in congenital heart disease is still challenging because the clinical standard for CRT in these patients is not established. We describe a case of successful implantation of a CRT device for a failing systemic RV aided by multimodality imaging and cardiac hemodynamic studies.
