Nuances of Cardiac Resynchronization Therapy in Patients with Dilated Cardiomyopathy and Atrial Fibrillation (a Clinical Case)

Abstract

Dilated cardiomyopathy (DCM) is a steadily developing disease characterized by progressive chronic heart failure (CHF) resistant to drug therapy. Cardiac resynchronization therapy (CRT) significantly improves the prognosis in these patients if they have indications for implantation of resynchronization devices. The article presents a clinical case of successful implantation of a cardioversion-defibrillation cardiac resynchronization device in a patient suffering from DCM in combination with permanent atrial fibrillation (AF). The nuances of ventricular rate control and the role of the catheter procedure for modifying the atrioventricular junction are discussed.
