Cardiac resynchronization therapy in a patient with pacemaker-induced cardiomyopathy

Abstract

There is a high prevalence of cardiac stimulation therapy complications; however, they are frequently forgotten by medical personnel. Cardiomyopathy secondary to biventricular dyssynchrony due to high right ventricular stimulation is a frequent cause of heart failure, increasing the risk of death and hospitalization and decreasing the quality of life of patients with pacemakers. We present a case of a patient who developed heart failure. The most common causes of left ventricular dysfunction were ruled out, and it was determined to be secondary to pacemaker-induced cardiomyopathy. The patient´s device was changed to biventricular cardiac resynchronization therapy, with an adequate clinical response. We highlight the importance of looking for complications related to right ventricular stimulation devices in patients with heart failure, and of considering a change to biventricular stimulation within the treatment plan
