Abstract
Cardiac resynchronization therapy (CRT) is achieved by implanting a biventricular pacemaker (BiV) into patients suffering from congestive heart failure secondary to a dilated cardiomyopathy. Congestive heart failure patients are first treated with standard heart failure drug therapy; however, if this therapy is not sufficient and the patients meet specific criteria, they can be selected for CRT. This therapy can create vast cardiac and symptomatic improvements in a relatively short time. This case report discusses the characteristics of a dilated cardiomyopathy before and after CRT and the associated cardiac improvements. Sonography continues to play an important role in diagnosing dilated cardiomyopathies, as well as congestive heart failure, and monitoring the progression after treatment.
