Abstract:
Cardiac resynchronization therapy is recommended in patients with advanced heart failure (usually NYHA class III or IV) despite optimal pharmacologic therapy, severe systolic dysfunction (eg, left ventricular ejection fraction < 35 percent) and intraventricular conduction delay or echocardiographic indices of dyssynchrony and wide QRS complex (eg, QRS > or = 120 ms). Viral infection is the most common cause of myocarditis and has been implicated in the development of non-ischemic cardiomyopathy. We report on a patient who developed progressive congestive heart failure caused by non-ischemic cardiomyopathy after liver transplantation and reactivation of the underlying hepatitis C. Due to an insufficient response to optimized pharmacological therapy, the patient was successfully treated using cardiac resynchronization therapy.
