Nonpharmacologic Therapy for Malignant Ventricular Tachyarrhythmias in Patients with Congestive Heart Failure

Abstract

Malignant ventricular tachyarrhythmias constitute an important cause of sudden cardiac death in patients with congestive heart failure [25]. It is increasingly recognized that despite effective treatment of congestive heart failure, life-threatening ventricular tachyarrhythmias may abbreviate patient survial. The frequency of this complication impacts significantly on the overall clinical outcome of these patients. In some instances, the therapeutic agent chosen for the treatment of congestive heart failure, for example, certain inotropic agents, may actually aggravate the ventricular tachyarrhythmia [23]. Surgical therapy in patients with congestive heart failure is also not immune to this complication. It is well-established that patients who have undergone aortic valve replacement for severe aortic valvular stenosis may experience postoperative sudden cardiac death. Clinical studies have suggested an association with the presence of complex ventricular tachyarrhythmias and nonsustained ventricular tachycardia (VT) on Holter monitoring. Similarly, patients who have undergone visually guided resection of a ventricular aneurysm or non-map-guided surgical resection of ventricular myocardium have a higher risk of recurrent postoperative ventricular tachyarrhythmias than patients who have undergone map-directed operations [40]. Finally, the presence of complex ventricular tachyarrhythmias or nonsustained VT in patients with left ventricular dysfunction due to a variety of anatomic abnormalities is an independent predictor of sudden cardiac death.
