Adult Dilated Cardiomyopathy Patient with Wolff-Parkinson-White Syndrome

Abstract

We report on catheter ablation and clinical results in an adult with Wolff-Parkinson-White (WPW) syndrome for dyssynchrony-related dilated cardiomyopathy in the absence of supraventricular tachycardia (SVT). This patient did not have sustained SVT, but developed rapid progression of ventricular dysfunction that was not responsive to heart failure medication. Ventricular preexcitation could not be medically suppressed, but was successfully ablated. This was followed by complete resolution of ventricular dysfunction within six months.
