Bundle branch reentrant tachycardia in a patient with a calcified bicuspid aortic valve and normal ventricular function

Clin Res Cardiol. 2006 Mar;95(3):168-73. doi: 10.1007/s00392-006-0343-5. Epub 2006 Jan 12.

Abstract

We report the case of a bundle branch reentrant tachycardia (BBRT) in a 40-yearold patient with a calcified bicuspid aortic valve and normal left ventricular function. The ventricular tachycardia was eliminated by successful radiofrequency ablation of the right bundle branch. As the aortic valve annulus is in close proximity to the specialized conduction system, premature degeneration of a bicuspid aortic valve may involve the bundle of His and the proximal bundle branches by invading calcifications. We speculate that calcifications invading the proximal bundle branches from the bicuspid aortic valve may have created the substrate for the BBRT in this patient.
