Bundle-branch reentry ventricular tachycardia after transcatheter aortic valve replacement.

de la Rosa Riestra A, Rubio Caballero JA, Freites Estévez A, Alonso Belló J, Botas Rodríguez J - Indian Pacing Electrophysiol J (2016)

Bottom Line: The patient was wearing an ECG holter monitor that day, which showed a wide QRS complex tachycardia of 300 beats per minute.Radio-frequency was applied on the right-bundle branch.Twelve months later, the patient has remained asymptomatic.

ABSTRACT
An 83-year-old male suffering from severe symptomatic aortic valve stenosis received an implant of a biological aortic prosthesis through the femoral artery without complications. Seven days after dischargement he experienced a syncope. The patient was wearing an ECG holter monitor that day, which showed a wide QRS complex tachycardia of 300 beats per minute. The electrophysiological study revealed a bundle-branch reentry ventricular tachycardia as the cause of the syncope. Radio-frequency was applied on the right-bundle branch. Twelve months later, the patient has remained asymptomatic.

No MeSH data available.

A. ECG at initial evaluation showed sinus rhythm with an incomplete right-bundle branch block and left anterior hemiblock. B: after Corevalve 29 implantation the ECG showed a slight widening of the QRS. C: Ventricular tachycardia at 300 bpm.

Mentions: An 83-year-old male suffering from severe symptomatic aortic valve stenosis and, being a high surgical risk, received an implant of a biological aortic prosthesis (Corevalve 29) through the femoral artery. During the evaluation prior to the implant, the electrocardiogram (ECG) (Fig. 1A) showed sinus rhythm with an incomplete right-bundle branch block and left anterior hemiblock. The echocardiogram showed signs of calcifications in the aortic valve with a peak gradient of 90 mmHg and a medium gradient of 60 mmHg. The left ventricle showed good global and segmental contraction and the coronography showed insignificant irregular coronary vessels.
