Successful Radiofrequency Catheter Ablation of Ventricular Tachycardia Originating from Underneath the Mechanical Prosthetic Aortic Valve

PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 5 2008
TAKUMI YAMADA M.D.
A 67-year-old man who developed sustained ventricular tachycardia (VT) 4 years after a prosthetic aortic valve replacement, underwent electrophysiologic testing and catheter ablation. The mechanism of the VT was suggested to be triggered activity because the VT could be induced by programmed ventricular stimulation, and burst ventricular pacing demonstrated overdrive suppression without a transient entrainment. Successful catheter ablation using a transseptal approach was achieved underneath the mechanical prosthetic aortic valve on the blind side for that approach. This case demonstrated that catheter mapping and ablation of the entire LV using a transseptal approach might be possible. [source]

A Conservative Approach to Performing Transseptal Punctures Without the Use of Intracardiac Echocardiography: Stepwise Approach with Real-Time Video Clips

JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 6 2007
ALAN CHENG M.D.
Atrial transseptal puncture as a means of accessing the left heart is a critical component of catheter ablation procedures for atrial fibrillation, left-sided accessory pathways, and access to the left ventricle in patients with certain types of prosthetic aortic valves. Although this technique has been performed successfully since the 1950s, severe and potentially life-threatening complications can still occur, including cardiac tamponade and/or death. Some have adopted the use of intracardiac echocardiography, but our laboratory and many others throughout the world have successfully relied on fluoroscopic imaging alone. The aim of this brief report is to describe in detail our technique for performing transseptal punctures during catheter ablation procedures for atrial fibrillation. We employ a similar approach when targeting left-sided accessory pathways, although only a single transseptal is performed in those cases. Utilizing a series of real-time video clips, we describe our technique of double transseptal puncture and illustrate in detail ways in which to avoid common pitfalls. [source]
