Transatrial chemical ablation of ischemic ventricular tachyarrhythmias

Various surgical procedures have been devised for medically refractory ischemic ventricular tachyarrhythmias. All of these currently employed procedures require a ventriculotomy that may further compromise poor ventricular function. This study documents the efficacy of transatrial chemical ablation of the ventricular endocardium in controlling PVT. The effectiveness of this procedure and the ability to perform it without a ventriculotomy represent advances that may provide a means of treating patients with severe, global left ventricular dysfunction whose ventricular tachyarrhythmias are refractory to nonsurgical therapy.
