Percutaneous multielectrode endocardial mapping and ablation of ventricular tachycardia in the swine model

A basket shaped catheter carrying 64 electrodes was developed in the left ventricle (LV) of 53 pigs which had undergone induction of myocardial infarction.

Description
Summary:	A basket shaped catheter carrying 64 electrodes was developed in the left ventricle (LV) of 53 pigs which had undergone induction of myocardial infarction. Pacing during sinus rhythm, or echocardiographic and hemodynamic measurements as well as pathological studies revealed no significant damage due to the basket catheter. Eighty one episodes of ventricular tachycardia (VT) were mapped and analyzed, requiring only several beats and less than 10 seconds to complete. We were able to successfully ablate ventricular tachycardias in four pigs.
