The Comparative Advantage of the Optrell Mapping Catheter in Ventricular Arrhythmias From the Papillary Muscles

The Comparative Advantage of the Optrell Mapping Catheter in Ventricular Arrhythmias From the Papillary Muscles

We believe that the design of the Optrell™ mapping catheter with TRUEref technology allows for faster and more accurate mapping not only due to narrow electrode spacing but also due to the ability to achieve simultaneous contact of multiple bipoles with the surface of the papillary muscle. Simultaneous mapping of multiple sites on the same surface will allow operators to appreciate small activation differences that typically exist between neighboring sites during papillary muscle ventricular arrhythmias. In addition, the position of the Optrell™ mapping catheter on the papillary muscle allows the mapping catheter to move with the papillary muscle rendering a more accurate allocation of the activation time to the surface of the papillary muscle. We also believe that optimal positioning between the Optrell™ mapping catheter and papillary muscles can be assisted by using intracardiac echocardiography. The goal of the study is to explore the utility and superiority of a specific mapping catheter, the Optrell™ mapping catheter with TRUEref.
