Intracardiac Echocardiography: Use of Intracardiac Echocardiography to Guide Catheter Ablation
Papillary muscle ventricular arrhythmias remain technically demanding targets for catheter ablation due to complex intracavitary anatomy and unstable catheter contact. This case report illustrates how intracardiac echocardiography enables real-time anatomical visualization, optimizes lesion delivery, and facilitates durable arrhythmia elimination when conventional mapping alone proves insufficient.
