Soundararajan, Deep ChandhSanders, PrashanthanPathak, Rajeev2024-01-161877-9182http://hdl.handle.net/1885/311501Intracardiac echocardiography (ICE) has evolved into an indispensable tool in the armamentarium of cardiac electrophysiologists not only for understanding the internal cardiac anatomy but also for establishing transseptal access and for monitoring electrophysiology procedures. ICE aids in live monitoring of every step of the procedure including early detection of complications. Access to the left atrium through transseptal catheterization is a vital step to perform atrial fibrillation and accessory pathway ablations, ablation of left ventricular tachycardias, left atrial appendage closures, left ventricular endocardial electrode implantations for cardiac resynchronization therapies, and for selectively sampling the regions of interest during endomyocardial biopsies.Dr P.
