Port Blair, Aug 11: The ANIIMS's Interventional Cardiology Unit performed a case of Conduction system pacing (Lt bundle pacing) and Cardiac resynchronization therapy (CRT-D) implantation successfully in a single day for the first time in the history of A&N Islands on July 17, 2023. Conduction system pacing is a mode of physiological pacing, carried out for the first time in the world in 2018 in China. Since then, only a small number of centers in the nation have been capable of performing such sophisticated pacing techniques.

The first patient was a 66-year male who presented with syncope with intermittent complete heart block with left ventricular (LV) dysfunction. He underwent left bundle pacing successfully with complete resolution of symptoms. The second patient was a 51-year female diagnosed with dialated cardiomyopathy (DCMP) severe LV dysfunction with complete Lt bundle branch block with recurrent hospitalizations with heart failure. She underwent CRT- D (Biventricular pacemaker) successfully with a complete reversal of Left Bundle Branch Block (LBBB). The procedures were carried out by a team of Cardiologists, Electrophysiology (EP) technicians, Cath lab technicians, and Cath lab nursing staff lasting over seven hours. Both patients have been discharged and are doing well on follow-up with excellent pacing parameters.
