PULSE FIELD ABLATION (PFA)

New Era in AFib Treatment

Safer. Precise. Proven. Faster
A groundbreaking advancement in the treatment of Atrial Fibrillation (AFib) is now available.
Pulsed Field Ablation (PFA) is a next-generation, non-thermal technology designed to restore normal heart rhythm with exceptional precision while significantly improving procedural safety.
Unlike traditional thermal ablation (radiofrequency or cryoablation), PFA uses precisely delivered electrical pulses that preferentially affect cardiac tissue while minimizing collateral damage.
This treatment is now offered by Dr. Alireza Nazeri at Mobitz AFib Clinic and affiliated facilities, including Houston Methodist Hospital.

Watchman Procedure

The Watchman device is a small, parachute-shaped implant designed to seal off the left atrial appendage. By closing this area, it prevents clots from forming there and reduces the chance they will travel through the bloodstream.
