Pulse Field Ablation Used in Complex Atrial Fibrillation Case
A woman had an irregular heartbeat that kept coming back.
She also had a condition that made her heart muscle unusually thick.
Her medicines and a heart device had not stopped the problem or repeated hospital stays.
Doctors used a treatment called pulse field ablation to target areas linked to the irregular heartbeat.
It uses short electrical pulses rather than heat or extreme cold.
The hospital said her atrial fibrillation was not documented during the first 30 days after treatment.
That is an early result, and doctors need to watch her for longer to know how well it lasts.
This one case does not show whether the treatment will work for everyone.
A 62-year-old woman with recurrent atrial fibrillation and hypertrophic obstructive cardiomyopathy underwent pulse field ablation.
The procedure was performed at BM Birla Heart Hospital in Kolkata.
She had experienced repeated heart-failure hospitalisations despite treatment and an implantable cardioverter-defibrillator.
Doctors used pulse field ablation for pulmonary vein isolation and to treat the left atrial posterior wall.
The hospital reported no clinically documented atrial fibrillation during the first 30 days; longer follow-up is needed to assess durability.
