Anatomically designed ablation catheters achieve pulmonary vein isolation (PVI) 35% faster than traditional point-by-point focal ablation procedures, a Medtronic study has found.

According to data released from the company’s FAST-PVI study at Cardiostim 2010, the acute-PVI success rate for the anatomical catheters was 99%.

The anatomically shaped Arctic Front Cardiac CryoAblation Catheter, approved in Europe to treat paroxysmal atrial fibrillation, was discovered to allow physicians to more efficiently isolate the pulmonary veins than focal radiofrequency catheters.

Medtronic’s advanced radiofrequency Pulmonary Vein Ablation Catheter, approved in Europe to treat supraventricular tachycardia, was also found to be more efficient at performing PVI procedures.

The retrospective FAST-PVI study was conducted in nine German medical centres, comparing procedure time between anatomically designed catheters and traditional focal systems.

Both the Arctic Front Cardiac CryoAblation Catheter and Pulmonary Vein Ablation Catheter are under investigational use in the US.
