The electrophysiology team at Rocky Mountain Heart Rhythm Institute (RMHRI) are the region’s leaders in the use of cryoballoon ablation as a method to treat atrial fibrillation (AFib).

For patients with AFib, a condition that causes patients to have irregular heartbeats, cryoballoon ablation utilizes a minimally invasive catheter approach to treat the electrical triggers that cause AFib.

How Does Cryoballoon Ablation Work?

A catheter approach is used to ablate tissue in the pulmonary veins of the left atrium of the heart. Inserted through the femoral vein in the groin, a specialized catheter then enters the right atrium before navigating to the left atrium, the source of the AFib. The balloon-tipped catheter is then positioned in the four pulmonary veins and releases liquid nitrogen designed to immobilize the area of the left atrium causing the irregular heartbeat.

The cells that are intentionally frozen through the cryoballoon ablation procedure are now unable to electrically conduct signals through the heart, therefore decreasing their ability to cause rapid and irregular heart rhythms.

Why Cryoballoon Ablation?

The ability to completely understand each patient’s condition is key in determining which procedure is the best course of treatment for each patient.

Cryoballoon ablation is specifically designed to treat the pulmonary veins of the left atrium. The procedure is more effective and safer than radiofrequency ablations because it not only covers a larger surface area of the pulmonary vein, but also has a decreased chance of injuring adjacent structures of the heart. Cryoballoon ablation also produces a higher single session treatment success rate than radiofrequency ablation.

Each patient’s heart is different and requires a different approach to treatment. The Rocky Mountain Heart Rhythm Institute team is one of the best, most diversely trained teams in the country. RMHRI electrophysiologists have performed the procedure numerous times and with great success.
