Cryoablation for A-Fib Now Available at Western Connecticut Health Network

Danbury Hospital

Patients with drug refractory, symptomatic, paroxysmal atrial fibrillation (AF) have a new treatment option.

Danbury Hospital of Western Connecticut Health Network (WCHN) is one of the first hospitals in CT to offer cryoablation, a new technology that allows cardiac electrophysiologists to restore normal heart rhythm by using a thin, flexible balloon catheter to freeze the heart tissue around the pulmonary veins that can trigger irregular heartbeat. 

  • This minimally-invasive procedure takes about two hours and patients go home the next day. 
  • Recovery requires a 48-hour restriction on physical activity. 
  • Nearly 90 percent of patients treated with the cryoballoon achieved freedom from AF at one year, and 85 percent were free from AF, symptomatic atrial flutter and atrial tachycardia.1
