Overview

Definition

Cryoablation uses extremely cold temperature to destroy cells. Cardiac catheter cryoablation is used to destroy selected heart cells.

Possible Complications

Complications are rare, but no procedure is completely free of risk. If you are planning to have cardiac catheter cryoablation, your doctor will review a list of possible complications, which may include:

  • Bleeding
  • Infection
  • Pain at the catheter insertion site
  • Blot clot formation
  • Injuries to blood vessels or the heart
  • Abnormal heart rhythm
  • Heart attack
  • Heart tear

Factors that may increase the risk of complications include:

  • Smoking
  • Chronic diseases

Your level of risk may be related to the specific arrhythmia that you have and any underlying medical conditions.
