    This procedure is done to disable heart cells that are creating an irregular heartbeat called
    arrhythmias. After the procedure, normal heart rhythm should be restored.

  • 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.
