Mayo Clinic is an international leader in cardiac catheter ablation and uses the most advanced technology to treat heart arrhythmias. Most Mayo patients who undergo catheter ablation are cured of their heart arrhythmia and no longer require medication.
Catheter ablation is a minimally invasive procedure that does not require open heart surgery. In catheter ablation, catheters (thin, flexible tubes) are threaded through the patient's blood vessels to reach the heart and destroy (ablate) abnormal heart tissue.
At Mayo Clinic, catheter ablation may be used to treat:
Mayo Clinic has used catheter ablation to successfully treat thousands of patients with heart arrhythmias. Ongoing research at Mayo Clinic is focused on designing even better interventions for ablation of heart arrhythmias.
Patients benefit from the expertise and experience of the catheter ablation team at Mayo Clinic. The catheter ablation team is led by electrophysiologists (cardiologists with specialized training in the diagnosis and treatment of heart rhythm disorders). Patients also benefit from Mayo Clinic's leading-edge technology and state-of-the-art diagnosis and treatment facilities. Catheter ablation is often effective, and risks and complications such as heart injury or infection are uncommon. Physicians can advise patients on the most appropriate treatment for their condition.
Catheter ablation has numerous advantages:
The types of catheter ablation most commonly performed at Mayo Clinic include:
In rare cases, other types of catheter ablation may be performed, depending on the cause and severity of the patient's heart arrhythmia.
Cardiac catheter ablation is a minimally-invasive procedure performed to treat heart rhythm disorders. In this procedure, catheters (thin, flexible tubes) are threaded through the patient's blood vessels to reach the heart. Radiofrequency energy (heat), a laser or nitrous oxide (extreme cold) is applied through the catheter tip to the abnormal heart tissue. The energy destroys (ablates) the abnormal heart tissue causing the heart rhythm disorder.
Catheter ablation is performed by electrophysiologists (cardiologists with specialized training in the diagnosis and treatment of heart rhythm disorders). Several types of catheter ablation may be performed, depending on the cause and severity of the patient's heart rhythm disorder. Many types of heart rhythm disorders may be treated successfully by catheter ablation. Some patients may still need treatment with medications or implantable devices after the procedure.
