Radiofrequency Energy to Treat Structural Heart Disease

Also known as: radiofrequency ablation, cardiac ablation.

What is radiofrequency energy to treat abnormal heart rhythms?

Heart disease not only refers to problems with the structure of the heart, but may also refer to problems with the electrical wiring of the heart, leading to abnormal heart rhythms or irregular heartbeats. Some of these problems are present at birth. Patients with structural heart disease often have to be corrected with surgery. However, those with abnormal heart rhythms or irregular heartbeats may often be treated with radiofrequency energy, instead.

Radiofrequency energy refers to the use of special electricity or radio waves to disrupt the abnormal electrical activity of heart muscle.

What happens during the procedure?

A specialized catheter is inserted into a blood vessel, often at the groin or neck, which leads to the heart. The catheter is guided to the heart, where electrodes are used to locate the specific areas of the heart that are contributing to the abnormal rhythm. Radiofrequency energy is then delivered to that specific area to disrupt the abnormal electrical circuit, so that the heart will no longer go into an abnormal rhythm.

Is any special preparation needed?

You likely will need to stop eating or drinking anything at midnight the night before the procedure. You may also need to stop taking certain medications.

What are the risk factors?

Risks of the procedure include damage from the catheter, damage to the normal wiring of the heart requiring a pacemaker, damage to heart valves, bleeding, blood clots or fluid around the heart.

Pacemaker and Implanted Internal Defibrillator Therapy

A pacemaker and implanted internal defibrillator are devices implanted in the chest to control your heart rate. A pacemaker keeps the heart rate steady with electrical pulses if you have arrhythmia. If you have dangerous arrhythmia, the implanted internal defibrillator shocks the heart when the rhythm becomes dangerous. Learn more
