Catheter Ablation for Cardiac Arrhythmias
In some cases, an abnormal area of heart muscle produces irregularities in the transmission of electrical impulses in the heart, resulting in cardiac arrhythmia — a rapid or irregular heartbeat. As a result of cardiac arrhythmia, the heart is not able to pump blood normally. Depending on the type of arrhythmia, this situation can lead to a variety of symptoms, congestive heart failure, or even stroke.
Physicians at NewYork-Presbyterian can often cure arrhythmias by interrupting the path of the electrical impulses that produce them, a technique called ablation. Cardiologists at NewYork-Presbyterian can treat both supraventricular arrhythmias (including atrial fibrillation) and ventricular arrhythmias as part of a catheter procedure. Performed in a cardiac electrophysiology laboratory, catheter ablation causes less discomfort and results in faster recovery times than open-heart surgery.
In catheter ablation, an electrode catheter is inserted into a vein and guided to the diseased area. Radiofrequency energy or freezing temperature is applied to the abnormal area of heart tissue. This interrupts the path of the abnormal electrical impulses, thus curing the arrhythmia — one of the major causes of sudden cardiac death.
