Radiofrequency ablation is a procedure used to treat specific kinds of cardiac arrhythmias. It destroys the cardiac cells that generate the abnormal impulses.
The most common kind of arrhythmia is atrial fibrillation, characterized by rapid beating of the upper chambers of the heart. Until recently, this arrhythmia was treated with medications alone and was difficult to control. Drexel electrophysiologists have a history of innovation in the treatment of atrial fibrillation. They helped develop nonsurgical atrial fibrillation ablation techniques using catheters or minimally invasive surgery. Today, the procedure offers patients improved control or possibly even cure of this arrhythmia.
Cardiac Ablation Procedure
To perform the procedure, the electrophysiologist guides an electrode-tipped catheter to the precise area of the heart that is producing the disruptive electronic signals. Extremely hot or cold temperatures (cryoablation) are applied to the area, destroying a small amount of tissue at this specific site, which can stop the irregular heartbeats or make them easier to control with medication.
Cryoablation enhances patient safety by allowing electrophysiologists to perform cryomapping or site testing. It produces a temporary electrical blockage, so that the physician can be certain that the exact area responsible for the irregular impulses has been located. If so, the area is permanently disabled.
For catheter ablation procedures, the patient receives mild sedation with local anesthesia and experiences little or no discomfort. Patients can usually return to their usual activities within a few days. After the four- to six-hour procedure, patients recuperate in a special care unit where the heart rate is carefully monitored. Patients may be discharged that day or stay overnight in the hospital. Prior to returning home, the patient receives instructions regarding medications, self-care, and activity.
Preparation for the Cardiac Ablation Procedure
Patients may be advised to discontinue certain medications from one to five days before the procedure. Persons with diabetes should consult their doctor on how to adjust their medications. Patients should not eat or drink anything after midnight on the evening before the procedure.
