Thromboembolic Complications of Cardiac Radiofrequency Catheter Ablation

Thromboembolic Complications of Cardiac RF Catheter Ablation. Introduction: Radiofrequency catheter ablation (RFCA) has become established as an effective therapy for the treatment of many cardiac tachyarrhythmias. The principle limitation of conventional RFCA continues to be the risk of thromboembolism. This risk is of particular concern for the ongoing development of the catheter maze procedure for the treatment of atrial fibrillation, which currently involves the creation of extensive linear lesions in the left atrium.
