PERCUTANEOUS PERICARDIAL APPROACH FOR RADIOFREQUENCY CATHETER ABLATION OF EPICARDIAL VENTRICULAR TACHYCARDIA

Background Radiofrequency catheter ablation represents effective endocardial treatment modality, of supraventricular tachyarrhythmias, idiopathic ventricular tachycardias, as well as some forms of ventricular tachycarida associated with structural heart disease. However, radio-frequency ablation through endocardial approach sometimes fails due to epicardially located substrate or is not feasible due to prosthetic valves or ventricular thrombus. 117 Such cases, percutaneous subxyphoid puncture offers relatively non-invasive access to pericardial dial space and epicardial surface of the heart, Conclusions Although technically demanding procedure is relatively non-invasive and safe, In 2007, this methodology was also introduced in. our institution.
