An apparatus for bipolar radio frequency ablation of heart tissue includes a flexible epicardial lead having an interior surface along a portion thereof comprising an electrically conductive surface to be placed in contact with tissue to be ablated. Additionally, the epicardial lead includes an integral fastener disposed proximate a distal end thereof and a sliding lock collar having an aperture therein through which said epicardial lead passes. A complementary fastener may be secured thereto for engaging the fastener of said epicardial lead, thereby securing said lead in place around tissue to be ablated. The apparatus further includes an endocardial ablating lead placed in the left atrial chamber via transfemoral insertion for conduction of radio frequency energy between the ablating lead and the ablating surface of the epicardial lead.
