Cryoballoon ablation for atrial fibrillation guided by real-time three-dimensional transoesophageal echocardiography: a feasibility study

Abstract

Cryoballoon ablation is safe and feasible under RT 3D TEE guidance. This imaging tool permits perfect visualization of all PV ostia and neighbouring LA structures. Most importantly, it proved very efficient in guiding the operator to achieve complete occlusion and successful isolation in all veins.
