Cryoballoon ablation (CBA; Arctic Front, Medtronic) has proven very effective in achieving pulmonary vein isolation. Real-time three-dimensional transoesophageal echocardiography (RT 3D TEE) is a novel technology, which permits detailed visualization of cardiac structures in a 3D perspective. The aim of the present study was to assess the feasibility, advantages, and safety of RT 3D TEE in guiding CBA in a series of patients affected by paroxysmal atrial fibrillation. ⋯ 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.
