Figure 3. Pulmonary vein stenosis after balloon cryoablation. Cardiac computed tomography images (slab multiplanar reconstruction) before (A) and 8 months after (B) pulmonary vein isolation using a cryoablation balloon reveals moderate stenosis of the right superior, left superior, and left inferior pulmonary vein ostia. Middle panel images (left lateral view) and right panel images (right anterior oblique and caudal view) are volume-rendered virtual dissection images. LI: Left inferior pulmonary vein; LS: left superior pulmonary vein; RI: right inferior pulmonary vein; RS: right superior pulmonary vein.
