OP Note: Following Arrest, we performed Pulmonary Vein Isolation. The heart as retracted to the right, the ligament of Marshal was incised and the left superior and inferior pulmonary veins were encircled. A medtronic cryoprobe was utilized to ablate the pulmonary veins for 2 minutes. Once the probe defrosted it was removed. The heart was then retracted to the left and the right superior and inferior pulmonary veins were encircled. The cryoprobe was again utilized to ablate pulmonary veins for 2 mins. Following this a 45mm atriclip was applied to the atrial appendage.
