Abstract
LEFT VENTRICULAR (LV) venting cannulae are used commonly during open-chamber cardiac surgical procedures to help evacuate retained air and debris after closure of the heart chambers. In this report, the authors describe a case of iatrogenic pulmonary vein stenosis (PVS) secondary to vent insertion site suture closure. Timely echocardiographic diagnosis allowed for immediate revision of the vent insertion site closure suture and return of normal pulmonary venous flow into the left atrium. Pulmonary vein stenosis is a known complication of orthotopic lung transplantation and transcatheter ablation for atrial fibrillation,1-4 and has been reported as a postoperative finding in patients undergoing open-chamber cardiac surgery with LV venting via the right superior pulmonary vein.
