[Apico-aortic conduit for severe aortic stenosis in elderly].
We described a case of an 84-year-old woman with end stage aortic stenosis in whom favorable results were obtained after constructing apico-aortic conduit bypass. The patient admitted due to complete atrio ventricular(AV) block and respiratory insufficiency. Although a permanent pacemaker was implanted, heart failure did not improve. Echocardiograms showed small aortic annulus and severe calcific aortic stenosis with a measured trans valve gradient of 100 mmHg. Since cardiac failure deteriorated and she lapsed into hypotension and acute renal failure, an emergency operation was performed. The left lateral thoracotomy was performed with cardiopulmonary bypass. A bioprosthetic valved conduit was anastmosed to the left ventricle apex. Another graft was anastomosed to the discending thoracic aorta. The operation was completed by anastomosing the tailored ends of the grafts together. Although the patient required hemodialysis for 2 weeks after operation, she was discharged on 57th day after operation without any complications. Apico-aortic conduit is considered to be an useful procedure for elderly patients who were not good candidates for conventional valve replacement.
