A method of surgical correction for patients with acquired aortic stenosis involving calcification of the aortic valve and the ascending aorta has been described. A prosthesis to a 21 mm biological valved conduit, interposed between the left ventricular apex and descending thoracic aorta, permits the left ventricle to bypass the obstruction and eject directly into the aorta. The pressure gradient across the aortic valve was decreased from 75 to 31 mmHg, with a 13 mmHg gradient between the left ventricle and the valved conduit. The patients remains assymptomatic four mounths after the operation, without fatigue or shortness of breath.
