An aortic valve-sparing operation for patients with aortic incompetence and aneurysm of the ascending aorta

J Thorac Cardiovasc Surg. 1992 Apr;103(4):617-21; discussion 622.


A number of patients who require an operation for complications of annuloaortic ectasia, such as aortic incompetence or aneurysm of the aortic root (or both), have normal aortic valve leaflets. We have treated these patients by excising the aneurysmal portion of the ascending aorta and sinuses of Valsalva but by leaving the aortic valve leaflets and some arterial wall attached to the left ventricular outflow tract. The aortic valve is reimplanted inside a collagen-impregnated tubular Dacron graft, similar to what is done for implantation of an aortic valve homograft. The coronary arteries are also reimplanted. This operation was performed in 10 patients. All patients had annuloaortic ectasia and five had the stigmata of Marfan syndrome. Four patients had acute aortic dissection. There were no operative deaths, but one patient required composite replacement of the aortic valve and ascending aorta because of persistent aortic incompetence. Postoperative Doppler echocardiography revealed normal aortic valve function in six patients and mild incompetence in three. The preliminary results of this new operation are encouraging. Further investigation is necessary to establish the best size, shape, and type of material that should be used to replace the aortic root while preserving the aortic valve.
