BackgroundReimplantation of the native, structurally intact aortic valve within a Dacron tube graft in patients with aortic root aneurysms corrects annular ectasia and dilatation of the sinotubular junction. The durability of this valve repair with respect to the increased mechanical stress on valve cusps has been discussed, is quite controversial, and is yet unknown.
Methods and ResultsFrom July 1993 to November 1998, a
replacement of the ascending aorta with a repair of the aortic valve
was performed in 75 patients (53 men and 22 women aged 50±19 years).
Twenty-one patients (28%) had Marfan syndrome, and 11 patients (15%)
had an aortic dissection, type Stanford A (6 acute, 5 chronic). In 17
patients (23%), concomitant replacement of the aortic arch was
necessary. Clinical and echocardiographic follow-up was
performed in 6- to 12-month intervals for a cumulative study period of
137 patient-years. No operative deaths occurred. Two patients (3%)
died 5 and 20 months postoperatively. One additional patient
experienced a transient ischemic attack within the first
postoperative week. Three patients (4%) with progressive aortic
insufficiency required aortic valve replacement after 9, 11, and 14
months. All other patients had no or mild aortic insufficiency. The
repairs have now remained stable for
65 months (mean, 22±20 months).
Other valve-related complications did not occur.
ConclusionsOur results demonstrate that this type of aortic valve repair achieves excellent results in selected patients. Perfect coaptation of valve cusps during the repair with no or only trace aortic insufficiency at initial echocardiography seems to be essential for durability.
