Background:
Patients with aneurysms of the ascending aorta or aortic root may have associated aortic insufficiency (AI). We reviewed our experience with aortic root remodeling and reconstruction of the sino-tubular junction.
Methods:
Forty-five patients were operated on between July 1995 and September 1998. Transesophageal echocardiography showed AI grade III or IV in 15 patients. Twenty-seven patients had replacement of all three sinuses, 10 of one or two sinuses. Reconstruction of the sino-tubular junction alone was performed in 8 patients.
Results:
There was one death at 28 days. Perioperative transesophageal echocardiography showed no or discrete AI in all patients. There has been one aortic valve replacement at day 4 postoperatively for cusp repair failure. Transesophageal echocardiography in 40 patients at a mean time of 12.5 months showed no progression of AI in 38 patients, and a grade II in 2. Clinical follow-up averaged 14.5 months. There have been three late, not procedure-related deaths. Thirty-six patients are in New York Heart Association functional class I. There have been no cases of endocarditis.
Conclusions:
Aortic remodeling is successful in eliminating AI in patients with aortic root disease with minimal mortality and morbidity. Early echocardiography (1 year) has shown no progression of AI in 95% of cases.
