Aortic valve replacement with pulmonary autograft in children and adults

Aortic valve replacement with a conventional prosthesis is still flawed with complications, especially in children and young adults. Complex aortic root enlargement (Konno) is often needed because of small aortic diameter. The poor compliance with anticoagulation by teenagers and the risks associated with this made us look at alternative techniques. From November 1990 to June 1994, 70 patients were considered for pulmonary autografts in our institution; 64 underwent the procedure with one death and one failure to implant. Short-term results are excellent, with minimal gradient in 90% and minimal regurgitation in 96% of the patients. The long-term follow-up, hopefully, will confirm the superiority of this procedure over more conventional replacement.
