Growth characteristics of the reconstructed aortic arch, which is comprised of both native aortic tissue and homograft, ha...
INTRODUCTION AND OBJECTIVES Patients with aortic valve disease and a dilated ascending aorta are usually treated with a composite graft comprising a valve and conduit. We review here the results of treatment with an aortic root homograft as a valid alternative. PATIENTS AND METHOD Twenty-two consecutive patients with a mean age of 64.8 (8.8) years were studied. Mean ascending aorta dilation w...
Of the many factors that may be significant in permitting successful homotransplantation of tissue and organs, there is little question that the genetic relationship of the donor to the recipient will always be of prime importance. In the laboratory animal, there are many methods of producing permanent or markedly prolonged survival of homografts when major histocompatibility gene loci are the ...
OBJECTIVE The aim of this study was to analyze the midterm clinical results of aortic valve replacement with cryopreserved homografts. MATERIALS AND METHODS Aortic valve replacement was performed in 40 patients with cryopreserved homograft. The indications were aortic valve endocarditis in 20 patients (50%), truncus arteriosus in 6 patients (15%), and re-stenosis or regurtitation after aortic...
A 44-year-old female presented with prosthetic valve endocarditis with periannular abscess involving the left coronary ostium. We describe cryopreserved aortic homograft root replacement with hemi-Cabrol reimplantation of the left coronary ostium using the long saphenous vein.
