- W2003269918 abstract "In the Heart Institute of University of São Paulo Medical School, between 1980 and 2000, were performed 712 mitral valve repair procedures, 39 aortic valve repairs and 469 tricuspid valve repairs. In our experience with mitral valve repair, the most performed techniques were quadrangular resection of the posterior leaflet, posterior annuloplasty with bovine pericardial sling and Carpentier ring annuloplasty. Quadrangular resection of the posterior leaflet is the technique of choice in mitral regurgitation due to degenerative disease, and repair is possible in 90% of the cases. Since 1994, we perform the quadrangular resection without ring annuloplasty, a modification in the technique called Double Teflon technique, with good results. Aortic valve repair is performed in specific situations. In congenital aortic insufficiency, we perform the suspention of the prolapsed leaflets in the comissures. In rheumatic aortic insufficiency, when we found leaflet retraction, we elongate the leaflets with bovine pericardial patchs. Our experience of aortic valve repair, between 1980 and 2000, consists of a small group of 39 patients. The results are satisfactory, but these techniques are feasible only in selected cases. Tricuspid insufficiency is generally a consequence of annular enlargement in patients with mitral valve disease and we prefer the De Vega annuloplasty in these cases. In cases with large annulus dilatation, we prefer to use the Revuelta or the bicuspidization techniques. In patients with previous tricuspid repair and annulus distortion, we prefer to use bovine pericardial sling or Carpentier ring annuloplasty." @default.
