Hemodynamic outcomes of geometric ring annuloplasty for aortic valve repair: A 4-center pilot trial
Original language description
Objectives: A geometric annuloplasty ring could improve efficacy and stability of aortic valve repair. Toward this goal, a 1-piece 3-dimensional titanium annuloplasty ring with Dacron covering was developed and tested successfully in animals. The purposeof this study was to define hemodynamic outcomes with this device used as the annuloplasty component of human aortic valve repair. Methods: In a 4-center pilot trial with informed consent, 16 patients underwent aortic valve repair for aortic insufficiency, with the annuloplasty device sutured into the annulus beneath the leaflets. Preoperative annular diameter averaged 26.5 +/- 2.0 (mean +/- standard deviation) mm, and average ring size was 22.3 +/- 1.2 mm. After annuloplasty, leaflet defects were easyto identify, and 14 of 16 patients (88%) required leaflet plication and/or autologous pericardial reconstruction for leaflet defects. Three patients had ascending aortic replacement, and 2 had remodeling root replacement. One had ultraso
