Implante de la prótesis Edwards Intuity Elite en cirugía plurivalvular y en cirugía de revascularización coronaria concomitante

Abstract

IntroductionConcomitant use of rapid deployment valves is not widespread. A EDWARDS INTUITY Elite valve replacement and concomitant mitral valve replacementent or coronary artery bypass grafting (CABG) were performed. Patients and methodsWe implanted 15 consecutive EDWARDS INTUITY Elite in patients with mitral valve replacement or concomitant CABG. Patients were divided in two groups: Intuity + mitral (8 patients), and Intuity + CC (7 patients). We registered aortic cross-clamp and cardio-pulmonary bypass (CPB) times, and ICU and Hospital length of stay. Two control groups were selected: control + mitral (43 consecutive patients submitted to multiple valve surgery) and control + CC group (48 consecutive patients with aortic replacement and concomitant CABG). Mean and peak intra-prosthesis gradients were calculated before discharge by means trans-thoracic echocardiogram. ResultsThere were no intraoperative complications. Cross-clamp times in Intuity + mitral and Intuity + CC groups were 84,3 ± 10,1 and 67,1 ± 20,7, significantly lower than control groups (117 ± 36,1 y 102,7 ± 27,3) respectively. CPB times in Intuity + mitral were 112 ± 11,6 significantly lower than control group (138,1 ± 43,7). No paravalvular leaks or prosthesis dysfunction were observed. Two patients death during the follow-up. ConclusionsEDWARDS INTUITY Elite prosthesis significantly reduces CPB and cross clamp time when used in multiple valve surgery and cross clamp time in patients with concomitant CABG. The implantation is safe and feasible, and the postoperative intra-prosthetic gradients are adequate.
