Abstract
- Background and Aim of the Study: The study aim was to assess the risk of reoperation for patients with a failing stented tissue valve.<br />Methods: Between 1980 and 1999, 259 patients (118 males, 141 females; mean age 60.1+/-15.4 years) underwent redo valve replacement to replace a failing stented tissue valve. Of these patients, 94 (36.3%) underwent redo aortic valve replacement (AVR), 105 (40.5%) redo mitral valve replacement (MVR), and 60 (23.2%) redo aortic and mitral valve replacement (DVR). Twenty patients (7.7%) had previous coronary artery bypass grafting (CABG); further CABG were performed in 32 cases (12.4%). Preoperatively, 216 patients (83.3%) were in NYHA functional class III or IV.<br />Results: The early mortality was (6.5%; n = 17), including three patients who had AVR, five DVR, and nine MVR. A higher preoperative NHYA status (p <0.0004) and emergency surgery (p <0.0001) were significantly associated with an increased risk of operative death (univariate analysis). Age at surgery (p = 0.45), previous CABG (p = 0.45), position of the valve replaced (p = 0.2), type of implant (p = 0.06) and presence of coronary artery disease (p = 0.51) were not associated with a significant risk of operative mortality. Including those patients who died, 88 (34.0%) experienced a peri- or postoperative complication, seven of which (2.7%) were permanent.<br />Conclusion: A failing tissue valve can be replaced, with acceptable operative mortality and morbidity. The choice of valve is a balance of its advantages and disadvantages, and these must be discussed with the patient. It appears, however, that the trend towards reducing the age at which tissue valve implantation is performed may be justified.
