ABSTRACT
OBJECTIVE:
To present the immediate results and assess the clinical and hemodynamic performance of stentless bovine pericardial bioprostheses in aortic position.METHODS:
Twenty patients were operated who were indicated for surgery for valve replacement with biological prosthesis. Eleven patients were male; sixteen had aortic stenosis; four, insufficiency; the mean age was 66.3 +/- 8.8 years. The surgical technique used was subcoronary implant. Associated procedures were performed in five patients. Postoperative morbidity, mortality and hemodynamic performance were assessed on transthoracic echocardiogram.RESULTS:
Mean time of cardiopulmonary bypass was 136.5 +/- 24.41 minutes and mean anoxic time was 105.2 +/- 21.62 minutes. Hospital mortality was 5% (one patient). Mean time of intensive care unit stay was 3.65 +/- 3.23 days. Mean postoperatively transvalvular gradient was was 25.39 +/- 7.82 mmHg. Left ventricle ejection fraction was 67 +/- 13.49% preoperatively and 63.24 +/- 16.06% postoperatively (p = 0.45). Eleven patients did not present any degree of valve regurgitation, eight presented mild regurgitation and one ,mild to moderate regurgitation.CONCLUSION:
Stentless prostheses can be used for the surgical treatment of aortic valve diseases, with in hospital mortality and morbidity similar to the mortality and morbidity described in the literature for similar procedures, with satisfactory hemodynamic performance.
