“…This experience has shown that the operating surgeon is an important factor, as reported by others. [11][12][13][14][15][16]18,19 In this series, only associated mitral disease, especially mitral stenosis, precluded the use of a large prosthesis. The study on cadaveric hearts showed that the dimensions of aortic valves in the Indian population are similar to those of the Western population.…”

“…10 However, when the findings in group A are compared with published results, a higher proportion of these patients received a large prosthesis. [4][5][6][7][8][9][10][11][12][13][14][15][16] The mean aortic diameter (23.2 ± 1.9 mm) of Indian adult males corresponds to a St. Jude Medical aortic valve of 25 to 31 mm. Thus, the larger prostheses are closer to the size of the natural valve.…”

“…10 However, in most reported series, valves of these sizes were used infrequently, especially in patients with aortic stenosis. [11][12][13][14][15][16] This study was designed to analyze various factors that might influence selection of the size of prosthesis to be implanted.…”

A retrospective analysis was performed to determine the surgeon's impact on the selection of the size of prosthesis in aortic valve replacement. From January 1993 through December 1997, 748 patients underwent either isolated aortic valve replacement (530) or double valve replacement (218) with bileaflet valves. Depending on the operating surgeon, patients were divided into group A (367) or group B (381). Preoperative, intraoperative, and postoperative variables in both groups were compared. Groups A and B were identical in demographic and clinical profiles. Cardiopulmonary bypass time, ischemic time, and early and late results in both groups were similar. Significantly more patients undergoing isolated aortic valve replacement in group A (169; 67.9%) received a large (≥ 25 mm) prosthesis compared with group B (69; 24.5%). Compared with group B, a large prosthesis was used in a significantly greater proportion of all patients in group A, irrespective of etiology, predominant aortic valve lesion, and age of the patient. Overall, the operating surgeon was identified as the most important predictor (odds ratio 3.5; p < 0.0001) of use of a large valve.
