Popis: | Results Out of 34 patients, 20 (58.8%) were males and 14 (41.2%) were females. Mean age of the patients was 37.82 ± 15.8 years. The mean left ventricular end diastolic dimension (LVED/BSA) was reduced by 2.11 from pre to postoperative (32.52 to 30.41, respectively; p < 0.0001). The mean LVMI was reduced by 31.86 gm from pre to postoperative (174.15 to 142.3 gm, respectively; p < 0.0001). the mean decrease of left ventricular mass index was 38.2 ± 5.4 gm/m2 in patients received valve size 25; was 33.833 ± 12.1 gm/m2 in patients received valve size 23; was 29.875 ± 8.425 gm/m2 in patients received valve size 21, and was 23 ± 19.621 gm/m2, in patients received valve size 19. The mean trans-aortic peak gradient was reduced by 41.36 from pre to post-operative (72.12 to 30.76, respectively; p < 0.0001). The mean decrease of the transaortic peak gradient was 48.8 ± 5.263 mmHg in patients received valve size 25 versus 33.286 ± 17.414 mmHg in patients received valve size 19. The mean ejection fraction (%) was increased by 6.45 from pre to postoperative (54.26 to 60.71, respectively; p < 0.0001). |
