摘要：Background: There is significant difference between the survival of patient with and without post-operative pulmonary arterial hypertension (PAH). This study was designed to see the early post-operative outcomes of PAH after preoperative oral administration of ambrisentan. Objective: Evaluation of role of preoperative oral ambrisentan for the management of PAH following cardiac surgery for ventricular septal defect (VSD) with moderate to severe PAH. Materials and Methods: A total of 54 patients were stratified into two equal groups (n=27) depeding upon receiving of orala mbisentan. Ambrisentan group received dose of 2.5mg and 5mg in two divided doses for weight 20 kg respectively at least two weeks before surgery. Results: PASP was measured peroperatively before establishment of CPB, immediately after VSD closure and after weaning from CPB which were 59.55±11.16 mm of Hg, 45.49±9.46 mm of Hg and 40.49 ±10.33 mm of Hg respectively in the ambrisentan group (Group-A) and was 71.92 ±10.62 mm of Hg, 66.34±10.22 mm of Hg and 62.14 ±9.46 mm of Hg respectively in the control group (Group-B) with a p value of 0.002, 0.001 and 0.001 respectively. Considering PASP on echocardiogram at 7th post-operative day was 33.55 ± 1.23 in ambrisentan group and 41.70 ± 5.60 in control group. At one month PASP on echocardiogram was 30.55±2.26 in ambrisentan group and 39.11 ±3.28 in control group. Conclusion: Preoperative oral administration of ambrisentan is more effective in control of postoperative PAH and may be advised in every patients with VSD with moderate to severe PAH.
