Role of per-operative milrinone on pulmonary hypertension having mitral valve replacement.
Objective: To determine the role of perioperative milrinone on pulmonary hypertension in patients with mitral valve disease undergoing mitral valve replacement surgery. Study Design: Randomized Control Trial. Setting: Department of Cardiac Surgery, Faisalabad Institute of Cardiology, Faisalabad. Period: June 2019 to June 2020. Material & Methods: A total of 80 patients with mitral valve disease who underwent mitral valve replacement were included. The patients were divided into a control group of 40, who were not administered milrinone, and a study group of 40 who received milrinone perioperatively. TVPG, LVEF and NYHA class were recorded preoperatively and postoperatively and were compared. Results: In the study group, postoperative LVEFs and NYHA class were not statistically significant in both groups while postoperative TVPG was significantly lower in study group as compare to control group and is statistically significant (P<0.001). Conclusion: Our study concludes that milrinone can be used as an effective therapy to reduce pulmonary pressure in patients with pulmonary hypertension undergoing mitral valve replacement surgery.
