OUTCOME OF PERCUTANEOUS MITRAL VALVE COMMISSUROTOMY ON MITRAL VALVE AREA , PULMONARY HYPERTENSION AND DYSPNEA CLASS

Abstract

Objective: To assess the effectiveness of Percutaneous Mitral valve Commissurotomy on mitral valve area pulmonary hypertension and NYHA dyspnea class in patients with mitral stenosis.

Study Design: Descriptive cross-sectional study.

Place and Duration of Study: Adult Cardiology departments of AFIC &NIHD from 1st January 2014 till 31st December, 2015.

Material and Methods: Seventy Three patients with severe mitral stenosis were included in the study that underwent PTMC using consecutive sampling technique. The procedural success of PTMC was noted by measuring mitral valve area through planimetry method by 2D Echocardiography in 24 hours after PTMC.

Results: There were 44 (60.3%) females and 29 (39.7%) males in the study, with mean age 35.75 ± 9.4 years. Mean NHYA dyspnea class of the patients before PTMC was 2.51 ± 0.7 and after PTMC mean NYHA Class became 1.34 ± 0.51. Mean pulmonary hypertension of the patients before PTMC was 52.45 ± 15.6mm Hg and after PTMC mean pulmonary hypertension was 44.58 ± 15.29mm Hg. Mean mitral valve area of the patients, before PTMC was 0.81 ± 0.19cm2 and after PTMC, mean mitral valve area became 1.52 ± 0.16 cm2. Paired samples t-test was used to assess the effectiveness of PTMC. The result was found to be statistical significant (p < 0.001) with respect to NYHA class of dyspnea, pulmonary hypertension and mitral valve area.

Conclusion: The procedural success of PTMC is high and it is a safe procedure as well. It should be offered to the patients with mitral stenosis who are filling the criteria for PTMC and unfit for surgery.
