Abstract

Objectives: To study the long term clinical and echocardiographic outcomes of percutaneous Trans mitral balloon commissurotomy (PTMC) performed in patients with severe mitral stenosis.

Methodology: Total 103 patients were enrolled in this study. Their PTMC procedure was performed between the years 2015 to 2019. Those patients who returned for follow-up in the year 2021 were enrolled. At the time of follow-up their clinical and echocardiographic parameters were recorded.

Results: The mean age was 27.44±6.26 years and 97 (94.2%) of them were female. Mitral valve area was improved significantly, planimetry; 0.813±1.39 vs. 1.288±0.21cm2 and PHT; 0.871±0.13 vs. 1.336±0.19 cm2 between baseline and follow-up, respectively. Pressure gradient across mitral valve also improved 7.233±2.81 vs. 14.407±0.92 mmHg between baseline and follow-up, respectively. Pulmonary artery pressures were also reduced significantly 24±0.27 vs. 55±2.41 mmHg as well as the right ventricular systolic pressures 24.4±2.94 vs. 62.34±10.98 mmHg between baseline and follow-up, respectively. At follow-up, 70.9% had NYHA I class, 16.5% had NYHA II class, 11.7% had NYHA III class, and 1% had NYHA IV class compared to 6.8%, 5.8%, 33.9%, and 53.4% pre-procedure, respectively.

Conclusion: Long term follow-up of patients after PTMC showed satisfactory outcomes both clinically, as evident from improvement in NYHA functional class, and from echocardiographic stand point with sustained increase in mitral valve area over the period of years. Overall the results of PTMC performed in patients with severe mitral stenosis are satisfactory.
