ABSTRACT

Objective: To analyze the impact of PTMC on hemodynamic and anatomic outcomes.

Study Design: A descriptive observational study

Place and Duration of Study: This study was conducted at the Cardiology Department, Nishtar Medical University & Hospital Multan & CPE Institute of Cardiology, Multan from June 2020 to June 2021.

Materials and Methods: The study included fifty patients with isolated rheumatic mitral stenosis who underwent PTMC. The study included fifty patients with isolated rheumatic mitral stenosis who underwent PTMC. Mitral valve area, TMVG, and size of LA are measured in all patients through 2D transthoracic echo (with Toshiba Xario 2100). Echo was done before and 24 hours after PTMC. LA pressures before and after PTMC were measured in the
cath lab.

Results: The mean age of the subjects was 35.24±8.75 years. A number of male patients were 29 while that of females was 21. MV area before PTMC was .92±.087 cm2 which expanded to 1.68±.15 cm2 six weeks after PTMC. LA pressures after PTMC was also significantly reduced, it decreased from 25.8±7.4 mmHg before PTMC to 10.87±5.7 mmHg after it (p-value <0.001). Pulmonary artery systolic pressure and TMVG were also significantly reduced after PTMC.

Conclusion: For managing patients with rheumatic MS, PTMC is found to be effective and safe. It significantly improves hemodynamic and anatomic outcomes in these patients.

Key Words: Percutaneous transluminal mitral commissurotomy (PTMC), left atrial pressure, rheumatic mitral valve stenosis.
