Efficacy Of Percutaneous Transvenous Mitral Commisurotomy To Immediately Reduce Pulmonary Hypertension In Patients With Severe Rheumatic Mitral Stenosis

Abstract

Objective: In patients with severe rheumatic mitral stenosis, to ascertain the rate of the efficient percutaneous transvenous mitral commisurotomy (PTMC) for lowering lung pressure.

Materials and methods: In this study, a total of 196 patents were examined after receiving permission from the institutional ethical and scientific assessment committee. All of the patients who had signed up had thorough physical examinations and histories completed before undergoing transthoracic and transesophageal echocardiography. A technique utilising the right femoral bone was used to execute PTMC. Under local anesthetic, the Seldinger method was used to provide right femoral arterial and venous accesses. Inoue balloon was utilized in accordance with the patient's height.  Pulmonary artery pressure was measured in each patient during the procedure in cath lab (both in pre- and post-PTMC period). SPSS (version 23.0) was used to identify the impact modifiers, effectiveness was stratified based on age, gender, the length of severe rheumatic mitral stenosis, occupation, and socioeconomic level. A statistically significant outcome was determined using the post-stratification chi square test, with a P value of 0.05.

Results: The mean age in this research was 30 years, with an SD of 2.16.  Patients made up 68% of the population were female and 32% were male. Initial mean pulmonary artery pressure was 47.41±11.02 and final mean pulmonary artery pressure was 33.24±7.83. Furthermore, PTMC was successful in 85% of patients and unsuccessful in 15%.

Conclusion: In patients with severe rheumatic mitral stenosis, our research found that PTMC was 85% successful in lowering pulmonary artery pressure.
