Frequency of Acute Mitral Regurgitation in Post Percutaneous Transvenous Mitral Commissurotomy Patients With Severe Mitral Stenosis

Abstract

Objectives: To determine the frequency of Acute Mitral Regurgitation in Post Percutaneous Transvenous Mitral Commissurotomy (PTMC) patients with severe mitral stenosis (MS). Methodology: A cross-sectional study was conducted at the Tabba Heart Institute, Karachi, Pakistan between September 2019 and April 2021. All patients irrespective of gender, aged between 19-80 years, and those who did not undergo PTMC were eligible to partake in the study. Patients with mitral regurgitation along with mitral stenosis, or those with clot in left atrium, or those suffering with the last stage of renal disease were excluded from the study. A predefined Proforma was used as a research instrument through which medical records of patients of PTMC are collected. The variables of the Proforma include patient’s age, name, sex, echo findings, treatment procedure, post-procedure data and complications. Results: A mean age of 40.6 ± 12.63 years was reported. 86 (81.9%) of the patients developed ‘no complications’, 15 (14.3%) of the PTMC patients suffered from ‘severe mitral regurgitation’, 2 (1.9%) had local hematoma, and one patient had a cardiac tamponade after the procedure. Only one patient died post-procedure. Post-stratification analysis showed that the majority of the female patients and 83% of the patients with no previous commissurotomy history did not have any complications. While a total of 14.7% who had no history of previous commissurotomy suffered from severe MR. Conclusion: Our study revealed that only a small number of patients who underwent PTMC suffered from severe mitral regurgitation. Overall, the procedure is safe with a good outcome.

Frequency of Acute Mitral Regurgitation in Post Percutaneous Transvenous Mitral Commissurotomy (PTMC) Patients with Severe Mitrall Stenosis (MS)

“…Results of our study was ompairable to the previous studies. [19,20] A small percentage of patients experienced complications, however the most prevalent was mitral regurgitation. Local site hematoma, cardiac tamponade, and mortality were all reported in the trial.…”
