Reduction in pulmonary artery pressures on right heart cath after percutaneous transmitral commissurotomy.

Abstract

Objectives: To find out the reduction in pulmonary artery pressures on right heart Cath after percutaneous trans mitral commissurotomy. Study Design: Cross-sectional Observational study. Setting: Catheterization Lab Faisalabad Institute of Cardiology, Faisalabad. Period: April 2022 till October 2022. Material & Methods: After approval from hospital ethical committee 67 patients of severe mitral stenosis having pliable valve suitable for PTMC on TTE followed by TEE to exclude its contraindications and then finalized for PTMC procedure were enrolled in study after informed consent. PTMC was performed through femoral route using INNOUE balloon. Pre PTMC and post PTMC Right ventricle pressures were measured on table in cath lab. Results: Mean age was 33.8 ± 8.4 with 28.4% (n=19) were male, 71.6% (n=48) were females. 79 % patients had NYHA III symptoms of dyspnea. Mean LA diameter was 50.4mm and mean MVA was 1.02 cm². 65.7% patients had A.fib before PTMC. Others were in sinus rhythm. Majority of patients had severe pulmonary hypertension before PTMC which had significant reduction (mean 23mmHg) in catheterization lab 10 minutes after PTMC procedure. Conclusion: PTMC is quite effective procedure with significant reduction of not only LA pressure but also of right ventricle indicating its effectiveness from the day of procedure.
