Percuteneous Trans-Mitral Commissurotomy (PTMC); Procedural Success and Immediate Results, an Experience from Tertiary Care Hospital in Northern Division of Bangladesh

Abstract

Background: One of the ultimate grave consequences of rheumatic heart disease is mitral stenosis. Percutaneous trans-mitral commissurotomy (PTMC) has been practiced with good results in the world since Inoue introduced it in 1982.

Objective: The aim of this study was to audit the procedural success, in- hospital outcome in patients undergoing PTMC in our set up. Study Design: Observational cross sectional study. Place and Duration: The study was conducted in northern division of Bangladesh with the collaboration of department of cardiology, Rangpur Medical College Hospital, Rangpur & Zia Heart Foundation, Dinazpur from February 2018 to November 2019.

Materials and Methods: Total Thirty patients who fulfill the inclusion and exclusion criteria for PTMC was enrolled in this study. Among them the procedural success & immediate results were assessed.

Results: Among 30 patients , 22(73.33%) were female and 8(26.66%) were male showing a female predominance. The mean age was 28.28±8.4.The procedure was successful in 29(96.66%) patients. In 1(3.3%) patient, we failed due to inability to puncture the septum for unfavourable anatomy. There was no mortality related to the procedure, no systemic embolization but one patient (3.33%) had significant MR(G II ). Pre PTMC mean MVA (cm2) was 0.801± 0.1325 and post PTMC it was 1.545± 0.292 cm2. Mean MVPG pre PTMC was 27.108±5.94 mmHg and post PTMC , 6.61±5.008 mmHg with significant p value 0.0001. Mean LA pressure before procedure was 28.65±8.456 mmHg and post PTMC, 11.27±6.34 and p value was 0.0001. Most of the patients 25(83.3%) before PTMC were in severe pulmonary hypertension and after PTMC most of the patients 21(70%) were in mild pulmonary hypertension.We successfully done 7 special cases like pregnancy, re do cases, H/O CVD etc.

Conclusions: We conclude that PTMC is a safe procedure in experienced hand with good success rate and optimal results even in patients with special problems like pregnancy, previous CVA and redo cases.
