Abstract

Objective: To know regression of ECG changes after successful percutaneousmitral commissurotomy (PTMC) for severe isolated mitral stenosis patients.

Methodology: This cross sectional study was conducted from 1st Feburary 2016to 31 August 2016 (06 months) in National Institute of Cardiovascular Diseases,Karachi - Pakistan. All consecutive patients admitted for PTMC for severe isolatedmitral stenosis were subjected to detailed transthoracic echocardiogram (TTE)and 12 leads ECG before and after procedure as per protocol. All the data wereanalyzed by SPSS Version 19.0.

Result: Among total of 99 study population, females were 65(65.7%). Mean agewas 27.44±6.26 years. Standard 12 lead ECG showed P wave amplitude of 0.26± 0.0491 mV pre PTMC versus 0.24±0.036 mV post PTMC (p <0.001). Pwave duration in V1/V2 (greater of these two chest leads) was 114.32msec ±11.94 msec (80-140msec) and 108.64msec±14.55 (80-140msec) pre andpost PTMC respectively (p <0.001). R wave amplitude in V1/V2 (greater of thetwo) 0.2879±. 2031 mV vs. 0.2313±.1475mV pre and post PTMC respectively(p <0.001). Axis of the heart was 88.28±19.51 degree (45-120) pre PTMC vs.84.34±19.79 degrees (30-120) post PTMC respectively. RV hypertrophy asdemonstrated by R wave in V1 plus S wave in V5 was 0.4830± .2239 millivolt vs.0.3980±.1823 millivolt (p <0.001) pre PTMC& post PTMC respectively.

Conclusion: Successful PTMC procedure causes significant regression ofquantitative ECG changes in isolated mitral stenosis patients in mid-term followup.
