Objective: Abnormal right ventricular function plays an important role in
development of clinical symptoms and overall prognosis of patients with
mitral stenosis. Hemodynamic and radionuclide studies have demonstrated
long-term improvement in RV function after PTMC. However, exact quantification
by conventional echocardiographic technique is difficult owing to
complex 2D anatomy. This study evaluates the immediate and short term
follow up impact of successful percutaneous transvenous mitral valve
commissurotomy (PTMC) on RV function in patients with mitral stenosis
using 2D Echo and Doppler tissue imaging. Methods: 219 patients (mean
age 26 + 6yrs) with rheumatic MS, all in sinus rhythm were studied before
and 24-48 hrs after PTMC. Parameters of global and longitudinal RV function
were assessed by conventional 2D ECHO and Doppler tissue imaging.
Results: Immediately following PTMC, mitral valve area increased
from baseline of 0.71 ± 0.15 cm2 to 1.84 ± 0.17 cm2 (P 0.0001), RV outflow
tract fractional shortening (RVOT–FS) increased from 33.94 ± 7.55%
to 37.33 ± 7.67% (
PTMC, RV function, ECHO indices-2D and DTI, procedural outcome-immediate and short term.
