Mitral Stenosis Clinical Trial
Official title:
Assessment of Right Ventricular Function in Patient With Severe Mitral Stenosis Before and After Balloon Mitral Valvuloplasty
To detect short-term impacts of successful balloon mitral valvuloplasty on right ventricular function
In patients with mitral valve stenosis, right ventricular failure may develop either by the rheumatic process directly or through hemodynamic alterations resulting from pulmonary vascular changes. Right ventricular (RV) function plays an important role in development of clinical symptoms and prognosis in patients with mitral stenosis (MS).This is primarily affected by hemodynamic effects on RV due to pulmonary hypertension(PH). In the last two decades, Percutaneous Transluminal Mitral Commissurotomy (PTMC) has become the treatment of choice for patients with symptomatic rheumatic MS . Using this method,Mitral Valve Area (MVA) can be increased, which can improve the hemodynamic and clinical features of patients with MS . RV functional assessment is difficult and not done routinely because of its complex anatomy and high load dependence. Different modalitis are used to assess RV function as Tissue Doppler and two-dimensional (2D) speckle tracking method has been used to quantify strain for assessment Myocardial strain is a measure of tissue deformation, which is expressed as a percentage change. ;
