Evaluation of the Effect of Percutaneous Ballon Mitral Valvuloplasty on Right Ventricular Function Using 2d Speckle Tracking Echocardiography

Abstract

Background; Mitral stenosis (MS) is a disabling and eventually lethal disease, The great majority of 
cases in adults are due to rheumatic heart disease. Right ventricular (RV) function plays an important 
role in development of clinical symptoms and prognosis in patients with MS.  Aim and objectives; 
We aimed to evaluate right  
ventricular  
functions  
by speckle tracking
echocardiography  in  patients  with severe  rheumatic  mitral  stenosis  before and  after  
percutaneous  mitral balloon  valvuloplasty, Subjects and methods; This was 
prospective study, was carried out in in Cardiology Department, national heart institute 
(NHI) and Benha university hospital on 100 patients with severe mitral stenosis who 
performed Percutaneous Balloon Mitral Valvuloplasty (PBMV). In our study we 
excluded patients with severe tricuspid regurge, patients who showed signs of 
concomitant aortic disease, patients with coronary artery disease,pericarditis and 
myocarditis.  All subjects were evaluated by history taking, clinical examination, 
routine laboratory investigations, 12-lead ECG, Conventional transthoracic 
echocardiography 2D echocardiography,
