The current study was sought to assess the immediate effect of percutaneous balloonmitral valvuloplasty (PBMV) on right ventricular (RV) and pulmonary functions using speckle tracking echocardiography (STE) and spirometry respectively. Two-dimensional speckle tracking and doppler studies for strain and strain rate imaging of RV were performed before PBMV, after 48h and 15 days of PBMV using echocardiography and spirometry. Mitral valve area, peak and mean mitral valve transannular pressure gradients, late filling velocities,Wilkins score, Systolic pulmonary artery pressure, TAPSE, RV end-diastolic and end-systolic areas,RV fractional area change and Tei index were measured.
