Does balloon mitral valvuloplasty improve right ventricular strain and strain rate in patients with severe mitral stenosis?
Balloon mitral valvuloplasty improves impaired right ventricular strain in patients with severe mitral stenosis by reducing RV afterload.
RV systolic function is impaired in patients with severe MS and can be assessed by global and segmental RV strain before the appearance of clinical signs of systemic venous congestion. Impaired global and segmental RV strain values in these patients are primarily due to increased after load and improve after BMV with reduction in RV afterload.
