Application progresses of new cardiovascular MR techniques on valvular heart disease / 中国医学影像技术

ABSTRACT

Valvular heart disease (VHD) is one kind of the main causes of cardiovascular events in the elderly patients. Cardiac imaging evaluation plays a critical role in the diagnosis and selection of treatment options for VHD. New cardiovascular MR (CMR) techniques have been increasingly used for VHD patients, of which 4D Flow MRI-derived hemodynamic parameters can be used to estimate transvalvular blood flow velocities, pressure gradients, wall shear stress and flow patterns, T1 mapping and extracellular volume fraction enable quantification of changes of early ventricular remodeling secondary to VHD, strain analysis can be used to assess early myocardial dysfunction. The application progresses of new CMR techniques on VHD were reviewed in this article.
