Impact of mitral geometry and global afterload on improvement of mitral regurgitation after trans-catheter aortic valve implantation

Echo Research and Practice, 2016
Objective: To assess the impact of mitral geometry, left ventricular (LV) remodelling and global LV afterload on mitral regurgitation (MR) after trans-catheter aortic valve implantation (TAVI). Methods: In this study, 60 patients who underwent TAVI were

Diagnostic Value of Vena Contracta Area in the Quantification of Mitral Regurgitation Severity by Color Doppler 3D Echocardiography

, 2011
Background— Accurate quantification of mitral regurgitation (MR) is important for patient treatment and prognosis. Three-dimensional echocardiography allows for the direct measure of the regurgitant orifice area (ROA) by 3D ...

The influence of calcium-phosphate metabolism abnormalities on the quality of life in patients with hemodynamically significant mitral regurgitation

BMC Cardiovascular Disorders, 2019
Background In recent years, studies have indicated that vitamin D [25(OH)D3] and other calcium-phosphate (Ca-P) metabolism parameters and their disturbances might be potential new factors that may influence health-related quality of life (HRQoL). The aim
