Mitral stenosis was present in 28%, and the extent of calcification was associated with mean mitral valve gradient (P < .0001). MR was prevalent (present in 81%) but was severe in none. The severity of MAC was greater in patients with moderate MR than in those with no or mild MR (P = .04).

Web17 de out. de 2024 · The size of the valve was classically assumed to be fixed in the remodeling ventricle; however, the mitral valve (MV) can enlarge to adapt to ventricular expansion 17 – 21 and reduce MR. 18 Experimental studies have demonstrated that mechanical stretch induced by leaflet tethering can induce active valve growth. 19,22 …
WebConclusions: MVs that exhibit prolapse have higher strain compared to normal valves, particularly in the posterior leaflet. Although higher strain is observed with worsening MR and larger valves and annuli, mitral valve leaflet thickness-and, thus, underlying MV pathology-is the most significant independent determinant of valve deformation.
