In principle, the blood volume passing through a stenotic valve (aortic stenosis) is equal to the blood volume proximal to the stenosis or in the LVOT (Figure 4). The stroke volume is equal to ...

A new SWISS TAVI registry analysis provides some of the strongest evidence to date that the presence of left ventricular outflow tract (LVOT) calcification is a harbinger of worse outcomes in ...

A gene known to be important in cardiac development has been newly associated with congenital heart malformations that result in obstruction of the left ventricular outflow tract. A gene known to ...

WASHINGTON, DC—In patients undergoing transcatheter mitral valve replacement (TMVR), a balloon-assisted technique shows promise as a way of modifying the anterior mitral leaflet to prevent left ...

Left ventricular outflow tract (LVOT) obstruction, where blood flow from the left ventricle is limited and can lead to heart failure, is a significant complication of TMVR associated with high ...

In the dose-finding study, 10 weeks of treatment with aficamten brought resting left ventricular outflow tract (LVOT) gradients down significantly compared with placebo before a 2-week washout ...

The study included 41 patients at high risk of LVOT obstruction undergoing transseptal TMVR with balloon-assisted anterior mitral leaflet (AML) modification across 12 structural heart centers ...
