Aortic Valve Stenosis - Physiopathology
Research News and Information
Definition of 'Aortic Valve Stenosis'A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA. Common names: Aortic Valve Stenosis; Aortic Valve Stenoses; Stenoses, Aortic Valve; Stenosis, Aortic Valve; Valve Stenoses, Aortic; Valve Stenosis, Aortic; Aortic Stenosis; Stenoses, Aortic; Stenosis, Aortic |

BACKGROUND: It is unclear whether small differences in transprosthetic gradient between porcine and bovine biologic aortic valves translate into improved regression of left ventricular (LV) hypertrophy after aortic valve replacement. We investigated ... Read more...
26 Sep 2009 BACKGROUND: Aortic stenosis in the midgestation fetus with a normal-sized or dilated left ventricle predictably progresses to hypoplastic left heart syndrome when associated with certain physiological findings. Prenatal balloon aortic valvuloplasty ... Read more...
6 Sep 2009 OBJECTIVES: This study was designed to examine the prognostic value of valvuloarterial impedance (Z(va)) in patients with aortic stenosis (AS). BACKGROUND: We previously showed that the Z(va) is superior to standard indexes of AS severity in ... Read more...
