Aortic Stenosis and Systemic Hypertension, Modeling Of
Aortic stenosis (AS) is the most common cardiovascular disease after hypertension and coronary artery disease and is the most frequent cause of valvular replacement in developed countries (1,2). This disease refers to the narrowing of the aortic valve opening during left ventricular (LV) ejection (Fig. 1a). This can be caused by a congenital abnormality of the valve (for example, the valve coul...
متن کاملImpact of systemic hypertension on the assessment of aortic stenosis.
OBJECTIVE To determine the effect of systemic arterial hypertension on the indices of aortic stenosis (AS) severity. METHODS A severe supravalvar AS was created in 24 pigs. The maximum and mean pressure gradients across the stenosis were measured by Doppler echocardiography and by catheterisation. Both echocardiography and catheter data were used to calculate stenosis effective orifice area, ...
متن کاملSymptomatic aortic stenosis: does systemic hypertension play an additional role?
Hypertension and aortic stenosis represent 2 different models of left ventricular systolic overload. Previous studies have observed different remodeling patterns in these conditions. There is, however, little information about patients with coexisting aortic stenosis and hypertension. Echocardiography was performed in 193 consecutive patients with symptomatic aortic stenosis (113 males, 80 fema...
متن کاملRespective impacts of aortic stenosis and systemic hypertension on left ventricular hypertrophy.
It has been reported that 30-40% of patients with aortic stenosis are hypertensive. In such patients, the left ventricle faces a double (i.e. valvular and vascular) pressure overload, which results in subsequent wall volume hypertrophy. From a clinical standpoint, it is difficult to separate the respective contributions of aortic stenosis and systemic hypertension to left ventricular burden and...
