Due to the increased resistance from the LV outflow tract obstruction, the LV pressure is increased during ejection There is an increase in end-systolic volume and right shift of the...
How is the LV pressure-volume loop affected in aortic stenosis? As the valve area narrows it poses significant obstruction to blood flow from the left ventricle: Normal valve area is 2.6– 3.5 cm2 in adults Haemodynamically significant obstruction occurs as the valve...
