NettetPeak velocity, m/sec <2.5: 2.5-3: 3-4 >4: ... Subaortic obstruction implies that the stenosis is located in the LVOT (left ventricular outflow tract). Subvalvular stenosis is typically due to the presence of a subaortic membrane or HOCM (hypertrophic obstructive cardiomyopathy). NettetStenosis of the left ventricular outflow tract results in pressure overload of the left ventricle (Figure 12-6).The left ventricle responds to this chronic pressure overload by undergoing concentric hypertrophy. As blood is forced through the stenotic area, its velocity increases, resulting in turbulence, a systolic ejection murmur, and a post …
