Nettet21. jan. 2024 · This process progressively causes a reduction in aortic valve area, resulting in progressive stenosis 1,2. This stenosis causes a left ventricular outflow tract (LVOT) obstruction. The turbulent blood flow from this LVOT obstruction explains the timing of the murmur and the various peripheral signs associated with aortic stenosis 1,2. Nettet23. nov. 2024 · The presentation relies on the degree of right ventricular outflow tract obstruction (RVOTO). Typically this is significant, resulting in cyanosis evident in the neonatal period, as a consequence of the right … Nettet3. jul. 2024 · Left ventricular outflow tract velocity time integral (LVOT VTI) is a measure of cardiac systolic function and cardiac output. Heart failure patients with low cardiac output are known to have poor cardiovascular outcomes. Thus, extremely low LVOT VTI may predict heart failure patients at highest risk for mortality.
