A ventricular outflow tract obstruction means there is a limitation in the blood flow out of either the right or left ventricles of the heart, depending on where the obstruction is.
A ventricular outflow tract is a portion of either the left ventricle or right ventricle of the heart through which blood passes in order to enter the great arteries. [1]The right ventricular outflow tract (RVOT) is an infundibular extension of the ventricular cavity that connects to the pulmonary artery.

The flow through the LVOT, or LV stroke volume (in cm 3), can be calculated by measuring the LVOT diameter (in cm), squaring that value, multiplying the value by 0.78540 (which is π/4) giving a cross sectional area of the LVOT (in cm 2) and multiplying that value by the LVOT VTI (in cm), measured on the spectral Doppler display using pulsed ...
Velocity Time Integral is a clinical Doppler ultrasound measurement of blood flow, equivalent to the area under the velocity time curve. The product of VTI (cm/stroke) and the cross sectional area of a valve (cm2) yields a stroke volume (cm3/stroke), which can be used to calculate cardiac output.
Let's unpack what makes a series take flight. A pilot is often the first episode of a new television series. Occasionally they will be presented as extra-long episodes, sometimes in the form of a ...
This all despite multiple expensive attempts over the years at some form of automation, the Post reported. As of 2014, multiple administrations had already spent at least $100 million over 30 ...
