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.
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.
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 ...
Mitral annular calcification (MAC) is a multifactorial chronic degenerative process in which calcium with lipid is deposited in the annular fibrosa ring of the heart's mitral valve. MAC was first discovered and described in 1908 by M. Bonninger in the journal Deutsche Medizinische Wochenschrift . [ 1 ]
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.
The normal diameter of the mitral annulus is 2.7 to 3.5 centimetres (1.1 to 1.4 in), and the circumference is 8 to 9 centimetres (3.1 to 3.5 in). Microscopically, there is no evidence of an annular structure anteriorly, where the mitral valve leaflet is contiguous with the posterior aortic root. [12]
