Question | Answer |
Tetralogy of Fallot (TOF) | congenital heart defect which is classically understood to involve four anatomical. abnormalities, although only three are always present |
Severe aortic stenosis (AS) | abnormal narrowing of the aortic valve opening |
Sever valvar aortic stenosis | Obstruction to outflow from the left ventricle by an abnormal aortic valve |
severe subvalvar aortic stenosis (SAS) | is a fixed form of anatomic obstruction to egress of blood across the left ventricular outflow tract (LVOT) |
severe supravalvar aortic stenosis | denotes obstructive constriction of the ascending aorta above the aortic valve |
severe subaortic stenosis | more severe form of LVOTO (Left ventricular outflow tract obstruction) that is often associated with aortic annular hypoplasia and valvular aortic stenosis. |
aortic regurgitation | heart valve disease in which the aortic valve weakens or balloons, preventing the valve from closing tightly. |
Aortico-left ventricular tunnel | (ALVT) extracardiac channel which connects the ascending aorta above the sinutubular junction to the cavity of the left or right ventricle. |
CHD Lesions on aortic valve and left ventricular obstruction | -severe aortic stenosis
-severe valvar aortic stenosis
-severe membranous subvalvar aortic stenosis
-severe subaortic stenosis, tunnel type
-severe supravalval aortic stenosis
-severe aortic regurgitation
-aortico-left ventricular tunnel |
