James (1961) had described the origin of SANA directly from the aortic sinuses. [13] Interventional cardiologists must be aware of the presence of multiple ostia in anterior aortic sinuses before doing procedures like right ventriculotomy for ventricular septal defect or pulmonary stenosis.
Sinus of Valsalva (SOV) aneurysm is defined as either the dilatation of one or more of the aortic sinuses located between the aortic valve annulus and the sinotubular junction or a crescentic/tubular-shaped outpouching extending from the body or apex of a normally sized SOV (1-3).
