1989) reported that coronary arteries develop through ingrowth of the vessels by demonstrating that the coronary arteries could be identified in the walls of the aortic sinuses
before the formation of the coronary orifices.
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 aneurysm, dilatation of one or more of the aortic sinuses
, is a rare but important aortic root defect, which can be a cause of some serious cardiac sequels.
1] The aortic sinuses
reach beyond the upper border of the cusp and form a well-defined, complete, and circumferential sinutubular ridge when viewed from the aortic aspect.
Indeed, through 1965, only fifteen cases of MA of the aortic sinuses
and ascending aorta had been reported, with sporadic case reports since then .
The aortic sinuses
and coronary orifices looked normal.
Results: Both coronary arteries arose from the aortic sinuses
below the supravalvular ridge in all the cases.
The coronary arteries arise from two of the three aortic sinuses
or sinuses of Valsalva present at the root of ascending aorta.
Surgical treatment for aneurysms of the aortic sinuses
with aorticoatrial fistula; experimental and clinical study.
These sinuses are named according to their position as the anterior, left posterior, and right posterior aortic sinuses
The sizes (height and width) of the three aortic sinuses
at the level of the sinotubular junction were measured (Fig.
INTRODUCTION: The right and left coronary arteries arise from the ascending aorta in its anterior and left posterior aortic sinuses
