The right coronary aortic valvar leaflet is retracted with a suture to demonstrate the dilated sinus of Valsalva. The aortic root in this case was poorly supported with a large membranous septum and no muscular support beneath the right coronary leaflet. Only the left coronary leaflet was supported by muscle (not shown). Note the left coronary orifice with its origin near the attachment of the left coronary leaflet at the sinutubular junction. In Image #2, the right atrioventricular junction is viewed anteriorly and in anatomic position. The aneurysm at the atrioventricular junction has been transected. The sectioned atrial myocardium and tricuspid valve demonstrate the close proximity of the aorta, atrioventricular and interventricular components of the membranous septum. The sinus of Valsalva aneurysm caused an ovoid, saccular dilation of the tricuspid valve hinge point that eventually perforated.
