A 26.6-kg, intact, 9-mo-old female Göttingen minipig was presented for a coronary stent study. Angiography revealed a sinus of Valsalva aneurysm (SVA) in the aortic root that involved both the left and noncoronary sinuses of the heart. Gross histologic examination of the heart revealed 2 regions of aneurysmal formation: one at the ostium to the lef...

... histologic examination revealed 2 regions of aneu- rysmal formation: one at the ostium to the left main coronary artery, and the other at the dorsal aspect of the aortic root (Figure 2). The aortic root, with surrounding myocardium and the attached coronary arteries then were dissected from the heart (Figure 3).The dilation, located in the noncoronary (dor- sal) sinus of Valsalva, measured 0.9 cm in diameter. Sectioning revealed a mildly thin aortic wall. The left coronary sinus and ostium to the left main coronary were dilated (diameter, 1.0 cm), although the aortic wall and main coronary in the region did not grossly appear to be attenuated (Figure ...
