Abstract/OtherAbstract:
Aortic wall tears resulting from rupture of dilating balloons in infants undergoing transluminal balloon angioplasty have not been previously recognized. A 2 day old infant had percutaneous transluminal balloon angioplasty to dilate a stenotic aortic valve, and after multiple balloon inflations the balloon burst. The infant died 2 days after undergoing transluminal balloon angioplasty and at necropsy a circumferential, transverse aortic wall tear was found. To test the hypothesis that rupture of appropriately sized balloons results in similar aortic wall tears, six unfixed, intact infant aortas were subjected to transluminal balloon angioplasty at necropsy: two infants had balloon rupture with inflated balloon diameter similar to that of the aorta, two had balloon rupture with an undersized balloon and two had dilation with an oversized balloon. Transverse wall tears occurred in aortas with similar aortic and balloon diameters; no aortic wall damage occurred with rupture of undersized balloons, and aortic rupture resulted from the use of oversized balloons. Thus, intimal-medial tears in the infant aorta may result from balloon bursting during angioplasty when aortic and inflated balloon diameters are similar.
