Coronary Button Pseudoaneurysms After Aortic Root Replacement in a Child With Loeys-Deitz Syndrome.

Loeys-Deitz syndrome (LDS) is a connective tissue disorder characterized by aggressive aortopathy with a proclivity for aortic aneurysmal rupture and dissection. Prophylactic surgical intervention is often indicated to ameliorate risk of aneurysm rupture. Aortic root replacement involves excision of the coronary arteries from the aortic root with a button of surrounding aortic tissue and subsequent anastomosis of these buttons to the synthetic aortic graft. We report the case of a 16-year-old girl with LDS who developed pseudoaneurysms at the sites of previous coronary button implantation.
