Transseptal approach for pseudoaneurysms at the aortic root in Loeys-Dietz syndrome
Loeys-Dietz syndrome involves vascular abnormalities and aortic root aneurysms. This study described a 10-year-old boy who presented with progressively enlarging ascending aortic aneurysm and mild aortic valve regurgitation. He was diagnosed with Loeys-Dietz syndrome and underwent aortic valve-sparing repair. However, 6 months after the surgery, aortic root pseudoaneurysms were detected. Thus, aortic root repair was performed by transseptal approach. The orifices of pseudoaneurysms were closed...
