Successful Single-Stage Operation for Loeys-Dietz Syndrome With Critical Coarctation of the Descending Aorta in a Young Adult.

Patients with critical coarctation of the aorta complicated with Loeys-Dietz syndrome are extremely rare. We report a successful single-stage operation involving critical coarctation of the descending aorta with a bicuspid aortic valve, aneurysmal aortic root, and ascending aorta in a 19-year-old man. The patient was genetically evaluated and a novel heterozygous TGFBR2 mutation was detected.
