Use of the Medtronic Freestyle for aortic valve infection: A retrospective propensity score matched analysis.

Backgrounds: Aortic valve and prosthetic valve endocarditis present a challenging subgroup of patients at high risk. We analyzed our experience using the Medtronic Freestyle in full root technique for the treatment of these cases over 18-year time period.

Methods: We investigated the endocarditis subgroup from our cohort of 971 patients and compared results against other valve types with propensity score matching implementing nearest neighbor method.

Transfemoral stent-graft placement to treat a complication of the frozen elephant trunk procedure.

Purpose: To report a novel complication of a hybrid "frozen elephant trunk" endograft used in the treatment of a multisegmentally diseased aorta.

Case Report: A 53-year-old man with chronic type A aortic dissection and previous replacement of the supracoronary ascending aorta underwent a "frozen elephant trunk" procedure using a hybrid endograft. The stent-graft was placed deep in the descending aorta to cover the multiple distal re-entries.
