Endovascular Repair of an Aortic Arch Aneurysm with Triple Chimney Stent Grafts: A Case Report.

The treatment of an aortic arch aneurysm in high-risk individuals poses a significant challenge. We present a surgical patient with a patent left internal mammary artery (LIMA) graft and a large aortic arch aneurysm who underwent aortic stent-graft implantation and complete endovascular branching to preserve the LIMA inflow, with successful exclusion of the aneurysm. A moderate flow, proximal type I endoleak was observed after deployment that disappeared at 2-year follow-up.

Transcatheter aortic valve implantation without balloon predilation: a single-center pilot experience.

Aim: To assess the results of transcatheter aortic valve implantation (TAVI) using the Medtronic CoreValve prosthesis (Medtronic, Minneapolis, MN), without balloon predilation, in high-risk patients with degenerated severe aortic stenosis.

Methods And Results: Fifty-one consecutive patients who underwent direct TAVI, 98% through a transfemoral approach. Patients were 79 ± 8 years of age, 74% in New York Heart Association classes III or IV and at high risk for surgical valve replacement (mean logistic EuroScore 20 ± 15).
