Isolated huge aneurysm of the left main coronary artery in a 22-year-old patient with type 1 neurofibromatosis.

A 22-year-old patient with neurofibromatosis type 1 presented with acute chest pain. A computed tomography scan and coronary angiography revealed a partially thrombosed huge aneurysm of the left main coronary artery. Despite medical treatment, the patient's angina recurred.

Long-term results of Freestyle stentless bioprosthesis in the aortic position: a single-center prospective cohort of 500 patients.

Objective: Stentless xenograft bioprostheses may be the future valve of choice for aortic valve replacement. The study aim was to investigate the long-term clinical outcome after aortic valve replacement with the Medtronic Freestyle bioprosthesis (Medtronic Inc, Minneapolis, Minn).

Methods: Between April 1997 and November 2004, a total of 500 patients (mean age, 74.

Eight-year results of Freestyle stentless bioprosthesis in the aortic position: a single-center study of 500 patients.

Background And Aim Of The Study: Stentless bioprostheses may be the future valve of choice for aortic valve replacement (AVR). The study aim was to investigate mid-term clinical outcome after AVR with the Medtronic Freestyle valve.

Methods: Between April 1997 and November 2004, a total of 500 patients (241 females, 259 males) was implanted with a Freestyle bioprosthesis for AVR, without population selection, by a single surgical team at the authors' institutions.
