Aortic Root Replacement for Pseudoaneurysm Arising from Freestyle Aortic Bioprosthesis.

چکیده
A 70-year-old female presented with a new systolic murmur and shortness of breath three years after undergoing aortic root replacement using a 27-mm Medtronic Freestyle® stentless full root bioprosthesis (Medtronic, Inc., Fridley, Minnesota, USA). A large complex aortic root pseudoaneurysm was identified on contrasted computed tomography of the chest and transesophageal echocardiogram. We describe the redo aortic root replacement using a customized Dacron tube/valve composite graft with a proximal "skirt" and a modified Cabrol technique.

Structural Valve Deterioration After Aortic Valve Replacement with Medtronic Freestyle Stentless Porcine Aortic Root Bioprostheses
The Medtronic freestyle aortic root bioprosthesis (Medtronic, Inc., Minneapolis, MN, USA) is a stentless valve with an effective orifice area that is larger than that observed on other bioprostheses. However, there have been sporadic reports of structural valve deterioration (SVD), such as aortic root wall rupture, leaflet tearing, and pseudoaneurysm formation. We report five cases of SVD of fr...
متن کاملLong-term clinical outcomes 15 years after aortic valve replacement with the Freestyle stentless aortic bioprosthesis.
BACKGROUND The Freestyle stentless aortic root bioprosthesis has excellent hemodynamics and durability through 10 years. The purpose of this report is to present clinical outcomes in a large multicenter cohort through 15 years. METHODS The multicenter evaluation of the Freestyle valve began in 1992 at 21 centers in North America and Europe. In 1997, a long-term study continued, including 725 ...
متن کاملStructural deterioration of the Freestyle aortic valve: mode of presentation and mechanisms.
BACKGROUND Structural valve deterioration is the major cause of bioprosthetic valve failure. Because of the unique design features and anti-calcification treatment of the Freestyle (Medtronic Inc, Minneapolis, Minn) stentless bioprosthesis, development of structural valve deterioration may differ in comparison with other bioprosthetic valves. This study evaluates the mechanisms and clinical pre...
متن کاملLong-term clinical and echocardiographic follow-up of the Freestyle stentless aortic bioprosthesis.
BACKGROUND Stentless aortic bioprostheses were designed to provide enhanced hemodynamic performance and potentially greater longevity. The present report describes the outcomes of patients with the Freestyle stentless bioprosthesis followed for ≤18 years. METHODS AND RESULTS Between 1993 and 2011, 430 patients underwent primary aortic valve replacement with a Freestyle bioprosthesis in the su...
متن کاملBioprosthetic valve durability after stentless aortic valve replacement: the effect of implantation technique.
BACKGROUND The Freestyle stentless bioprosthesis (FSB) (Medtronic Inc, Minneapolis, MN) is implanted using 2 techniques-subcoronary or aortic root replacement. Our objective was to determine whether the implantation technique had an impact on late reoperation for structural valve deterioration (SVD). METHODS Between 1993 and 2013, 531 patients underwent aortic valve replacement (AVR) or aorti...
