CryoLife O'Brien aortic stentless prosthesis reoperations: clinical results and morphologic findings.
OBJECTIVES The CryoLife O'Brien (CLOB) stentless porcine aortic prosthesis has shown limited long-term durability, but its deterioration mechanisms have not yet been identified. The aim of this study was to review our experience with CLOB reoperations and to investigate the pathobiology of structural valve deterioration (SVD). METHODS Between March 1996 and December 2010, 35 patients underwen...
متن کاملEight-year results after aortic valve replacement with the CryoLife-O'Brien Stentless Aortic Porcine Bioprosthesis.
OBJECTIVE The long-term durability and hemodynamics of stentless valves are largely unknown. In this study we prospectively analyzed 8-year clinical results with the CryoLife-O'Brien Stentless Aortic Porcine Bioprosthesis (CryoLife Inc, Kennesaw, Ga) and assessed its hemodynamic performance by serial echocardiography. METHODS A total of 206 patients with a mean age of 72.8 years were followed...
متن کامل[Aortic valve replacement with a Cryolife O'Brien stentless bioprosthesis].
INTRODUCTION AND OBJECTIVES The Cryolife O'Brien xenograft is a stentless bioprosthesis constructed from noncoronary leaflets from three porcine aortic valves. The aim of this study was to investigate short-term results after aortic valve replacement with this composite xenograft. METHODS Since October 1993, Cryolife O'Brien bioprostheses have been implanted in 210 patients. The patients' mea...
متن کاملUsefulness of the Cryolife O'Brien stentless suprannular aortic valve to prevent prosthesis-patient mismatch in the small aortic root.
OBJECTIVES This study evaluated the occurrence of prosthesis-patient mismatch (PPM) after Cryolife O'Brien (CLOB) suprannular stentless valve replacement in patients with a small aortic root and its repercussions on the patient's hemodynamic status and left ventricular mass regression. BACKGROUND The correct management of the small aortic annulus is still controversial. Small aortic prosthese...
متن کامل[Surgical treatment of aortic valve disease with stentless bovine pericardium prosthesis: immediate results].
OBJECTIVE To present the immediate results and assess the clinical and hemodynamic performance of stentless bovine pericardial bioprostheses in aortic position. METHODS Twenty patients were operated who were indicated for surgery for valve replacement with biological prosthesis. Eleven patients were male; sixteen had aortic stenosis; four, insufficiency; the mean age was 66.3 +/- 8.8 years. T...
