Intermediate term results of isolated mitral valve replacement with glutaraldehyde-preserved porcine xenograft valve: clinical and hemodynamic comparison between Hancock valve and Angell-Shiley valve.
Clinical and hemodynamic assessments were carried out for 30 cases, who underwent isolated mitral valve replacement with glutaraldehyde-preserved porcine xenograft valve. The cases were divided into two groups, according to the types of prostheses. Group H comprised 23 cases with Hancock 342 valve and group AS, 7 cases with Angell-Shiley valve. Mean (S.D.) follow-up periods were 4.0 +/- 0.7 in ...
متن کاملHaemolysis after mitral valve replacement with the Björk-Shiley and the Lillehei-Kaster disc valve prosthesis.
The present study reports on the incidence and degree of intravascular haemolysis in 33 patients with Björk-Shiley tilting disc prosthesis and in 34 patients with Lillehei-Kaster pivoting disc valve prosthesis in the mitral position examined 12 to 24 months after the operation. Serum haptoglobin, serum lactate dehydrogenase, serum bilirubin, and haemoglobin estimations were performed. Significa...
متن کاملRight sided heart evaluation after successful mitral valve replacement.
Introduction: It is well-documented that right-sided heart dysfunction and significant tricuspid valve regurgitation (TVR) have adverse effects on patient outcomes after left-sided heart valve surgery. Therefore, the evaluation of right ventriclular (RV) function and TR severity in patients who had undergone mitral valve replacement (MVR), associated with/without concomitant su...
متن کاملStructural 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 کاملMidterm results after stentless mitral valve replacement.
BACKGROUND To analyze the midterm clinical results after stentless mitral valve (SMV) replacement. METHODS AND RESULTS Fifty one patients (68.3+/-8.4 years, 35 female) with severe mitral valve disease (stenosis 25, incompetence 17, mixed lesion 9) received a chordally supported SMV (Quattro, St. Jude Medical Inc.) since August 1997. Preoperative New York Heart Association class was 3.1+/-0.6;...
