KEY CLINICAL MESSAGE We describe the first valve-in-valve Corevalve transcatheter aortic valve replacement in the St. Jude Toronto stentless porcine aortic valve in the United States, which enabled this 59-year-old patient with a history of bacterial endocarditis and aortic regurgitation to avoid heart transplant with complete resolution of his severe left ventricular dysfunction.

To evaluate possible causes of discrepancy between Doppler and catheter gradients across prosthetic valves, five sizes (19-27 mm) of St. Jude and Hancock valves were studied in an aortic pulsatile flow model. Catheter gradients at multiple sites distal to the valve were compared with simultaneously obtained Doppler gradients. In the St. Jude valve, significant differences between Doppler and ca...

Abstract A 58-year-old male patient with degenerated St. Jude Epic mitral bioprosthesis underwent successful valve replacement using 29 mm Medical mechanical prosthesis. Case history presented here to prevent organ injury via a transeptal approach for epic bioprosthesis.

https://e-kcj.org A 40-year-old male was admitted to the cardiac care unit (CCU) due to severe pneumonia associated with unstable hemodynamics. Meanwhile, a grade 3–4 systolic murmur was heard at the left lower sternal border. Tracing his history back, he had undergone mitral valve replacement with a Björk-Shiley convexoconcave prosthetic valve (single tilting disc mechanical valve) 25 years be...

BACKGROUND The effective orifice area (EOA) of a prosthetic valve is superior to transvalvular gradients as a measure of valve function, but measurement of mitral prosthesis EOA has not been reliable. METHODS AND RESULTS In vitro flow across St Jude valves was calculated by hemispheric proximal isovelocity surface area (PISA) and segment-of-spheroid (SOS) methods. For steady and pulsatile con...

The aortic root was enlarged and a St Jude Medical valve obliquely inserted in 11 patients. Prosthetic valve sizes at least one, but often two, sizes larger than that which would normally be accommodated by the dimensions of the host aortic annulus were used. Closure of the valve was not affected by obliquity. This simple technique is recommended whenever the host aortic annulus does not allow ...

BACKGROUND We evaluated all adult St. Jude mechanical valve recipients at our institution since the initial implant in January 1979 and now present our 25-year experience. METHODS Nine hundred forty-five valve recipients were followed prospectively at 12-month intervals from January 1979 to December 2007. RESULTS Operative mortality was 3% in the aortic valve recipients and 5% in the mitral...
