A case of aortic valve replacement with St. Jude Medical Regent valve (first implant in Japan).
The St. Jude Medical (SJM) Regent valve was developed as a new mechanical valve by improving the conventional SJM valve. The effective orifice area is wider than that of Hemodynamic Plus (HP) series. The efficacy of the new valve has been reported in Europe and the United States. On October 26, 2004, we first performed aortic valve replacement (AVR) with the SJM Regent valve for aortic valve st...
متن کاملOn-X versus St Jude Medical Regent mechanical aortic valve prostheses: early haemodynamics
OBJECTIVE We aimed to compare the early haemodynamic data of the On-X and St Jude Medical (SJM) Regent bileaflet mechanical prostheses in the aortic position. METHODS A retrospective study was performed using data collected prospectively for a national database. Thirty-three patients who had aortic On-X valve (On-X group) and 33 matched patients who had aortic SJM Regent valve (SJM group) wer...
متن کاملSeventeen-millimeter St. Jude Medical Regent valve in patients with small aortic annulus: dose moderate prosthesis-patient mismatch matter?
BACKGROUND The study was designed to evaluate the effects of moderate prosthesis-patient mismatch (defined as 0.65 cm(2)/m(2) <indexed effective orifice area ≤ 0.85 cm(2)/m(2)) on midterm outcomes after isolated aortic valve replacement with a 17-mm St. Jude Medical Regent valve in a large series of patients, and to determine if these effects are influenced by patient confounding variables. M...
متن کاملEvaluation of 17-mm St. Jude Medical Regent prosthetic aortic heart valves by rest and dobutamine stress echocardiography
BACKGROUND The prosthesis used for aortic valve replacement in patients with small aortic root can be too small in relation to body size, thus showing high transvalvular gradients at rest and/or under stress conditions. This study was carried out to evaluate rest and Dobutamine stress echocardiography (DSE) hemodynamic response of 17-mm St. Jude Medical Regent (SJMR-17 mm) in relatively aged pa...
متن کاملThe St Jude Medical Trifecta aortic pericardial valve: results from a global, multicenter, prospective clinical study.
BACKGROUND The St Jude Medical Inc (St Paul, Minn) Trifecta valve is a novel aortic biological prosthesis that incorporates several design features, including a true supra-annular sewing cuff, a stent design that maximizes valve hemodynamics while minimizing leaflet stresses, and an ethanol-based anticalcification technology. This study establishes the safety and early clinical and hemodynamic ...
