Hemodynamic Alterations Induced by Isoproterenol and Pacing After Aortic Valve Replacement with the Bjork-Shiley or St. Jude Medical Prosthesis
Stress evaluation was carried out in 26 patients approximately 7 months after aortic valve replacement with Bjork-Shiley valves (13 patients) and St. Jude medical valves (13 patients). During isoproterenol infusion (0.3 gg/kg/min), cardiac output increased by a factor of 1.5 and aortic valve area decreased by 50% for both valve groups, while transvalvular gradients (rest: 7 ± 2 vs 10 ± 5 mm Hg,...
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 کاملThe St. Jude Medical cardiac valve prosthesis: a 25-year experience with single valve replacement.
BACKGROUND From October 1977 to October 2002, 4,480 patients (age range, 17 to 94 years; average, 64 +/- 13 years) underwent single valve replacement with the St. Jude Medical heart valve. Of 2,982 aortic (AVR) and 1,498 mitral valve replacements (MVR), concomitant coronary artery bypass grafting was performed on 42% and 33%, respectively. METHODS Cardiac Surgical Associates has maintained an...
متن کاملTranscatheter aortic valve replacement with the St. Jude Medical Portico valve: first-in-human experience.
OBJECTIVES The purpose of this study was to demonstrate the feasibility and procedural outcomes with a new self-expanding and repositionable transcatheter heart valve. BACKGROUND Transcatheter aortic valve replacement is a viable option for selected patients with severe symptomatic aortic stenosis. However, suboptimal prosthesis positioning may contribute to paravalvular regurgitation, atriov...
متن کاملSevere haemolytic anaemia after replacement of the mitral valve by a St Jude medical prosthesis.
Severe haemolytic anaemia developed in a 33 year old patient after the mitral valve was replaced with a St Jude medical prosthesis. This was the patient's third thoracotomy. She had already had a mitral commissurotomy and a mitral valve bioprosthesis. The patient had an E+ antibody to red blood cells as well as a paraprosthetic leak. The haemolysis became less severe once the population of E+ r...
