Bioprosthetic Mitral Valve Regurgitation
The usefulness of two-dimensional color-Doppler flow-imaging (2D Doppler) in the detection, localization, and quantitation of bioprosthetic mitral valve regurgitation is uncertain. Mitral bioprostheses, before and after the creation of transvalvular (n = 33), paravalvular (n = 17), or combined (n = 23) defects, were mounted in a pulsed duplication system (flow rates, 2.5-6.5 1/min; pulse rate, ...
متن کاملThrombosed prosthetic mitral valve.
1 of 2 DESCRIPTION A 29-year-old woman presented with pulmonary oedema and low cardiac output. Her mitral valve was replaced 20 years back with a Sorin mechanical valve. She had stopped anticoagulants a month back on her own for excessive menstrual bleeding. Echo showed a gradient of 26 mm Hg across the valve with regurgitation. Fluroscopy confi rmed limited disc opening of only 15° with incomp...
متن کاملAcute thrombosis of bioprosthetic mitral valve
We report a case of acute thrombosis of bioprosthetic mitral valve in a 59 year-old Korean female, who underwent a mitral valve replacement with a 25 mm Carpentier - Edwards PERIMOUNT Plus bioprosthesis (Edwards Lifesciences, Inc.; Irvine, CA, USA) and a mini-Maze procedure for correction of mitral stenosis (MS) and atrial fibrillation (AF). On the 10th postoperative day, the patient began to c...
متن کاملProsthetic Mitral Valve Leaflet Escape
Leaflet escape of prosthetic valve is rare but potentially life threatening. It is essential to make timely diagnosis in order to avoid mortality. Transesophageal echocardiography and cinefluoroscopy is usually diagnostic and the location of the missing leaflet can be identified by computed tomography (CT). Emergent surgical correction is mandatory. We report a case of fractured escape of Edwar...
متن کاملthe impact of sub-valvular apparatus preservation on prosthetic valve dysfunction during mitral valve replacement
conclusions preservation of mitral annulus and papillary muscle continuity may enhance post- mvr cardiac performance with low mortality and morbidity rates. the risk of pvd was not significantly higher than conventional mvr in our series. results the improvement of functional status was seen in almost all survivors but was more obvious in the group i. in early follow-up, 56.4% of group i cases ...
