Huge pannus formation on a mechanical bileaflet mitral valve prosthesis 23 years after a third operation on the mitral valve.
Supplementary material (Videos 1 and 2) is available at EJCTS online. Video 1: Transoesophageal echocardiography showing a blockade of one of the leaflets of the mitral valve prosthesis due to a giant pannus formation with a resulting stenosis and insufficiency. Video 2: Fluoroscopy of aortic valve (top) and mitral valve (bottom) prostheses. There is an almost normal motion amplitude of one lea...
متن کاملLeaflet Escape in a New Bileaflet Mechanical Valve
Background—Leaflet escape is a mode of structural valve failure for mechanical prostheses. This complication previously has been reported for both monoleaflet and bileaflet valve models. We report 2 leaflet escape occurrences observed in 2 patients who underwent valve replacement with a TRI Technologies valve prosthesis. Methods and Results—At the University of Padua, between November 2000 and ...

متن کاملStructural analysis of a bileaflet mechanical heart valve prosthesis with curved leaflet
Structural analysis, especially the thickness effect on the structural strength, of a bileaflet mechanical heart valve prosthesis with curved leaflets is presented in this paper. Taking the wide variations of the blood flow pressure on the leaflet surface, the structural stresses inside the leaflet and deflections of the leaflet are investigated by adopting both linear and nonlinear structural ...
متن کاملAn unusual complication after chordal sparing mitral valve replacement.
Clinical Summary A 44-year-old man with cardiac failure was admitted to our clinic for increasing dyspnea. Transesophageal echocardiography showed severe mitral regurgitation with a prolapse of the anterior leaflet. Aortic regurgitation was referred to as mild. End-diastolic diameter was 73 mm, end-systolic diameter was 47 mm, and ejection fraction was calculated to be 0.50. Catheterization rev...
