متن کاملHuge 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...

patient-year), major bleeding events (1.0%/patient-year), and aortic valve reoperation (0.26%/patient-year). They also reported that valve-related death was the most common cause of death (26.8%) and that the rates of freedom from valve-related death were 96.2%, 92.7%, 88.8%, and 86.6% at 5, 10, 15, and 20 years, respectively. These results compare favorably with the findings of previous report...
متن کاملRecurrent pannus formation causing prosthetic aortic valve dysfunction: Is excision without valve re-replacement applicable?
Prosthetic valve dysfunction at aortic position is commonly caused by pannus formation. The exact etiology is not known. It arises from ventricular aspect of the prosthesis encroaching its leaflets causing stenosis or it may remain localized causing left ventricular outflow tract obstruction without affecting valve function.The difference in location entails different approaches in management. ...
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...
