''BioGlue'' as a possible cause of acute blocked mechanical mitral valve leaflet.

A young patient with aortic and mitral valve infective endocarditis and advanced destruction of the surrounding tissues underwent a complex reconstructive surgery, including double valve replacement, reconstruction of aortic-mitral continuity and ascending aorta. Intraoperative transesophageal echocardiography revealed a blocked mitral leaflet, which was released by valve cleaning and reorientation. The application of biological glue may be a key point for this complication.
