Key result
Tri-technologies mechanical valve thrombosis and leaflet escape trigger massive MR and cardiogenic shock.
Why the study?
Acute prosthetic valve dysfunction due to leaflet escape is a rare mode of mechanical valve failure associated with high mortality that requires clinical awareness.
Case Report (n=1)
Highlights a rare but life-threatening complication of leaflet escape and thrombosis in a Tri-technologies bileaflet mechanical valve following anticoagulation discontinuation.

Alerts clinicians to leaflet escape risk after anticoagulation cessation; leaves open optimal surveillance strategies for mechanical valves.
Acute prosthetic valve dysfunction due to leaflet escape is a mode of structural valve failure of mechanical prostheses which is associated with a high mortality. In this report, we describe the case of a 32-year-old patient, who underwent mitral valve replacement with a Tri-technologies bileaflet valve three years ago, and was admitted to the hospital on August 2005, in cardiogenic shock. He discontinued oral anticoagulation therapy four months ago. Transthoracic and transesophageal echocardiograms showed acute-onset massive mitral regurgitation with normal left ventricular function. The patient underwent emergency surgery, during which one leaflet was found to be absent and the other leaflet was fixed due to prosthetic thrombus.

CIANCIULLI et al. (2006) conducted a case report in Acute mitral valve dysfunction (n=1). Tri-technologies bileaflet mechanical valve was evaluated on Acute-onset massive mitral regurgitation and cardiogenic shock. A 32-year-old man developed cardiogenic shock and massive mitral regurgitation due to leaflet escape and prosthetic thrombus in a Tri-technologies bileaflet mechanical valve.
