  • Title: Extrinsic mechanism obstructing the opening of a prosthetic mitral valve: an unusual case of suture entrapment.
    Author: Ozkan M, Astarcioglu MA, Karakoyun S, Balkanay M.
    Journal: Echocardiography; 2012 Feb; 29(2):E28-9. PubMed ID: 22067037.
    Abstract:
    Obstruction to a prosthetic cardiac valve is a well-recognized complication of cardiac valve replacement. Malfunction of the mobile component of a prosthetic valve to open or close correctly may occur in consequence of intrinsic or extrinsic causes (thrombus, vegetation, entrapment of left ventricular myocardium, suture entanglement, and pannus formation) that may result prosthetic valve stenosis and/or insufficiency. In the case we report a 48-year-old female with valve dysfunction occurred early after surgery, as one valve leaflet was only able to partially open due to suture entrapment.
