  • Title: Partial hammock valve: surgical repair in adulthood.
    Author: Aramendi JI, Rodríguez MA, Voces R, Pérez P, Rodrigo D.
    Journal: Ann Thorac Surg; 2006 Sep; 82(3):1103-6. PubMed ID: 16928552.
    Abstract:
    We describe a forme frustrée of hammock valve involving only the posterior mitral leaflet. Three adult patients were referred to surgery with the diagnosis of severe mitral regurgitation due to fibrosis of the posterior mitral leaflet. The final diagnosis was done intraoperatively. In all of them the posterior leaflet was attached to some accessory papillary muscles arranged en palisade, with three to four fused muscle heads producing restrictive leaflet motion in systole. Repair consisted in division of the papillary muscles, patch augmentation, and ring annuloplasty. This previously unreported lesion is congenital but manifests itself in adulthood.
