1. Nonstructural dysfunction of prosthetic heart valves
Nonstructural dysfunction of prosthetic heart valves. (A) Paravalvular leak adjacent to mitral valve prosthesis (arrow). (B) Tissue overgrowth compromising inflow orifice of porcine bioprosthesis. (C) Tissue overgrowth incorporating and resultant retraction and obliteration of bioprosthetic valve cusps. (D) Immobility of tilting disk leaflet by impingement of retained component of submitral apparatus (arrow) that had moved through orifice late following mitral valve replacement surgery. (E) Suture (arrow) looped around central strut of a Hall-Medtronic tilting disk valve causing disk immobility.
