Abstract/OtherAbstract:
|
A 59 year old male was admitted 10 weeks following insertion of a Medtronic Hall mitral prosthesis. He suffered recurrent episodes of electromechanical dissociation (EMD). Transthoracic echocardiography demonstrated that during the times of haemodynamic compromise, the mitral prosthesis was intermittently obstructed. Emergency surgical intervention revealed that chordae tendineae had prolapsed through the lesser orifice, obstructing the valve mechanism. The mitral remnants were excised, and as the valve functioned normally, it was not replaced. Postoperatively, the patient made an uneventful recovery. This case illustrates the Doppler echocardiographic features associated with extrinsic obstruction of a mitral prosthesis, and demonstrates that this unusual complication can be responsible for late valve dysfunction. |
