title: Intermittent electromechanical dissociation as an unusual sign of prosthetic valve thrombosis in a patient with prosthetic fibrous ingrowth.
abstract: We describe the echocardiographic features of an unusual hemodynamic phenomenon of intermittent electromechanical dissociation during regular sinus tachycardia in a patient with prosthetic mitral valve thrombosis. Thrombolysis with a solution of recombinant tissue-type plasminogen activator resulted in the disappearance of electromechanical dissociation and was effective in stabilizing the patient's condition. The later discovery of panus covering the valve ring after the lysis of clots confirmed surgery as the definitive treatment.
