Successful thrombolysis of mechanical mitral valve prosthesis in a patient with cardiogenic shock.

A 48-year-old woman with cardiogenic shock was admitted to a nearby hospital. Her medical history included mechanical replacement of her mitral valve 4 years previously in Russia because of rheumatic stenosis. On admission, her international normalised ratio (INR) was significantly reduced below the therapeutic limit. A severe stenosis of the valve prosthesis was identified by transthoracic and transoesophageal echocardiography and the patient was transferred to our university hospital for discussion of an immediate therapeutic procedure and to ensure cardiac surgical backup. Here, the patient's poor clinical status led to the decision for a non-routine treatment: a successful series of intravenous thrombolysis with alteplase. Clinical symptoms and echocardiographic parameters improved significantly.
