LEFT-VENTRICULAR THROMBUS IN A 2-YEAR-OLD BOY WITH CARDIOMYOPATHY - LYSIS WITH RECOMBINANT TISSUE-TYPE PLASMINOGEN-ACTIVATOR

A 2-year-old boy with cardiomyopathy and clinical signs of cardiac failure presented with an echodense structure in the left ventricle. This structure was seen from different echocardiographic views adjacent to a hypokinetic area of the apex and lateral free wall. It was different in texture and motion from the underlying myocardium and thus met the diagnostic criteria of a left ventricular thrombus. This thrombus protruded into the cavum and was partly mobile. In view of a high embolic risk, thrombolytic therapy with recombinant tissue plasminogen activator was started. The thrombus resolved within 72 h without any embolic or bleeding complications. No recurrence of the thrombus was observed during a 3-month follow up period.
