Two cases of complications of the thrombolysis of right heart free-floating thrombi with pulmonary embolism: important role of echocardiographically based management.
We present two cases where successful thrombolysis of right heart thrombi and pulmonary embolism was accompanied by serious adverse events. In patient 1 with massive pulmonary thromboembolism, transesophageal ultrasound revealed large right atrial thrombus entrapped in a patent foramen ovale. Initial treatment with heparin was substituted with thrombolysis, which resulted in clinical improvement and dissolution of right heart thrombus but was followed by fatal intracerebral haemorrhage. In patient 2, thrombolysis caused mobilisation of thrombotic mass as evidenced by disappearance of thrombus on ultrasound. Massive pulmonary thromboembolism resulted in circulatory collapse. Short cardiopulmonary resuscitation restored spontaneous circulation and the patient recovered completely.
