RESUMEN
We present a case with cardiac metastasis of the great saphenous vein leiomyosarcoma (LMS) that presented to the emergency department with dyspnea and palpitations 2 months ago. In this patient, hemodynamic instability was caused by an extensive right ventricular cavity and outflow tract invasion of the LMS. Treatment of the patient included incomplete mass resection, adjuvant chemotherapy, and permanent pacemaker implantation (due to postoperative complete atrio-ventricular block).

We present a case with a large left ventricular (LV) thrombus that presented to the emergency department with dyspnea. Bedside transthoracic echocardiography demonstrated a huge hypermobile thrombus with a maximum of 8.6 × 2 cm in size extending to the aortic valve originating from the aneurysmatic apical wall of the LV. Treatment of the patient included complete thrombus resection with aneurysmectomy.

: The patients with intermediate-high risk pulmonary embolism who have acute right ventricular (RV) dysfunction and myocardial injury without overt hemodynamic compromise may be candidates for thrombolytic therapy. Alternative low-dose thrombolytic therapy strategies with prolonged infusion may further decrease the complication rates as its efficacy and safety have been previously proven in the management of prosthetic valve thrombosis. In this study, we aimed to investigate the clinical outcomes of low-dose prolonged thrombolytic therapy regimen in intermediate-high risk pulmonary embolism patients. This study enrolled 16 retrospectively evaluated patients (female 9, mean age: 70.9â±â13.5 years) with the diagnosis of acute pulmonary embolism who were treated with low-dose and slow-infusion of tissue-type plasminogen activator (t-PA). All patients underwent transthoracic echocardiography and computed tomography scan for assessment of thrombolytic therapy success. Low-dose prolonged thrombolytic therapy was successful in all patients. The mean t-PA dose used was 48.4â±â6.3âmg. There was residual segmental thrombus in nine (56.3%) patients after thrombolytic therapy. The arterial oxygen saturation and tricuspid annular plane systolic excursion increased after thrombolytic therapy whereas heart rate, RV to left ventricular (LV) ratio, systolic pulmonary artery pressure, and the frequencies of hypotension and tachypnea significantly decreased. There was no cerebrovascular accident or major bleeding requiring transfusion. There were two minor bleedings (12.5%) including hemoptysis and epistaxis. Thrombolytic therapy in these intermediate-high risk pulmonary embolism patients was associated with excellent clinical outcomes and survival to discharge (100%) without any 60-day mortality. Prolonged thrombolytic therapy regimen with low-dose and slow-infusion of t-PA may be associated with lower complication rates without comprimising effectiveness in patients with acute intermediate-high risk pulmonary embolism.
