Acute pulmonary embolism with floating right intra-ventricular thrombus is a rare phenomena associated with poor prognosis. Here, we are presenting a case of 35-year-young male with no co-morbid illness diagnosed to have right ventricular thrombus with bilateral pulmonary embolism, which was managed successfully with thrombolytic therapy.

Right Ventricular thrombus presenting with acute pulmonary embolism is a rare phenomena associated with poor prognosis. Here we are presenting one such case who was managed successfully with thrmbolytic therapy.
| Case report|| |
A 35-year-old young soldier with no co-morbid illness was air-evacuated from 18,400 feet to our hospital (located at 11,500 feet) with a history of right upper abdominal pain. He had a tachycardia of 112/min, respiratory rate of 35/min, blood pressure of 110/70 mm Hg and oxygen saturation of 88% on room air. Hematological and biochemical parameters were normal. Ultrasound of the abdomen was otherwise normal except mild ascites. 12-lead electrocardiogram revealed tachycardia with T-wave inversion in lead V1-V4. Chest radiograph revealed a significant cardiomegaly. Bedside trans-thoracic echocardiography showed a moderately dilated right ventricle with impaired right ventricular systolic function containing a large free echogenic mass consistent with a thrombus with normal pulmonary artery pressure [Figure 1]. Urgent computed tomography pulmonary angiography revealed massive bilateral pulmonary embolism [Figure 2] and [Figure 3]. Patient was started on oxygen inhalation, low-molecular-weight heparin and oral anticoagulation.
On next day, patient developed hypotension (blood pressure of 80 mm Hg systolic). Immediately, he was given intravenous tissue plasminogen activator. Postthrombolytic therapy, his blood pressure improved and oxygen requirement also decreased. Repeat trans-thoracic echocardiography performed after 12 h showed no evidence of the right ventricular thrombus [Figure 4]. Subsequently, he was maintained on intravenous heparin and switched over to long-term oral anticoagulation. Follow-up trans-thoracic echocardiography showed improved right ventricular function. Patient was transferred to a tertiary center at near sea-level and was followed-up for 2 months. Subsequent recovery was uneventful, and the patient was discharged on anticoagulation after 2 months.

| Discussion|| |
In high altitude scenario, a rare case of biventricular thrombus has been reported to be associated with protein S deficiency.  Right heart thrombus when present with pulmonary thromboembolism is associated with greater mortality. In a study where 2454 cases of pulmonary embolism were studied and 1113 cases were described, 42 cases of right heart thrombus had twice the mortality rate at 14 days and 3 months of 21% and 29% respectively compared to mortality rate of 11% and 16% respectively in cases of pulmonary embolism.  The findings of hemodynamic compromise like in our case such as hypotension (systolic blood pressure [SBP] <90 mm Hg) in cases of right heart thrombus were observed in 14% of cases compared to 4% of cases of pulmonary embolism without right heart thrombus. 
The mortality in the cases of right heart thrombus treated with heparin alone, thrombolysis and surgical embolectomy was 23.5%, 20.8% and 25% respectively.  In another retrospective study, which analyzed 177 cases of right heart embolism, mortality rate in cases with no therapy, anticoagulation therapy, surgical embolectomy and thrombolysis was 100%, 28.6%, 23.8% and 11.3% respectively.  Further analysis revealed association of improved survival rate associated with thrombolysis therapy compared to other treatment options.  The difference in the treatment-associated mortality in cases of right heart thrombus is attributed to subject selection, presence of co-morbidities determining treatment selection and varying number of cases treated in the three treatment option groups.
The most common complication associated with thrombolysis was bleeding that occurred in 21.9% of the cases compared to a rate of 7.9% in cases treated with heparin alone.  A review of described recent studies showing occurrence of bleeding between 20% and 25% of treated cases and 5-10% major bleeding.  The commonest site for a major bleed was intracranial with a mortality of 50%. 
Acute pulmonary embolism with floating right intra-ventricular thrombus is a rare phenomena associated with poor prognosis. , American college of chest physicians  suggest that the thrombolytic therapy should be administered in the patient with acute pulmonary embolism associated with hypotension (SBP <90 mm Hg) (as in our case). This case illustrates uncommon clinical presentation of uncommon right ventricular thrombus with bilateral pulmonary embolism and underlies the importance of serial echocardiography as a key examination in patients with a suspected embolism.
