Introduction: COVID-19 infection significantly increases the risk for thromboembolic complications which can cause multi organ dysfunctions and worsen patients clinical course and prognosis. (1-3)

Case report: We are presenting a 73-years-old patient admitted to ICU unit due to first episode of sudden dyspnea, syncope and chest pain. He has no history of previous cardiovascular or respiratory disease, no history of thromboembolism (PTE) or deep vein thrombosis (DVT). ECG showed atrial fibrillation with HR 120 bpm and incomplete RBBB. Blood pressure was 85/45mmHg with cold periphery. Patient denied any provocable PE risk factors. Bed site POCUS (Point-of-Care Ultrasound) echocardiography was performed immediately in order to evaluate the cause of patient symptoms and hemodynamic instability. Examination showed increased right ventricle (RV) size, reduced RV function (TAPSE 13, TDI S’ 9), presence of McConnell’s sign, severe tricuspid regurgitation with dilated v. cava and signs of pulmonary hypertension. Due to hemodynamic instability and indirect signs of the presence pf pulmonary embolism fibrinolysis with alteplase infusion was applied. Patient hemodynamically stabilized after first hour. Nasopharyngeal smear for SARV CoV-2 was taken due to ongoing pandemic and result come out positive for virus RNK (real-time fluorescence polymerase chain reaction-PCR). CT angiography was performed which showed large intraluminal thrombi in the right pulmonary artery, extending to left pulmonary artery up to subsegmental level. His D-dimer values were 7813 ng/ml, CRP 123 mg/L. Evaluated sPESI score was 2, which indicated elevated 30-day death risk. Patient remained clinically stable. He was transferred to the infectious disease clinic for further treatment. After two weeks was discharged with recommendations for three months anticoagulation treatment with Rivaroxaban. Patient performed control visit at our clinic after four months. He was stable, asymptomatic with normal right ventricular function.

Conclusion: This is case of successful treatment of pulmonary embolism complicated with cardiogenic shock as a first manifestation of COVID-19 infection at our clinic since the start of pandemic. POCUS echocardiography is fast noninvasive method that help us urgently assess the cause of patient instability and guide diagnostic approach and patient management.
