Appearing and disappearing right-heart thrombus: a case reporto in COVID-19 patient
European Heart Journal, Supplement(2021)
Abstract
Abstract Aims Venous thromboembolism represents frequent complication of patients with severe COVID-19 disease. Several reports about atypical thrombosis are described, rarely it has been described a right venticular thrombus during the course of infection. We report a case of right endoventricular thrombosis in a patient with SARS-Cov-2 pneumonia. Methods and results A 58-year-old man was admitted to our ward for severe respiratory failure in interstitial pneumonia. The nasopharyngeal swab for COVID-19 resulted positive. Steroids and prophylaxis with LMWH were started, associated to CPAP to maintain good gas exchange. During hospitalization a venous ECD was performed with evidence of left popliteal thrombosis despite the therapy. d-Dimer was 4463 ng/ml. A new onset AF was documented at the telemetry, without troponin elevation. A cardiac ultrasound was performed showing a right endoventricular lesion of 1.8 cm adhering to the free wall of the right ventricle. A CT-pulmonary angiogram (CTPA) resulted negative for pulmonary embolism and confirmed suspected right ventricular thrombus. Treatment with fondaparinux 7.5 mg was started. After 10 days, cardiac ultrasound shown complete resolution of thrombosis, and CT confirmed the disappearing of the mass. Dabigatran 150 mg twice/day was started. Patient clinically improved and he was discharged after 20 days of hospitalization. Conclusions SARS-CoV-2 infection may cause inflammation with cytokine storm and hypercoagulability leading to venous thromboembolism. Atypical thrombus formation was reported, including right-ventricle free wall. Early caridac ultrasound was critical to make diagnosis and starting prompt treatment, therefore routine cardiac ultrasound is mandatory in severe COVID-19 patients.
