Large tricuspid valve thrombus complicating COVID-19 pneumonia

Abstract

Background: Hemostatic disturbances with coronavirus disease 2019 (COVID-19) can predispose to tricuspid and right heart thrombi in very rare instances. Aim: We describe a 29-year-old female patient without previous cause of thrombosis who developed large tricuspid valve thrombus (TVT) and moderate-to-severe tricuspid regurgitation (TR) during the course of COVID-19 infection. Materials and methods: Persistant fever and tachycardia with thrombocytopenia and high D-dimer increased the index of suspicion. The diagnosis was made by bedside transthoracic echocardiography (TTE) and cardiac magnetic resonance (CMR). Surgery was performed for thrombectomy and tricuspid valve replacement with a tissue valve. Discussion and conclusion: Detection of TVT in COVID-19 patients on the basis of high index of suspicion, bedside TTE and non-invasive CMR helps early surgical treatment and subsequent reduction of mortality and hospital stay.
