Right Heart Atrioventricular Thrombus in a SARS-CoV-2 Patient without Pulmonary Embolism: A Case Report

Abstract

SARS-CoV-2, the novel Coronavirus of 2019, and its associated coagulopathy has been reported to have many deleterious complications involving the cardiovascular system. Despite these many observed effects, there is a paucity of reports regarding SARS-CoV-2 and cardiac thrombus formation. In the absence of SARS-CoV-2, thrombi in the heart are typically seen in the left ventricle, with right heart thrombi (RHT) being very uncommon. When present, RHT are usually associated with pulmonary embolism (PE), which can lead to right sided heart failure in some cases. In rare instances, right heart thrombi are present in the absence of PE. In either situation, timely identification of RHT is critical as it carries a high mortality without timely treatment. Here, we present a unique case report detailing the presence of severe right heart failure from right atrioventricular thrombus without PE in a previously healthy patient diagnosed with SARS-CoV-2.
