Saddle Pulmonary Embolism and Thrombus-in-Transit Straddling the Patent
Foramen Ovale 28 Days After COVID Symptom Onset
Abstract
We present a late presentation of saddle pulmonary embolism and
thrombus-in-transit straddle the patent foramen on patient who
successfully recovered from severe acute respiratory syndrome
coronavirus-2 (COVID-19) pneumonia. Seven days post-discharge (i.e. 28
days after initial COVID-19 symptom onset), she was readmitted to
hospital for severe dyspnea. Computer tomography angiogram and
echocardiography confirmed the diagnosis. Severe pro-inflammatory and
pro-thrombotic states with endothelial involvement have been reported
associated with severe COVID-19 infection. However the duration of
hypercoagulable state has not yet known. This case highlights the risk
of thromboembolic phenomena for prolonged periods of times after
recovering from COVID-19 pneumonia.
