A Case of Left Ventricular Thrombus and Herpetic Esophagitis in an Immunocompetent Patient With COVID-19.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been associated with thrombosis, both venous and arterial, but the mechanism behind this coagulation is not fully understood. Several cases involving coronavirus disease 2019 (COVID-19)-positive patients with left ventricular thrombus (LVT), particularly in those with low ejection fraction, have been reported. This report describes a case of a 57-year-old male patient who presented to the hospital with altered mental status and a positive SARS-CoV-2 polymerase chain reaction (PCR) test. CT of the chest revealed the presence of an LVT, and transthoracic echocardiography showed a reduced ejection fraction and confirmed the presence of the thrombus. The patient also reported epigastric chest pain and several bloody bowel movements. A colonoscopy revealed internal hemorrhoids. An esophagogastroduodenoscopy revealed the presence of multiple esophageal ulcers, and biopsy results confirmed herpes simplex virus (HSV) infection. The patient had no history of organ or bone marrow transplant, long-term immunosuppressive therapy, or HIV infection. He was eventually discharged on apixaban for his LVT and acyclovir for his HSV esophagitis.
