Right Ventricle Thrombus in a Massive Pulmonary Embolism COVID-19 Patient

The coronavirus disease 2019 (COVID-19) infection presents with a wild range of clinical manifestations. Increased inflammatory response and thrombotic risk have been described, being pulmonary embolism a potential cause of death in these patients. Pulmonary embolisms with right ventricle thrombus are rare and have higher mortality rates. This case report concerns a rare clinical presentation of a 75-year-old male with a medical history of right renal transplantation 36 years ago, that presented with a ten-day history of asthenia, followed by fever, shortness of breath, and cough since the day before. He was admitted with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pneumonia and respiratory insufficiency. The next morning the patient worsened, he presented with hypotension, tachycardia, severe refractory hypoxemia, and chest pain. Contrast CT showed a massive pulmonary embolism with a right ventricle thrombus, confirmed by an echocardiogram. Anticoagulation and IV fluids were started, and the patient was transferred to the ICU. He developed obstructive shock, so thrombolysis was performed with a full dose of alteplase. The outcome was good with complete recovery. Posterior investigation excluded other causes for pulmonary embolism. The severity of pulmonary parenchymal disease secondary to COVID-19 correlates with thromboembolic complications, which demand a swift response to avoid death. An abrupt deterioration in oxygenation should raise suspicion for PE in COVID-19 patients, and mostly in the presence of hypotension and tachycardia. In our case report, there was a massive pulmonary embolism with a rare right ventricle thrombus that had a good outcome with medical treatment.
