Recurrent Chronic Thromboembolic Disease Despite Optimal Anticoagulation In Setting Of Recent Covid-19 Infection

We present a case of a 38-year-old man with a history of chronic thromboembolic pulmonary hypertension on therapeutic anticoagulation and recent hospitalisation for COVID-19 disease who was hospitalised for recurrent acute pulmonary embolism despite therapeutic anticoagulation with warfarin (International Normalized Ratio (INR) of 3.0). Our case highlights the hypercoagulable state associated with COVID-19 disease and the absence of standardised approaches to anticoagulation treatment for this population.
