Coronavirus Disease 2019 (COVID 19) , is characterized by extreme virulence and a complex spectrum of pathologies ranging in severity from mild to multi-organ failure 3 and death. Over the past nine months, our knowledge of the pathophysiology and extrapulmonary manifestations of COVID-19 has grown tremendously. Yet, despite this, we are constantly discovering new manifestations such as the development of a hypercoagulable state 4-6 . With an anxious global community focused upon the development of a novel vaccine, it's easy to overlook that unique and potentially fatal complications are yet to be identified. In the current issue of "Journal of Thoracic and Cardiovascular Surgery TECHNIQUES," Manghat 7 and his team provide a single case-report describing a newly discovered, potential life- This case also highlights that the hypercoagulability associated with the COVID-19 infection may extend far beyond VTE and extend into arterial or implantable prostheses thromboses. Our surgical community is rapidly realizing that the extrapulmonary manifestations of COVID-19 infection have yet to be fully elucidated, especially in the post cardiac surgery patients. Anticoagulation therapy falls into standard guidelines, with heparin followed by coumadin for thrombosed prosthetic valve. A new question now arises: should we treat all COVID positive cardiac surgical patient with coumadin? While such a sweeping strategy might seem overreaching, this reader suggests this treatment prudent if we focus upon prosthetic valve patients, where a tendency towards such complications has already been historically established. The Manghat team case-report is another in a series of revelations highlighting the rapid evolution of our knowledge of COVID-19, and reminding us that we still have a great deal more to learn about this landmark disease. While no anticoagulation therapy post tissue valve implantation works in a majority of cases, it may not be appropriate in COVID-19 patients.
