In January, The Society of Thoracic Surgeons, the Society of Cardiovascular Anesthesiologists, and the American Society of ExtraCorporeal Technology released a clinical practice guideline on the use of blood thinning medication (anticoagulants) during heart surgery. In this episode, guideline coauthor John Hammon, MD speaks with two cardiothoracic surgeons (Gaetano Paone, MD and Richard Engelman, MD) and a perfusionist (Theron Paugh, CCP) about how the guideline will change clinical practice.
