239. CCC: Approach to RV Predominant Cardiogenic Shock with Dr. Ryan Tedford

The CardioNerds podcast episode focuses on right ventricular (RV) shock, featuring Dr. Ryan Tedford as an expert guest. The hosts, along with CardioNerds Ambassador Dr. Pablo Sanchez, discuss the differences between RV and LV function, RV-PA coupling, and the etiologies of acute and chronic RV failure. They analyze three patient cases with RV dysfunction stemming from pulmonary embolism, RV infarction, and pulmonary arterial hypertension, respectively, interpreting hemodynamic data and discussing management strategies, including optimizing preload and afterload, inotropic support, and mechanical circulatory support options. The podcast emphasizes a comprehensive understanding of RV physiology and tailored approaches to managing RV failure in critically ill patients.
