This is a 74-year old gentleman with multiple medical comorbidities who was admitted to the ICU with septic shock and bacteremia. He's had a tumultuous course in the unit and has been difficult to wean from vasoactive agents. Below are two series of images. The first were taken earlier in his stay, while on higher doses of vasoactive agents and more acutely unwell. The second were taken a week later when he was clinically significantly improved and weaned from inotropic support; however, there was concerned that some of his Echo parameters had actually worsened! What are we looking at here, and what's the explanation?
