De Musset's sign of venous origin - Lateral Head Bob (Heart rate ~130 bpm.) De Musset's of AR is to-and-fro. This is side-to-side. The pulsation in the neck is clearly venous, as the "inward" component is much more obvious than the outward component. It is monophasic: Lancisi's sign (CV fusion) of severe TR. There is a lateral head bob, which Marriott refers to as "de Musset's sign of venous origin" Severe TR based on: 1) Lancisi's monophasic CV wave, known as "arterialization of the venous pulse", often confused for carotid (but the obvious "inward" movement = venous); 2) lateral head bob, which Marriott refers to as "de Musset's sign of venous origin" Dr. André Mansoor @AndreMansoor - Author of Frameworks for Internal Medicine https://amzn.to/2LmUODZ #DeMussets #sign #venous #Lateral #HeadBob #TricuspidRegurgitation #TR #PhysicalExam #Clinical #Video
