The word “tricuspid” is derived from the Latin, tri (three) and cuspis (cuspidis, a projection or point). Thus, the tricuspid valve is the anatomical structure in the heart with three valve leaflets (cusps) which separates the right atrium and ventricle. A variety of bedside signs have been discovered during the physical examination in patients with tricuspid insufficiency (TI) as a means to differentiate and diagnose this disease. These signs were elicited by examiners who applied one or more key fundamental physical examination skills including observation, palpation, auscultation, and passive maneuvers to identify or unmasked underlying TI. These signs have been eponymously named to honor those physicians’ contributions to medicine. With the exception of Pasteur (abdominojugular test) and Carvallo signs, the majority have not been well studied and thus their utility in clinical practice remains unknown. Despite the lack of consistent performance, technique, and case definition; the presence of a positive abdominojugular test increases the probability for diagnosing conditions that cause elevated right atrial or ventricular filling pressure and thus represents an accurate indirect method for determining whether the left atrial pressure is increased or pulmonary capillary wedge pressures ≥15 mmHg on cardiac catheterization. An understanding of the historical significance of these signs as originally described provides an appreciation for these findings and reinforces the importance of applying bedside techniques during the physical examination. Knowledge of these signs may also enhance one’s understanding of the pathophysiology of disease and provide opportunities for further investigation.
