Lancisi's sign
Lancisi's sign is an emblematic clinical sign prominently discerned in patients with tricuspid regurgitation. It manifests as an unusually large venous wave, commonly referred to as a Giant V wave, that is conspicuous in the jugular vein. The underlying pathophysiological mechanism for this phenomenon is the retrograde flow of blood into the jugular vein. This backward flow results from an incompetent tricuspid valve that fails to prevent the backflow of blood during ventricular systole.[1]
Historical Background[edit | edit source]
The eponymous designation, "Lancisi's sign," pays homage to its identifier, the distinguished physician Giovanni Maria Lancisi.[2] Lancisi's contributions to medicine transcended this particular sign; he is remembered for numerous insights in cardiology and epidemiology. Through his observations, the correlation between the visible venous wave in the jugular vein and tricuspid regurgitation was elucidated, providing clinicians with a valuable non-invasive tool to suspect the presence of this condition.
Clinical Relevance[edit | edit source]
Lancisi's sign is not only significant for its historical context but also for its practical relevance in modern clinical medicine. The visible giant V wave in the jugular vein serves as a hallmark sign for clinicians to suspect tricuspid regurgitation. This can further prompt the physician to order more specific diagnostic tests, such as an echocardiogram, to confirm the diagnosis and assess the severity. Recognizing and acting on such clinical signs can significantly impact patient outcomes by ensuring early diagnosis and appropriate therapeutic interventions.
