Coopernail Sign
Coopernail Sign (pronunciation: /ˈkuːpərneɪl saɪn/) is a medical term used to describe a specific clinical finding in patients with certain cardiovascular conditions.
Etymology
The term "Coopernail Sign" is named after Dr. John Coopernail, a renowned cardiologist who first described this sign in his patients.
Definition
The Coopernail Sign refers to a specific physical examination finding where there is a visible pulsation of the nail bed in patients with aortic insufficiency. This sign is indicative of a significant volume of blood regurgitating back into the left ventricle during diastole.
Related Terms
- Aortic Insufficiency: A condition where the aortic valve does not close tightly, causing the blood to flow backward into the heart.
- Diastole: The phase of the heartbeat when the heart muscle relaxes and allows the chambers to fill with blood.
- Pulsation: A rhythmic throbbing or vibrating, especially as in an artery following each beat of the heart.
Clinical Significance
The presence of the Coopernail Sign can help clinicians identify patients with severe aortic insufficiency. It is one of several physical examination findings that can suggest this diagnosis, along with other signs such as a widened pulse pressure and a diastolic murmur.
