Mr. Enlow claims: Abraham Lincoln was probably about six years older than his faked birth date of Feb. 12, 1809, and no more resembled Thomas Lincoln than his true half-brother, Wesley Enloe, who shares the same ultra-lanky frame inherited from their father (see a photo comparison).
Heart valve disorders can arise from two main types of malfunctions: Regurgitation (or leakage of the valve). The valve(s) does not close completely, causing the blood to flow backward through the valve. The heart is forced to pump more blood on the next beat, making it work harder. Stenosis (or narrowing of the valve). The valve(s) opening becomes narrowed, limiting the flow of blood out of the ventricles or atria.
They then close, keeping blood from flowing backward. The tricuspid valve separates the right lower heart chamber (the right ventricle) from the right upper heart chamber (right atrium). Tricuspid regurgitation is a disorder in which this valve does not close tight enough. This problem causes blood to flow backward into the right upper heart chamber (atrium) when the right lower heart chamber (ventricle) contracts. An increase in size of the right ventricle is the most common cause of this condition.
