AORTIC SPINDLE OF HIS Meaning and Definition

1. The term "aortic spindle of His" refers to a specialized structure located in the aorta, which is the main artery distributing oxygenated blood from the heart to the rest of the body. The aortic spindle of His is a thickening or bulging of the inner layer of the aortic wall known as the intima in a specific region called the sinus of Valsalva. It is named after the German physician Wilhelm His, Jr., who first described it.

   The aortic spindle of His serves an essential role in the regulation of blood flow by containing the aortic semilunar valves, which prevent the backflow of blood into the left ventricle during diastole (the relaxation phase of the cardiac cycle). These valves consist of three cup-shaped cusps or leaflets that are anchored to the aortic spindle of His.

   The aortic spindle of His also plays a crucial role in preventing the dilation of the aorta and thereby maintaining the structural integrity and functionality of the arterial system. It helps to ensure optimal blood flow to the body's organs and tissues by regulating the pressure, direction, and timing of the blood pumped by the heart.

   In summary, the aortic spindle of His is a specialized bulging in the aortic wall containing the aortic semilunar valves. It is involved in preventing the backflow of blood and maintaining the proper functioning of the arterial system by regulating blood flow.

2. A fusiform dilatation of the aorta following congenital narrowing at the part corresponding to the ductus arteriosus.
