Coarctation of the aorta is characterized by a narrowing or constriction of the aorta, typically located just distal to the left subclavian artery, which leads to an obstruction of blood flow through the vessel. This condition can have significant impacts on blood circulation, causing differential hypertension between the upper and lower parts of the body. The increased pressure in the upper body can lead to complications, while the lower body may experience reduced blood flow. Recognizing this obstruction is crucial, as it often requires prompt medical intervention to correct the narrowing and restore normal blood circulation.

While the other options present misconceptions about coarctation of the aorta, the essence of the condition lies in this obstruction to blood flow, making it a critical factor for treatment and management in clinical practice. Understanding this feature is vital for recognizing the implications of the condition in both immediate and long-term care scenarios for those affected.
