In medical terms, cardiac artery coarctation is a phenomenon in which the aorta of the heart becomes coarcted and ruptures. This is when the blood in the aortic lumen of the heart tears from the inner lining of the aorta, and the blood enters the middle membrane of the aorta, causing it to separate, so that the highly pressurized blood expands along the long axis of the aorta, resulting in the separation of the true and false chambers of the aortic wall. A ruptured cardiac artery is a very rare disease, but once it strikes, it can have very serious consequences. When a person has a ruptured artery, there is typically severe pain, usually slashing or tearing-like pain. We must pay attention to this disease, and if it occurs, must be sent to the hospital at the first opportunity.
