Coarctation of the aorta is a congenital anomaly representing 5-8% of all congenital cardiovascular malformations, which involves the narrowing (stenosis) of a segment of the aorta (the main vessel in the body). It can occur isolated (most frequently) or it can be associated with other cardiac malformations (ventricular septal defect, patent ductus arteriosus, valvular diseases – bicuspid aortic valve and, rarely, conditions that involve the right heart).
Classically, the coarctation is located at the level of the thoracic aorta distal to the origin of the left subclavian artery (the last branch of the initial segment of the aorta), but it can also involve the horizontal (transverse) segment of the aorta (the arch of the aorta). Rarely, the final segment of the thoracic aorta or the abdominal aorta can be involved, in these cases a longer segment of the vessel being involved.
The consequence is the obstruction of blood flow through the aorta. The narrowing is due to the ”infolding” of the internal layer of the aorta, which becomes a membrane with a central or lateral orrifice, making the flow through the vessel difficult.
Most frequently the diagnosis is made before the age of 10 years old, but sometimes (25% of cases) it is diagnosed later in life.
Mitral regurgitation (MR) is a condition in which the heart’s mitral valve leaflets do not close tightly. When this happens, blood flows backward from the heart’s left ventricle into the left atrium. The heart must then work harder to push blood through the body, which can cause fatigue, shortness of breath and worsening heart failure. It is the most common type of heart valve insufficiency.
