What is the primary reason for identifying coarctation of the aorta in patients with a bicuspid aortic valve?

Identifying coarctation of the aorta in patients with a bicuspid aortic valve is primarily important for preventing hypertension. Bicuspid aortic valve is a commonly associated congenital condition with an increased risk of developing aortic coarctation. This coarctation can result in significant systemic hypertension due to the obstruction of blood flow in the aorta, particularly affecting the arteries distal to the coarctation. If left undetected, it may lead to long-term cardiovascular complications, including heart failure, aortic rupture, and other sequelae related to chronic hypertension. Therefore, early identification and management of coarctation are crucial to minimizing these risks and preventing adverse outcomes related to elevated blood pressure.

While evaluation for stenosis, assessment of cardiac output, and monitoring ventricular function are also important in managing patients with congenital heart defects, these factors are not primarily focused on the consequences and renal and hemodynamic implications directly related to coarctation and resultant hypertension.
