Understanding heart conditions early can help support timely medical care. Coarctation of the aorta is a congenital condition in which part of the aorta becomes narrower than normal, making the heart work harder to circulate blood. Common signs may include high blood pressure, weak leg pulses, cold feet, chest discomfort, shortness of breath, headaches, or reduced exercise tolerance. Diagnosis may involve blood pressure checks, echocardiography, ECG, CT, MRI, or cardiac catheterisation.
