Coarctation Of Aorta In Children

Coarctation of aorta (CoA) is a discrete narrowing in aorta causing obstruction to the flow of blood. It accounts for 6-8% of all congenital heart diseases. With advances in fetal echocardiography rate of prenatal diagnosis of coarctation of aorta has improved but it still remains a challenging diagnosis to make prenatally. Transthoracic echocardiography is mainstay of making initial diagnosis and routine follow-up. Cardiac magnetic resonance imaging (MRI) and computed tomography (CT) are great advanced imaging tools for two-dimensional and three-dimensional imaging of aortic arch in complex cases. Based on type of coarctation, size of patient, severity of lesion, and associated abnormalities various management options like surgical treatment, transcatheter balloon angioplasty and transcatheter stent implantation are available. There is significant improvement in long-term survival from pre-surgical era to post-surgical era. But, among the postsurgical era patients, the long-term survival has not significantly changed between older and contemporary cohort. Patients with coarctation of aorta need lifelong follow-up event after successful initial intervention.
