Balloon coarctoplasty, also known as balloon angioplasty for coarctation of the aorta, is a minimally invasive procedure used to treat a narrowing (coarctation) in the aorta, the main artery that carries blood from the heart to the rest of the body. The procedure involves inserting a catheter with a balloon at its tip through a blood vessel, typically in the groin, and guiding it to the narrowed segment of the aorta. Once positioned, the balloon is inflated to stretch the narrowed area and improve blood flow. After deflation, the catheter is removed. This procedure can provide immediate relief from symptoms such as high blood pressure and heart strain, but there is a risk of restenosis (re-narrowing) or other complications such as aortic dissection. Follow-up monitoring is essential to assess long-term outcomes and determine if further treatment is needed.
