Coarctation of the aorta preoperative management typically includes which of the following?

• A. Balloon angioplasty
• B. Prostaglandin infusion preoperatively
• C. Beta-blocker therapy
• D. ACE inhibitor therapy

Answer: (B)

Maintaining blood flow to the lower body in neonates with ductal-dependent coarctation is the key idea. In this situation, the narrowing of the aorta is so severe that the body’s circulation relies on the ductus arteriosus to shuttle blood past the obstruction. Giving prostaglandin E1 (alprostadil) keeps the ductus open, preserving patency of the conduit between the pulmonary and systemic circulations. This stabilizes perfusion to the lower body and vital organs while preparing for definitive repair, preventing rapid deterioration from poor distal blood flow. Balloon angioplasty can relieve the obstruction, but it isn’t the standard preoperative stabilization for all patients and isn’t as universally used as a bridging therapy. Beta-blocker or ACE inhibitor therapies don’t address the essential need to keep the ductus open in ductal-dependent cases, and they don’t reliably improve distal perfusion preoperatively.
