Persistent stenosis or recoarctation occurs in 16 to 33% of infants who undergo repair of coarctation of the thoracic aorta by use of end-to-end anastomosis. This report describes the results in 12 infants of repair of coarctation of the aorta using a left subclavian artery flap procedure. Cardiac catheterization and cineangiography performed in four patients from 4 to 66 months following repair showed a 10 mm systolic gradient in one patient and no evidence of significant stenosis in any patient. The eight other patients have had recent sphygmomanometer pressures recorded from 1 to 29 months after repair. Four patients had no gradient while three patients had a systolic pressure gradient of 8, 10, and 12 mm Hg. Results suggest a smaller incidence of persistent stenosis or recoarctation following subclavian flap procedure than following end-to-end anastomosis. The subclavian flap operation provides an adequate aortic lumen with good growth potential. It is recommended as the operation of choice for infants with the most common form of coarctation of the aorta.

D001017	Aortic Coarctation	A birth defect characterized by the narrowing of the AORTA that can be of varying degree and at any point from the transverse arch to the iliac bifurcation. Aortic coarctation causes arterial HYPERTENSION before the point of narrowing and arterial HYPOTENSION beyond the narrowed portion.

D013348	Subclavian Artery	Artery arising from the brachiocephalic trunk on the right side and from the arch of the aorta on the left side. It distributes to the neck, thoracic wall, spinal cord, brain, meninges, and upper limb.	Arteries, Subclavian,Artery, Subclavian,Subclavian Arteries
D013524	Surgical Flaps	Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature which is also transferred to the new site. They are often used in plastic surgery for filling a defect in a neighboring region.
