Creation of a systemic-to-pulmonary artery shunt by use of an internal mammary artery.
The creation of a systemic-to-pulmonary artery shunt by use of the internal mammary artery (IMA) in a 2-year-old boy with complex congenital heart defects and diminutive pulmonary arteries is described. This procedure may offer advantages over standard methods in selected patients with extremely small pulmonary arteries. The pliability, favorable anatomical position, and growth capability of the IMA reduce chances for complications, such as stenosing, kinking, and stretching of the pulmonary artery, which can cause it to become distorted, making further definitive repair difficult.
