Homografts and Xenografts for Right Ventricular Outflow Tract Reconstruction: Long-Term Results

Non-blood group-compatible homografts have a significantly higher early reoperation rate than blood group-compatible homografts. Contegra grafts have a very low early reoperation rate and could therefore be used in neonates and children younger than 3 years of age, if a blood group-compatible homograft cannot be found. In children older than 3 years blood group compatibility is less important.
