Abstract Background Great variability exists in repair strategies for the tetralogy of Fallot. While transannular patching, as introduced by Kirklin, was a breakthrough for primary repair, pulmonary regurgitation and a need for reoperation have led to the development of methods that preserve the natural morphology of the right ventricular outflow tract. Methods State‐of‐the‐art details of tetralogy of Fallot repair are explained from the standpoint of architectural preservation, especially with regard to sparing native tissue such as the annulus, valve, or infundibulum. Particular attention is given to the latest technical details of each approach, benefits and disadvantages, and any long‐term data available. Results The choice of procedure is complex and unique to each case as transannular patching alone may carry long‐term pulmonary risks. Modifications that spare the annulus, valves, or infundibulum may thus be essential as preservation of natural morphology has resulted in excellent mid‐term results. Conclusions The complexity of tetralogy of Fallot repair demands constant attention to clinical presentation and vigilance against long‐term sequelae. Techniques will continue to improve over time as long‐term data guides the refinement of these innovative surgical methods.
