Some of the procedures for congenital heart disease can be performed through a lateral incision. The lateral incisions include anterolateral, posterolateral, direct axillary, and mini-axillary, of which the mini-axillary is the most difficult, more demanding, less tolerant of errors, and slightly more risky, but has the best cosmetic results. There is some uncertainty about the lateral incision, for example, some say that it can lead to scoliosis. I have recently reviewed a large body of literature and this statement is incorrect. The literature shows that left posterior posterolateral incisions, such as aortic constriction and the conventional route of arterial catheterization (non-axillary incisions), result in some degree of scoliosis in 20-30% of patients in the long term, but other incisions, such as axillary incisions and anterolateral incisions, have no evidence of scoliosis and, in theory, do not occur. For arterial catheterization, I have recently started experimenting with a tiny mid-axillary incision in the last two years, which is only 2 cm, with minimal damage and very good results. Therefore, parents are advised to make a lateral incision for the future development of their child.
