The surgical difficulty of congenital heart disease varies greatly. To ensure the safety of surgery and maximize the benefits of patients, various congenital heart surgery scoring systems have been used to evaluate the risk of different complex congenital cardiac operations. However, the complete correction of cardiac anatomical malformations is a common surgical challenge. Recent studies have shown that the correction is closely related to perioperative mortality and postoperative complications, and a new scoring system for the degree of cardiac anatomical malformations has been proposed. Therefore, this review summarizes the literature and discusses different evaluative methods of congenital heart surgery, aiming to optimize the surgical evaluation system for congenital heart surgery, enhance the quality of surgery and improve the prognosis of patients.
