In international experience, performance improvement, patient safety, and quality assurance are mainly based on database studies in the field of pediatric and congenital cardiac surgery. Data collection and analysis of the databases allow the clinician to identify the complexity, to predict possible risks and complications, and to appropriately evaluate the outcomes and performances. Recently, the Children's Heart Foundation Working Group has developed a database project in Turkey based on the parameters and methodologies of the international databases, namely the Pediatric Heart Surgery National Database. Currently, it is a must for us to put this project into practice to reach the global standards in the pediatric and congenital heart surgery in our country. We believe that all children with congenital heart disease should have an opportunity to benefit from the most recent medical and surgical treatment modalities with the most favorable results.
