Analysis of 14,843 Neonatal Congenital Heart Surgical Procedures in the European Association for Cardiothoracic Surgery Congenital Database

In neonatal congenital heart surgery significant risk of early death extends beyond 30 postoperative days. Multivariate analysis confirmed that lower body weight, higher ABS, longer CPB time, longer aortic cross-clamp time, longer circulatory arrest time, and univentricular physiology are risk factors for hospital mortality. Higher ABS as well as longer CPB time and circulatory arrest time are associated with the rate of complications.
