Thirty-day mortality was 1.36%, hospital mortality 1.7% and 5-year survival probability 97%. The risk factors for early and late mortality were NYHA class III and IV symptoms (p < 0.0001; OR 30.8), history of heart failure (p = 0.001; OR 6.7), cyanosis (p < 0.0001; OR 60.5), number of previous operations (p = 0.00033), presence of mechanical prosthetic valves (p = 0.0032; OR 3.7) and univentricular circulation (p = 0.0276; OR 5.4). The difference was not significant for arrhythmias (p = 0.078), pulmonary hypertension (p = 0.072), age at operation (p = 0.372) and gender (p = 0.48).
Centralization of adult CHD care in a high volume center carries very good surgical results with low early and late mortality. It is important to perform the operations in time and to eliminate all residual lesions by combined surgical procedure. The presence of pediatric cardiac surgeon is necessary for the operations of complex CHD.
