Background & aim Congenital heart malformation (CHM) is one of the most frequent and important abnormalities in newborns. In this study we retrospectively analyzed the frequency and distribution of the congenital heart diseases in our NICU.
Method Newborns hospitalized in NICU between 2005 and 2011 were retrospectively analyzed. Gestational age, birth weight, consanguinity, type of congenital heart disease extracted from the computerized database. CHMswere classified as follows; left-to-right shunt, obstructive, cyanotic with decreased pulmonary flow, cyanotic with increased pulmonary flow and others.
Results A total of 706 newborns were diagnosed as congenital heart disease during 7-year study period among the 7450 admission (9.5%). Consanguinity rate was 22.3% and 30.4% of these were first degree relatives. 42.7%, 17.3%, 13%, 11.6% were left-to-right shunt, obstructive, cyanotic with decreased pulmonary flow, cyanotic with increased pulmonary flow and others, respectively. Most frequent heart malformations were ASD (25.5%), VSD (12.6%), Aortic coarctation (10.8%), PDA (9.5%), TGA (8.8%), pulmonary atresia (8.2%), AVSD (4.1%), hypoplastic left heart (3.8%), pulmonary stenosis (3.1%), TOF (2.5%). 37 % of the newborns had at least one congenital malformation in other organ systems.
Conclusion ASD, VSD and aortic coarctation were most common congenital heart disease followed in our NICU.
