Guimarães & Guimarães Profile of a pediatric cardiac ICU Int J Cardiovasc Sci. 2020; 33(4):331-336 Original Article Themost common diagnoses of acyanotic heart defects were IVC (24.5%), followed by total AVSD (19.9%), PAC and IAC (13.2% each), coarctation of the aorta (11.9%), partial AVSD (7.3%), pulmonary valve stenosis (PVS) (4.6%), aortic stenosis (4%), and double outlet right ventricle (DORV) + subaortic IVC (1.3%). Among the cyanotic congenital heart defects, the most common was tetralogy of Fallot (30%), followed by tricuspid atresia (17.6%), complex heart diseases (15.3%), pulmonary atresia (9.9%), TGA (9.2%), DORV + PS (6.1%), TAPVR (6.1%), single ventricle and truncus arteriosus (2.3% each) and Enstein anomaly (0.8%). Among children and adolescents with complications of surgical repair (n = 94), 64.3% had hemodynamic complications, 33.3% had infection, 27.2% coagulation disturbances, 14% arrythmias, 6.5% renal complications, 6.5% procedural complications, and 3,2% neurological complications. ECC was used in 138 patients; duration of ECC was < 90 minutes in 52.2%, 90-120 minutes in 21%, and > 120 minutes in 26.8%. Mean time of ECCwas 95.2 ± 53.7 minutes, varying from 12 to 261 minutes. Mean length of stay at the ICU was 9.7 ± 16.4 days, varying from one to 181 days. ICU length of stay was < 7 days for 73.3% of patients, 8-15 days for 15.3% and > 15 days for 11.4%.
