Abstract

Objective: To describe the epidemiological and paraclinical characteristics of patients with severe congenital heart failure with increased blood flow to the lungs. Subjects and research methods: Cross-sectional descriptive study, convenience sampling. All patients with server heart failure (class IV) due to congenital heart disease with increased blood flow according to Ross classification are treated at Cardiovascular resuscitation unit - Department of Cardiology - Cardiovascular Center - of the National Children's Hospital from August 2021 to July 2022. Results: Forty two patients with mean age of 5.49 ±4,6 months old from 2 months old to 6 years old, average weight 8,32 ± 5,67.kg. The most common disease was ventricular septal defect (33.2%). The average length of stay in hospitals of the successful group is 7.26 ± 5.67 days and the failure group are 14.2 ± 2.8 days (p > 0.05). Other disease when patients hopitalizing  were pneumonia (33%), acute diarrhea accounted for 21.4%, urinary infection 16.7%. all patients were treated with drugs; surgical diseases accounted for 35.7%. There are 7.14 % of patients receiving intervention. The symptoms of dyspnea, tachycardia and hepatomegaly and the manifestations of enlarged heart on chest X-ray, ventricular thickening, and decreased EF all improved after treatment (p<0.01). Conclusion: Ventricular septal defect is the most common congenital heart in the group of congenital heart with increased blood flow to the lungs, accompanying diseases in respiratory failure are mainly pneumonia, acute diarrhea. The clinical and subclinical symptoms of the studied patients mostly improved after treatment
