Usually harmless in infants less than a year, the viral respiratory infection known as bronchiolitis can be life-threatening in youngsters with preexisting cardiac conditions. Our goal was to explain the connection between bronchiolitis and cardiovascular disease from every angle possible: Epidemiological, clinical, therapeutic, and evolutionary. Over the course of 5 years, from 2018 to 2023. There were 87 cases and 165 controls in all. One percent of all hospitalizations were due to bronchiolitis caused by cardiac defects. Isolated septal defect of the ventricular was the most common kind of cardiac disease seen during a bronchiolitis episode. About 54% of the cases were really serious. The presence of cardiopathy was linked to a number of factors, including the degree of seriousness of bronchiolitis with odds ratio 2.72, the use of oxygen therapy (odds ratio 24.28), the length of time spent in the hospital (odds ratio 7.1), the presence of a progressive course, and the severity of the cardiopathy itself (odds ratio 26.72). The death rate was 15.2 percent. Bronchiolitis is prevalent among kids who have congenital heart disease. Therefore, consider the likelihood of congenital heart disease when dealing with an episode of bronchiolitis, especially in the severe forms.
