Etude PROTECT : Prognostic Role of Tapse Evaluation in Children's bronchioliTis

"Non interventional study (study of a prognostic factor). The study procedure is the echocardiographic assessment of TAPSE at every admission in PICU for acute bronchiolitis.~Transthoracic echocardiography is a non invasive, non radiative examination, that is usually performed at every admission in PICU, however not mandatory. Inclusion in the study will lead to a systematic echocardiographic assessment at admission, potentially adding this examination to the patient's course.~As transthoracic echocardiography is systematically monitored in intubated children, no additional examination will be necessary for those requiring invasive mechanical ventilation."
