Early diagnosis of congenital cardiovascular diseases (CCH) is of great importance in the morbidity and mortality of the newborn. Physical examination may not always help in diagnosis. A critical congenital heart disease screening with pulse oxymeter is beneficial in getting early diagnosis of asymptomatic babies. In this article, 3 cases of congenital heart disease diagnosed due to low oxygen saturation without respiratory problems after infection in the newborn intensive care unit for different reasons were mentioned. Two patients were diagnosed with ventricular septal defect pulmonary athesis, and one was diagnosed with trunkus arteriosis type 4. One of the incidents that began the E1 infusion of prostaglandin after the diagnosis with ecocardiography (EKO) was lost. The other two patients are undergoing surgery. Critical CT scan with low saturation detected in a baby with no clear cyanosis may have a duktus-dependent heart disease, and if no respiratory failure is observed when inserted, a pneumonia-dependent ventilation-perfusion disorder is not considered, first of all, CT should be understood. In second-level newborn intensive care units or when the child's cardiology doctor's opinion is not received, the patient's delivery to a center, which is the child's cardiology unit, by starting the E1 infusion of prostaglandin without expected to be shown with EKO, can be life-saving.
