Abstract
Objective: To demonstrate the increased survival of patients with congenital heart disease in unfavorable conditions after adequate neonatal care and correct indication on pregnancy interruption. Details of the case: Infant, male, 7 months years old, patient in a pediatric outpatient Clinic in a city in the state of São Paulo. The patient was born with 30 weeks and 3 days of gestation, delivered by cesarean due to fetal tachycardia and decreased fetal movements. Weighting 1900 grams, measuring 41 centimeters and APGAR of 3/6. At birth, he was placed on mechanical ventilation, had neonatal depression, newborn’s respiratory distress syndrome, supraventricular tachycardia, fetal hydrops and neonatal hypoglycemia. An echocardiogram showed preserves systolic function of ventricles, congenitally corrected transposition of the basal vessels (CCTGA) and mild tricuspid insufficiency. An electrocardiogram revealed sinus rhythm, heart rate of 136 bpm, axis at zero degrees and short PR interval – showing a possible Wolff-Parkinson-White Syndrome (WPW) while the 24-hour Holter exam showed 43 episode of tachycardia paroxysmal junction, rare extrasystoles. Final considerations: The importance of adequate postnatal screening in relation to tachicardias and apneas provides the patient with early treatment, and consequently a better prognosis than if he had the diagnosis in adulthood, a period that diagnoses of CCTGA prevails.
