A full-term newborn develops cyanosis (SpO2 78%), tachypnea (RR 68), and hepatomegaly within hours of birth. Heart rate is 165 bpm; blood pressure is normal. The mother took lithium for bipolar disorder during the first trimester. Chest X-ray shows cardiomegaly with pulmonary edema. Echocardiography reveals apical displacement of tricuspid valve leaflets with severe tricuspid regurgitation. There is no evidence of sepsis. Which of the following is the most likely diagnosis?
- A)Transposition of the great arteries
- B)Endocardial cushion defect
- C)Patent ductus arteriosus
- D)Tetralogy of Fallot
- E)Ebstein anomalyGABARITO
Explicação
Ebstein anomaly is correct. Prenatal lithium exposure is associated with apical displacement of the tricuspid valve, creating a large right atrium and severe tricuspid regurgitation. Newborns can present with cyanosis and right sided heart failure due to ineff... Ver explicação completa e trilha adaptativa →
