A 3-month-old male presents with poor feeding and a harsh holosystolic murmur best heard at the left lower sternal border. Vital signs show HR 145 bpm, RR 42/min, BP 92/58 mmHg, and SpO2 98% on room air. He gains weight appropriately and has no cyanosis. Chest radiograph reveals mild cardiomegaly with normal pulmonary vascularity. Echocardiography demonstrates a defect in the ventricular septum with left-to-right shunting. Which congenital lesion is most likely?
- A)Tetralogy of Fallot
- B)Atrial septal defect
- C)Patent ductus arteriosus
- D)Coarctation of the aorta
- E)Ventricular septal defectGABARITO
Explicação
Ventricular septal defect is correct. A left to right shunt across the interventricular septum produces a harsh holosystolic murmur at the left lower sternal border. Small defects may be asymptomatic except for the murmur. Ver explicação completa e trilha adaptativa →
