A 5-year-old girl born to a mother with first-trimester rubella infection presents with cataracts, sensorineural deafness, and a continuous "machinery" murmur at the left infraclavicular region. Vital signs show HR 110/min, BP 125/70 mmHg with bounding pulses and wide pulse pressure, RR 22/min, and SpO2 98% on room air. She denies dyspnea. Chest X-ray reveals pulmonary congestion. Echocardiography confirms a hemodynamically significant left-to-right shunt. Which diagnosis is most likely?
- A)Pulmonary artery stenosis
- B)Ventricular septal defect with pulmonary hypertension
- C)Aortic stenosis with aortic insufficiency
- D)Atrial septal defect with anomalous pulmonary venous return
- E)Patent ductus arteriosus as part of congenital rubella syndromeGABARITO
