A 3-month-old infant with hypotonia, upslanting palpebral fissures, and a single transverse palmar crease presents with poor feeding and tachypnea. Vital signs show HR 155/min, RR 48/min, BP 65/42 mmHg, and SpO2 92% on room air. Chest X-ray demonstrates cardiomegaly with pulmonary edema. Echocardiography reveals a common atrioventricular valve with primum and secundum atrial septal defects plus a ventricular septal defect. No cyanosis is currently present. Which diagnosis best explains these findings?
- A)Coarctation of the aorta
- B)Transposition of the great arteries
- C)Patent ductus arteriosus
- D)Endocardial cushion defectGABARITO
- E)Tetralogy of Fallot
Explicação
An endocardial cushion defect produces an atrioventricular septal defect and is strongly associated with trisomy 21. The infant's dysmorphic features and the presence of a common AV valve with septal defects are classic. These lesions create significant left t... Ver explicação completa e trilha adaptativa →
