A 33 year old woman develops sudden right arm weakness after a long flight. Venous duplex ultrasound shows a calf deep venous thrombosis. Brain imaging confirms a small ischemic infarct. Echocardiography with bubble study shows transient right to left flow across the atrial septum during a Valsalva maneuver. Which of the following is the most likely diagnosis?
- A)Tricuspid atresia
- B)Patent foramen ovaleGABARITO
- C)Secundum atrial septal defect
- D)Endocardial cushion defect
- E)Persistent truncus arteriosus
Explicação
A patent foramen ovale is usually asymptomatic but can permit paradoxical embolization when transient right atrial pressure exceeds left atrial pressure, such as during Valsalva. The combination of DVT, stroke, and bubble study evidence of transient right to l... Ver explicação completa e trilha adaptativa →
