A 52-year-old man with chronic atrial fibrillation and rheumatic heart disease presents with dyspnea and new onset hemoptysis. Examination reveals an opening snap, loud S1, and diastolic murmur at the apex. Chest X-ray shows pulmonary edema with Kerley B lines. Which valve lesion is most likely the cause of his hemoptysis?
- A)Mitral regurgitation causing left atrial enlargement
- B)Aortic regurgitation causing pulmonary edema
- C)Tricuspid stenosis causing right heart failure
- D)Mitral stenosis causing pulmonary venous hypertensionGABARITO
- E)Pulmonary stenosis causing pulmonary hypertension
Explicação
Mitral stenosis causes obstruction to left atrial emptying, leading to pulmonary venous hypertension. This elevated pulmonary venous pressure causes pulmonary edema and alveolar hemorrhage, manifesting as hemoptysis. Kerley B lines on CXR indicate chronic pulm...
