A 48-year-old woman with mitral valve prolapse presents with sudden-onset severe dyspnea. Vital signs show BP 92/58, HR 118, RR 28, SpO2 88% on room air. Physical examination reveals a new holosystolic murmur radiating to the axilla. Echocardiography demonstrates acute left ventricular dilatation and a flail mitral leaflet. She denies recent chest trauma. She takes no cardiac medications. What acute valvular complication has most likely occurred?
- A)Rupture of the chordae tendineaeGABARITO
- B)Left atrial myxoma embolization
- C)Leaflet perforation from endocarditis
- D)Papillary muscle hypertrophy
- E)Acute aortic stenosis
Explicação
Rupture of the chordae tendineae in mitral valve prolapse causes acute mitral regurgitation, producing a new holosystolic murmur. The sudden onset of dyspnea, LV chamber enlargement, and acute decompensation are consistent with acute severe mitral regurgitatio... Ver explicação completa e trilha adaptativa →
