Diagnosis

You are incorrect - the most likely diagnosis in our patient is acute mitral regurgitation from rupture of the chordae tendineae.

Your choice: Acute mitral regurgitation from ruptured papillary muscle

In patients with a ruptured papillary muscle, acute mitral regurgitation can occur and is usually due to acute myocardial infarction or chest trauma. The severity of the mitral regurgitation depends upon the extent of the rupture. The frequent result is severe mitral regurgitation that invariably presents with acute pulmonary edema.
