Answer

A bedside echocardiogram in a patient with decompensated CHF is an important diagnostic tool in determining the etiology of pulmonary edema. Echocardiography can be used to evaluate LV systolic and diastolic function, as well as valvular function, and to assess for pericardial disease. New wall-motion abnormalities may suggest acute myocardial infarction. It is especially helpful in identifying a mechanical etiology for pulmonary edema, such as the following:

  • Acute papillary muscle rupture

  • Acute ventricular septal defect

  • Cardiac tamponade

  • Contained LV rupture

  • Valvular vegetation with resulting acute severe mitral, aortic regurgitation
