Background
- Causes
- Endocarditis
- Aortic dissection
- Always suspect in acute aortic regugitation
- Blunt chest trauma
Clinical Features
- Pulmonary edema
- Wide pulse pressure
- Dyspnea
- Hypotension (may progress to cardiogenic shock)
- Decrescendo diastolic murmur heard immediately after S2
Differential Diagnosis
Valvular Emergencies
Diagnosis
- CXR
- Pulmonary edema w/o cardiac enlargement
Treatment
- Immediate surgical intervention
- Reduce afterload
- Diuretics and nitrates don't work
- Don't use beta blockers (block compensatory tachycardia)
