| |
| **Once symptoms present mean surival is 2-3yr
| |
| *Late systolic murmur radiating to carotids
| |
| *Pulsus parvus et tardus

| *Narrowed pulse pressure
| |
| ===Treatment===
| |

| |
| *Avoid BBs, CCBs
| |
| *Afterload reduction is controversial
| |
| **Consider cards consult
| |

| |
| *Causes
| |
| **Endocarditis
| |
| **Aortic dissection
| |
| **Blunt chest trauma
| |
| ===Diagnosis===
| |
| *Pulmonary edema
| |
| *Wide pulse pressure
| |

| |
| *Immediate surgical intervention
| |
| *Reduce afterload
| |
| **Nitroprusside
| |
| *Diuretics and nitrates don't work
| |
