Which special maneuvers can augment the intensity of aortic insufficiency murmur?
Aortic insufficiency is best heard at the left lower sternal border with the patient leaning forward and in full expiration. The intensity of the murmur can increased by:
- Transient arterial occlusion:
By inflating blood pressure cuffs on both arms 40 mmHg above the systolic pressure for 20 seconds
Both of these maneuvers increase the afterload which increase the intensity of the murmur.
