  • The only ones that are systolic murmurs are Aortic Stenosis, Mitral Regurg, Tricuspid Regurg
  • Aortic Stenosis often radiates to the carotid, not the axilla
  • Tricuspid Regurgitation is usually heard at the tricuspid area and doesn't radiate
  • Mitral Regurgitation is loudest at apex and radiates towards axilla. Therefore, this is the right answer.
