This patient's systolic murmur was heard over the entire precordium but was loudest in the third interspace near the sternum. The patient was asked to do the Valsalva maneuver and the murmur definitely increased in loudness. This would favor a diagnosis of:

• A

  Mitral regurgitation

   

• B

  Hypertrophic obstructive cardiomyopathy

   

• C

  An innocent murmur
