Mitral regurgitation


Which of the following is not true of Mitral Regurgitation?

  • The S1 can be soft
  • The murmur is Pansystolic
  • There is no A wave in the JVP
  • The murmur may be due to functional dilation of the LV (e.g. in cardiomyopathy)
  • It is a common cause of atrial fibrillation

There is no A wave in the JVP.

In MR the atrial contraction will still cause an A wave, unless the patient is in AF. Remember also: displaced apex beat (from the 5th intercostal space mid clavicular line towards anterior axilliary line/6th/7th intercostal space).
