Mitral Regurgitation

Cardiology

Systolic backflow from LV to LA.

Causes

  • • Primary (degenerative, endocarditis, rheumatic)
  • • Secondary (functional/ischaemic, LV dilatation)

Clinical features

  • • Dyspnoea, fatigue, palpitations (AF), acute pulm oedema if rupture

Examination

  • • Pansystolic murmur at apex radiating to axilla
  • • Displaced apex
  • • S3

Investigations

  • • Echo (severity, mechanism, LV size, EF)
  • • TOE for surgical planning
  • • BNP

Management

  • • Primary severe symptomatic → MV repair (preferred) or replacement
  • • Secondary → optimise HF Rx first; consider transcatheter edge-to-edge repair (COAPT criteria)
  • • Acute severe MR → emergency surgery + IABP bridge

Complications

  • • HF, AF, pulmonary HTN, endocarditis
