Area of Science:

  • Cardiology
  • Cardiac Surgery

Background:

  • Coronary artery disease (CAD) poses risks to patients, including potential complications like ischaemic mitral regurgitation (IMR).
  • Chronic ischaemic papillary muscle dysfunction is a recognized severe complication of ischaemic heart disease.

Observation:

  • A patient presented with dyspnoea but notably lacked angina of effort.
  • Cardiovascular investigations, including right heart catheterisation, were performed.

Findings:

  • Severe mitral regurgitation was identified.
  • This severe mitral regurgitation was observed exclusively during angioplasty of the left marginal artery.

Implications:

  • This case underscores the importance of considering IMR in patients with CAD, even without typical angina.

  • The findings suggest that haemodynamic stress during interventions like angioplasty can unmask or exacerbate IMR.
  • Further research into the mechanisms and management of IMR triggered by interventions is warranted.
