Insights

Balloon angioplasty successfully treated a critical atherosclerotic lesion within left anterior descending myocardial bridging in an elderly patient. This case highlights a rare but effective treatment for refractory angina pectoris.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Vascular Biology

Background:

  • Atherosclerotic lesions in myocardial bridging can cause refractory angina pectoris.
  • Myocardial bridging is a congenital anomaly where a segment of coronary artery lies embedded within the myocardium.
  • Complex atherosclerotic lesions at the distal extent of myocardial bridging pose unique therapeutic challenges.

Observation:

  • An 86-year-old patient with prior angina and stroke presented with acute myocardial infarction and concurrent nonhemorrhagic stroke.
  • Medical therapy for post-myocardial infarction angina was ineffective.
  • Coronary angiography revealed a complex, critical atherosclerotic lesion at the distal end of a long left anterior descending (LAD) myocardial bridge.

Findings:

  • The "culprit" lesion was successfully treated with balloon angioplasty.
  • This represents the second reported case of successful balloon angioplasty for atherosclerotic lesions within LAD myocardial bridging.
  • The patient's refractory angina was resolved following the intervention.

Implications:

  • Balloon angioplasty is a viable revascularization strategy for complex atherosclerotic lesions in myocardial bridging.
  • This approach may offer an alternative to surgical intervention in select patients.
  • Further research is warranted to understand the long-term efficacy and safety of this treatment modality.
