Insights

Iatrogenic coronary artery dissection, though uncommon, can occur during catheter procedures. This case highlights a rare right coronary cusp dissection causing heart rhythm issues, managed successfully with stenting.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Vascular Medicine

Background:

  • Iatrogenic coronary artery dissection is a known complication during cardiac catheterization.
  • Right coronary cusp dissection is a rare but serious iatrogenic injury.

Observation:

  • A 54-year-old woman developed exertional dyspnea and chest discomfort post-diagnostic angiography.
  • Delayed sub-intimal hematoma formation led to compression of the right coronary artery ostium and SA node branch.

Findings:

  • The compression resulted in sinoatrial (SA) node dysfunction, causing junctional rhythm and atrial fibrillation.
  • Successful management was achieved through stenting of the coronary ostium entry point.

Implications:

  • This case underscores the importance of recognizing and managing rare iatrogenic coronary ostial dissections.
  • Stenting the entry point offers a logical and effective solution for catastrophic dissections involving aortic cusps.
