Summary

A patient experienced ST elevation during angiography due to right coronary artery occlusion affecting the conus branch. This case highlights a rare cause of anterior precordial ST elevation.

Area of Science:

  • Cardiology
  • Medical Imaging

Background:

  • Coronary angiography is a key diagnostic tool for evaluating coronary artery disease.
  • ST elevation on electrocardiography (ECG) typically indicates acute myocardial infarction.

Observation:

  • A 70-year-old male patient presented with anterior precordial ST elevation during coronary angiography.
  • The left coronary artery was found to be normal.
  • Injection into a proximally occluded right coronary artery led to occlusion of its conus branch.

Findings:

  • The observed ST elevation was linked to the occlusion of the conus branch of the right coronary artery.
  • Electrocardiographic changes were correlated with the specific coronary artery anomaly.
  • The case report details the pathogenesis of this specific ECG manifestation.

Implications:

  • This case expands the understanding of ST elevation causes beyond typical myocardial infarction.
  • It underscores the importance of considering non-atherosclerotic causes or specific branch occlusions in coronary angiography.
  • Further research may elucidate the precise mechanisms and clinical significance of conus branch occlusion-induced ST elevation.
