Insights

A rare case of intermittent left anterior descending artery obstruction caused by a calcified pericardial ring due to constrictive pericarditis is presented. This highlights a unique cause of coronary artery compression.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Internal Medicine

Background:

  • Constrictive pericarditis is a condition characterized by inflammation and thickening of the pericardium, potentially leading to impaired cardiac filling.
  • Coronary artery compression is an uncommon complication of constrictive pericarditis, with few documented cases.

Observation:

  • A 62-year-old male presented with intermittent obstruction of the left anterior descending artery.
  • The obstruction was found to be caused by a heavily calcified pericardial ring.

Findings:

  • The case demonstrates a unique etiology of coronary artery compromise, specifically compression by a calcified pericardial ring associated with constrictive pericarditis.
  • This presentation is rare, emphasizing the diverse pathological mechanisms that can affect coronary blood flow.

Implications:

  • This case underscores the importance of considering extrinsic cardiac compression in the differential diagnosis of coronary artery obstruction, even in the absence of typical atherosclerotic risk factors.
  • Further investigation into the relationship between pericardial disease and coronary artery compromise may be warranted.
