Summary

A large left ventricular aneurysm can develop even with normal coronary angiograms, highlighting the need for thorough cardiac evaluation. This case underscores that normal coronary arteries do not rule out significant left ventricular wall abnormalities.

Area of Science:

  • Cardiology
  • Cardiovascular Surgery

Background:

  • Left ventricular true aneurysm involves systolic dyskinesia and fibrous tissue replacement of myocardial structure.
  • Occlusion of the left anterior descending coronary artery is the most common cause of left ventricular aneurysm formation.

Observation:

  • A 51-year-old male with a history of myocardial infarction presented with cardiac arrest and subsequent heart failure symptoms.
  • Coronary angiography revealed normal coronary arteries, but ventriculography showed a large, dyskinetic left ventricular aneurysm with mural thrombus.
  • Intraoperative findings confirmed an 8 cm aneurysm containing a fresh thrombus.

Findings:

  • Histopathology confirmed scar tissue consistent with a healed myocardial infarction.
  • Despite normal coronary arteries, a large true left ventricular aneurysm was surgically resected.

Implications:

  • Normal coronary angiograms do not exclude the development of large true left ventricular aneurysms.
  • This case emphasizes the importance of considering ventricular anatomy and function even in the absence of obstructive coronary artery disease.
