Coronary Artery-Ventricular Pseudoaneurysm Fistula After Myocardial Infarction

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiovascular Surgery

Background:

• Acute myocardial infarction (MI) is a leading cause of cardiovascular mortality.
• Left circumflex artery (LCx) occlusion can lead to significant myocardial damage.
• Complications following MI, such as fistulas and pseudoaneurysms, are uncommon but serious.

Purpose of the Study:

• To report a rare case of a left circumflex artery fistula and pseudoaneurysm developing after acute myocardial infarction.
• To highlight the importance of recognizing and managing these potentially life-threatening complications.
• To discuss the diagnostic and therapeutic challenges associated with post-MI fistulas and pseudoaneurysms.

Main Methods:

• Case report of a 56-year-old male patient.
• Diagnosis of acute myocardial infarction due to left circumflex artery occlusion.
• Follow-up imaging after conservative treatment revealed the development of a fistula and pseudoaneurysm.

Main Results:

• The patient presented with chest pain, diagnosed with acute myocardial infarction.
• Conservative management was initiated for the myocardial infarction.
• Subsequent imaging demonstrated an unexpected fistula between the left circumflex artery and the left ventricle, and a pseudoaneurysm.

Conclusions:

• Fistula and pseudoaneurysm formation can occur as delayed complications after acute myocardial infarction, even with conservative management.
• Vigilant monitoring and advanced imaging are crucial for detecting these rare sequelae.
• Management strategies for such complications require careful consideration of patient stability and anatomical features.
