An atypical case of iatrogenic LAD dissection following PCI: Diagnostic and management challenges

Area of Science:

• Cardiology
• Interventional Cardiology
• Radiology

Background:

• Iatrogenic coronary artery dissection is a rare but serious complication of routine interventional cardiology procedures like percutaneous coronary intervention (PCI).
• These dissections, though infrequent, can result in significant myocardial injury and mortality.
• Understanding the nuances of these events is crucial for patient outcomes.

Observation:

• A case of iatrogenic left anterior descending (LAD) artery dissection is presented.
• The dissection occurred at an atypical site.
• Notably, the patient exhibited ischemic damage without apparent symptoms.

Findings:

• The iatrogenic LAD dissection led to the development of ischemic dilated cardiomyopathy.
• Radiological and clinical features of this dissection were unusual.
• Despite significant ischemic damage, the patient remained asymptomatic.

Implications:

• This case underscores the importance of recognizing rare complications in interventional cardiology.
• The atypical presentation and asymptomatic ischemic damage highlight the need for vigilant monitoring.
• Effective management necessitates a multidisciplinary team approach for complex coronary artery dissections.
