A rare complication of percutaneous coronary intervention: Coronary pseudoaneurysm formation

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology

Background:

• Coronary pseudoaneurysms (CPAs) are uncommon but potentially life-threatening complications following percutaneous coronary interventions (PCI).
• CPAs can lead to severe outcomes such as stent thrombosis, distal embolization, and coronary rupture with cardiac tamponade.

Observation:

• A patient developed a CPA three weeks after undergoing PCI.
• The CPA presented a high-risk profile necessitating prompt management.

Findings:

• The patient was successfully treated with a percutaneous intervention.
• A covered stent was utilized as the primary therapeutic device for managing the CPA.

Implications:

• Percutaneous intervention with covered stents offers a viable and effective treatment option for high-risk coronary pseudoaneurysms.
• This approach may help prevent severe complications associated with untreated CPAs post-PCI.
