[Multiple percutaneous coronary stent implantation due to myocardial bridging--a case report]

Area of Science:

• Cardiology
• Interventional Cardiology

Background:

• Myocardial bridges are congenital anomalies where a segment of coronary artery tunneled within the myocardium.
• Acute coronary syndrome (ACS) can be a rare manifestation of myocardial bridging.

Observation:

• A case of a woman presenting with ACS due to myocardial bridging.
• Initial treatment involved percutaneous coronary intervention (PCI) with stent implantation.

Findings:

• The patient experienced recurrent ischemic events, including myocardial infarction due to subacute stent thrombosis and restenosis.
• Multiple re-interventions with additional stent implantations were performed.
• Despite interventions, the affected artery eventually occluded, with collateral circulation development.

Implications:

• This case underscores the complex and often challenging nature of managing myocardial bridges, particularly when presenting with ACS.
• Recurrent stent thrombosis and restenosis pose significant risks, necessitating careful consideration of PCI strategies.
• The case highlights the potential for late-stage arterial occlusion despite aggressive interventional management.
