Retrograde percutaneous coronary intervention for acute myocardial infarction following blunt chest trauma

Area of Science:

• Cardiology
• Interventional Cardiology
• Trauma Surgery

Background:

• Blunt chest trauma can precipitate acute myocardial infarction (AMI).
• Standard antegrade percutaneous coronary intervention (PCI) may be challenging in trauma-induced coronary artery occlusion.
• Timely reperfusion therapy is critical for managing AMI.

Observation:

• A 78-year-old male presented with chest pain and ST-elevation AMI post-blunt chest trauma.
• Coronary angiography revealed an occluded right coronary artery with a large false lumen due to trauma.
• Antegrade PCI was unsuccessful, but retrograde guidewire manipulation successfully navigated the lesion.

Findings:

• Successful retrograde PCI was performed by crossing the occluded lesion via a retrograde approach.
• Two drug-eluting stents were deployed to restore blood flow.
• This represents the first reported case of successful retrograde PCI for trauma-induced AMI.

Implications:

• Retrograde PCI is a viable strategy for complex coronary occlusions resulting from blunt chest trauma.
• This technique offers a potential solution for reperfusion therapy when antegrade approaches fail.
• Further research may explore the broader application of retrograde techniques in traumatic cardiac events.
