Successful Primary Percutaneous Coronary Intervention without Stenting: Insight from Optimal Coherence Tomography

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Imaging

Background:

• Current guidelines for acute myocardial infarction (AMI) recommend drug-eluting stents (DES) and prolonged dual antiplatelet therapy (DAPT).
• Emerging evidence suggests that in select AMI cases involving plaque erosion (not rupture), antithrombotic therapy alone may be effective.
• Optical coherence tomography (OCT) is crucial for differentiating plaque morphology.

Observation:

• A pilot study indicated favorable outcomes with antithrombotic therapy alone in select AMI cases without stent implantation.
• This approach was successful when optical coherence tomography (OCT) confirmed plaque erosion, not definite plaque rupture.

Findings:

• This case report details a successful primary percutaneous coronary intervention (PCI) without stent implantation.
• Optical coherence tomography (OCT) guided the decision-making process, identifying plaque erosion in a patient with ST-elevation myocardial infarction (STEMI).
• The intervention addressed thrombotic total occlusion of the right coronary artery.

Implications:

• OCT imaging may enable non-stenting strategies in specific acute myocardial infarction presentations.
• This approach could potentially reduce the need for lifelong DAPT and associated bleeding risks.
• Further research is warranted to validate the safety and efficacy of non-stenting strategies in STEMI patients with plaque erosion.
