Unmasking Culprit Complex Infero-Posterior STEMI: Navigating Ad Hoc RCA CTO PCI

Area of Science:

• Interventional Cardiology
• Cardiovascular Medicine
• Acute Coronary Syndromes

Background:

• ST-segment elevation myocardial infarction (STEMI) necessitates prompt reperfusion to preserve myocardial tissue.
• Coronary artery bypass grafting (CABG) is a common treatment for coronary artery disease, but grafts can occlude.
• Occluded grafts with significant thrombus present complex challenges for revascularization.

Observation:

• A patient presented with STEMI attributed to a thrombosed, occluded coronary artery bypass graft.
• The occluded graft contained an extensive thrombus burden, complicating direct intervention.
• A strategic decision was made to pursue revascularization of the native coronary artery instead of the graft.

Findings:

• Successful revascularization of the chronically occluded native vessel was achieved.
• This approach circumvented the challenges posed by the occluded graft and thrombus.
• The case demonstrates an alternative strategy in complex STEMI management.

Implications:

• This case highlights the importance of considering native vessel revascularization in STEMI patients with occluded grafts.
• Advanced interventional techniques and strategic decision-making are crucial for managing complex thrombotic coronary lesions.
• Such cases expand the understanding of treatment options for myocardial infarction in the context of prior revascularization.
