Thrombus aspiration for treating distal coronary macroemboli during primary percutaneous coronary intervention

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• Percutaneous coronary interventions (PCI) on thrombus-containing lesions carry risks like distal embolization and reduced coronary flow.
• Thrombectomy devices for thrombus aspiration during primary PCI are not standard but show increasing evidence of benefit.

Observation:

• A 70-year-old patient developed coronary bifurcation macroemboli during primary PCI.
• These emboli complicated the initial phase of the intervention, impacting coronary circulation.

Findings:

• Successful thrombus aspiration therapy was performed to address the macroemboli.
• Following the aspiration, significant improvements in coronary blood flow were observed.
• Dramatic resolution of ST-segment elevation was achieved post-intervention.

Implications:

• Thrombus aspiration can be a valuable tool for managing embolic complications during PCI.
• This case supports the growing evidence for using thrombus aspiration catheters in specific PCI scenarios.
• Effective management of embolic events can lead to better procedural outcomes and myocardial reperfusion.
