[Management of high thrombus burden in primary PCI]

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• Large thrombus burden is a frequent finding in primary percutaneous coronary intervention.
• This condition is associated with an increased risk of procedural complications.

Purpose of the Study:

• To discuss the management of large thrombus burdens during primary percutaneous coronary intervention.
• To evaluate the roles of intracoronary thrombolysis, glycoprotein IIb/IIIa inhibitors, and thromboaspiration.
• To review dedicated thrombus management stents and stenting strategies.

Main Methods:

• Discussion of current therapeutic options and their limitations.
• Review of techniques for thromboaspiration and use of dedicated stents.
• Consideration of direct versus delayed stenting approaches.

Main Results:

• Thromboaspiration requires specific techniques, and filter capacities can be exceeded.
• Stents designed for thrombus management have specific benefits and drawbacks.
• Direct stenting is generally encouraged, but delayed stenting may be considered for severe thrombotic cases.

Conclusions:

• Optimal management of large thrombus burden involves a combination of pharmacotherapy and mechanical approaches.
• Careful technique is essential for effective thromboaspiration.
• Delayed stenting warrants consideration in select cases with significant thrombotic burden.
