Anticoagulation and antiplatelet therapy in implantation of electrophysiological devices

Area of Science:

• Cardiology
• Electrophysiology
• Vascular Medicine

Background:

• Increasing use of implantable electrophysiological devices coincides with rising rates of antithrombotic therapy in cardiovascular disease patients.
• Effective periprocedural strategies are vital to prevent bleeding complications during device implantation.
• Managing anticoagulation and antiplatelet therapy perioperatively is complex.

Purpose of the Study:

• To review current data on anticoagulation and antiplatelet therapy in arrhythmia device surgery.
• To discuss risk factors and procedural parameters associated with hemorrhagic events.
• To identify optimal prophylactic strategies for bleeding prevention.

Main Methods:

• Review of existing literature on antithrombotic therapy and device surgery.
• Critical analysis of risk factors for hemorrhagic complications.
• Evaluation of current evidence regarding specific antithrombotic regimens.

Main Results:

• Heparin bridging in patients on chronic anticoagulation and dual-antiplatelet therapy increases pocket hematoma risk.
• Continuing oral anticoagulation and short-term clopidogrel interruption with aspirin maintenance show promise and acceptable safety.
• Supportive measures and experienced operators in high-volume centers can further reduce hematoma incidence.

Conclusions:

• Perioperative management of antithrombotic therapy requires careful consideration of individual patient risk.
• Continuation of oral anticoagulation and selective clopidogrel interruption are viable strategies.
• Further randomized studies are needed to refine antithrombotic protocols and update clinical guidelines.
