Implantation of cardiac rhythm devices during concomitant anticoagulation or antiplatelet therapy

Area of Science:

• Cardiology
• Electrophysiology
• Cardiovascular Medicine

Background:

• Cardiac rhythm device implantation is rising due to aging populations and increased heart failure and arrhythmia incidence.
• Concomitant use of oral anticoagulants and dual antiplatelet therapy is also increasing.
• Implanting cardiac devices in patients on these therapies heightens perioperative bleeding risks.

Purpose of the Study:

• To review current literature on managing patients on anticoagulation/antiplatelet therapy undergoing cardiac rhythm device implantation.
• To evaluate the efficacy and risks of traditional heparin bridging protocols.
• To propose alternative strategies for optimizing perioperative outcomes, minimizing bleeding and thrombotic risks.

Main Methods:

• Comprehensive literature review of studies on anticoagulation, antiplatelet therapy, and cardiac rhythm device implantation.
• Appraisal of existing data regarding perioperative bleeding and thrombotic complications.
• Synthesis of findings to develop evidence-based management strategies.

Main Results:

• Traditional heparin bridging may not be the optimal strategy for all patients.
• Limited literature exists, but suggests potential for increased bleeding complications with bridging.
• Alternative perioperative management strategies are needed.

Conclusions:

• Careful perioperative management is crucial for patients on anticoagulation/antiplatelet therapy undergoing cardiac device implantation.
• Strategies beyond traditional heparin bridging should be considered to balance bleeding and thrombotic risks.
• Further research is warranted to establish definitive guidelines.
