The Convergent procedure for AF: A surgeon's perspective

Area of Science:

• Cardiology
• Cardiac Surgery
• Medical Devices

Background:

• Persistent and long-standing persistent atrial fibrillation present treatment challenges.
• Current treatment strategies may not be sufficient for complex cases.
• A hybrid approach combining epicardial and endocardial ablations is being explored.

Purpose of the Study:

• To evaluate the effectiveness of the Convergent IDE Trial in improving patient outcomes.
• To identify and address the unique surgical challenges associated with the epicardial stage of the Convergent procedure.
• To assess the potential of the Convergent procedure as an off-pump surgical armamentarium for atrial fibrillation.

Main Methods:

• A heart team hybrid approach involving staged epicardial and endocardial ablations.
• Utilizing the Convergent procedure for the epicardial stage.
• Addressing challenges in left atrial anatomy, visualization, and appendage management.

Main Results:

• The Converge IDE Trial demonstrated improved patient outcomes in a challenging persistent atrial fibrillation population.
• The study identified specific surgical challenges including unfamiliarity with left atrial posterior anatomy and minimally invasive left atrial appendage management.
• Successful management of these challenges is crucial for procedure adoption.

Conclusions:

• The Convergent procedure, when combined with endocardial ablation, offers improved outcomes for persistent atrial fibrillation.
• Overcoming surgical challenges is essential for the widespread adoption of this off-pump approach.
• The Convergent procedure should be considered a valuable addition to the surgical treatment of atrial fibrillation.
