A hybrid approach to complex arrhythmias.

Area of Science:

• Cardiology
• Cardiac Surgery
• Electrophysiology

Background:

• Atrial fibrillation (AF) mechanisms remain incompletely understood, leading to suboptimal long-term outcomes with current rhythm control strategies like catheter ablation.
• Historically, AF treatment relied on invasive, anatomy-based surgical lesion sets, often requiring sternotomy and cardiac arrest, limiting widespread adoption.
• Advancements in energy sources (cryoablation, radiofrequency) and electrophysiology techniques have enabled less invasive approaches.

Purpose of the Study:

• To provide a historical overview of the evolution of minimally invasive surgical and hybrid procedures for atrial fibrillation treatment.
• To highlight the transition from complex open-heart surgery to less invasive, collaborative approaches.
• To discuss the development of new therapeutic possibilities through technological advancements.

Main Methods:

• Review of historical surgical techniques for atrial fibrillation.
• Analysis of the impact of evolving electrophysiology tools and energy sources.
• Examination of the development and integration of minimally invasive and hybrid procedures.

Main Results:

• Early surgical AF treatments were complex and invasive, with limited adoption.
• The introduction of controlled energy sources and improved electrophysiology catheters facilitated less invasive procedures.
• Hybrid approaches, combining endocardial and epicardial access with video-assisted technology, have expanded therapeutic options.

Conclusions:

• Minimally invasive surgical and hybrid procedures represent a significant evolution in atrial fibrillation management.
• Continued innovation aims for less aggressive and more comprehensive AF treatment strategies.
• Collaboration between electrophysiologists and cardiac surgeons is crucial for advancing AF therapies.
