Authors' objectives:
Atrial fibrillation (AF) is the most common type of cardiac arrhythmia, affecting an estimated 2.7 to 6.1 million individuals in the United States and 6 million individuals in Europe.
Description of
Technology: Minimally invasive cardiac ablation techniques for the treatment of AF involve creating linear, continuous, and transmural lesions in the atria as a means to produce scarring that disrupts erratic electrical conduction and helps regulate the heartbeat. Laser balloon ablation (LBA) utilizes laser energy to create lesions in the heart tissue. In LBA, a thin, flexible catheter is advanced through a vein, typically in the groin (femoral vein), up into the heart. Using fluoroscopy, the catheter balloon is positioned and inflated at the ostium of the pulmonary veins (PV). Upon tissue contact, a micro-endoscope is used to visualize the placement of each arc of infrared laser light on the cardiac tissue. Overlapping arcs of continuous laser light energy locally heat the atrial tissue around the PV, initiating cell death and formation of scar tissue. Several 20- to 30-second applications of energy are applied to obtain complete isolation. For AF, LBA may be an effective alternative treatment to cryoballoon ablation or radiofrequency ablation; however, there is uncertainty regarding the comparative effectiveness and safety between the cardiac ablation modalities.
Patient Population: LBA systems, such as the HeartLight Endoscopic Ablation System (CardioFocus Inc.), are indicated for use in patients with drug-refractory recurrent symptomatic paroxysmal atrial fibrillation.
Clinical Alternatives: Alternatives to LBA include other minimally invasive ablation techniques using radiofrequency, cryoballoon, microwave, or high-frequency ultrasound energy, as well as more invasive surgical ablation interventions such as the Cox-Maze procedure.
