State-of-the-art Laser Ablation for Cardiac Arrhythmias: Development and Future Perspective-A State-of-the-art Review.

Cardiovascular laser application (CVLA) is an innovative approach in the field of cardiology aimed at treating various cardiovascular diseases, including cardiac arrhythmias, cardiomyopathies, systemic and pulmonary resistant hypertension, and varicose leg veins, by using a key technology, the laser. Tissue-selective photon absorption of the 1064-nm wavelength induces tissue-selective irreversible lesions of arrhythmogenic myocardium, modulation of retrocardiac ganglion plexi, and renal and pulmonary perivascular innervation. This review summarizes the development and the experimental and clinical results of the CVLA, highlighting its potential advantages over other catheter ablation methods. Based on its unique characteristics, laser treatment has the potential to become an all-pervasive, safe, and effective procedure for the benefit of countless patients.
