Why the study?
Does robotic radiosurgical pulmonary vein isolation (RRPVI) cause late gadolinium enhancement on cardiac MRI in a patient with paroxysmal atrial fibrillation?
Does robotic radiosurgical pulmonary vein isolation (RRPVI) cause late gadolinium enhancement on cardiac MRI in a patient with paroxysmal atrial fibrillation?
This first-in-human case report demonstrates that robotic radiosurgical pulmonary vein isolation for paroxysmal atrial fibrillation results in left atrial enhancement detectable by LGE-CMR.
LA enhancement on LGE-CMR follows RRPVI; leaves open durability, safety, and clinical efficacy in paroxysmal AF.
Pulmonary vein isolation using robotic radiosurgery system CyberKnife is a new non-invasive treatment of atrial fibrillation, currently in clinical phase. Robotic radiosurgical pulmonary vein isolation (RRPVI) uses stereotactic, non-invasive (painless) pinpoint radiation energy delivery to a small, precise area to accomplish ablation. The purpose of this report is to describe the finding of an increase in the enhancement of the left atrium demonstrated with the use of cardiac magnetic resonance imaging using late gadolinium enhancement (LGE-CMR) as a result of RRPVI in the first case in the world in humans using CyberKnife as a treatment for paroxysmal atrial fibrillation (PAF).
