Article Synopsis
- Dark-blood late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) is more effective than bright-blood LGE CMR for accurately defining ablation scars in the left atrium of patients undergoing atrial fibrillation ablation.
- This study examined the optimal signal intensity threshold of dark-blood LGE CMR to identify these scars, utilizing image intensity ratios (IIRs) from 54 patients.
- The results suggest an optimal IIR threshold of 1.09, with recommendations to use a range of 1.00 to 1.10 due to interpatient variability in detecting LA ablation scars.
Background: Surgical epicardial atrial fibrillation (AF) ablation can be performed as a stand-alone (thoracoscopic) procedure or concomitant to other cardiac surgery. In hybrid AF ablation thoracoscopic surgical epicardial ablation is combined with a percutaneous endocardial ablation. The Medtronic Gemini-S clamp is a surgical tool that uses irrigated bipolar biparietal radiofrequency (RF) energy applied with two clamp lesions that overlap to create one epicardial box lesion including the posterior left atrial wall and the pulmonary veins.
