B: Electrograms during pacing from CS 3-4 bipole, showing time to the mulitpolar catheter (PV) positioned in left atrial appendage is 156ms. C: Left anterior oblique fluoroscopic image of a patient with previous mitral annular ring. 2011-01-28 2012-03-07 Background: There are limited data on the use of a remote robotic catheter system (RCS) for mitral isthmus (MI) ablation. Methods: This single-center, prospective, matched control study included 45 patients who underwent atrial fibrillation ablation using a remote RCS compared to 45 patients who underwent conventional ablation. Subsequently, linear ablation of a left atrial roof and the mitral isthmus (MI) was performed.

Case report A 73-year-old man with paroxysmal atrial ﬁbrillation under-went catheter ablation. After the 4 PVs were completely iso-lated, the rhythm converted to persistent ﬂutter with a cycle length of 334 ms. A mitral isthmus (MI) linear lesion created in a reanimated human heart: (A) initiation of the linear lesion with support from a transseptal sheath and secondary diagnostic catheter; (B) the ablation catheter (1) is pulled along the MI with twisting of a diagnostic catheter (2) towards the fossa ovalis, and retraction of the transseptal sheath (3) from the left atrium; (C) increased deflection Mitral Isthmus Ablation Line Reconnections Are Common and Predicts Mitral Annular Dependent Flutters Following Pulmonary Vein Isolations for Atrial Fibrillation December 2011 Journal of Arrhythmia catheter (Map) along the superior mitral isthmus at the base of the LAA in a RAO 30°/caudal 15° projection. A multipolar electrode catheter was positioned in the coronary sinus (CS). In C, a circular mapping catheter was positioned inside the LAA to continuously monitor electric LAA activation during ablation of a mitral isthmus line.

2015-08-25 Epicardiac conduction via the vein of Marshall (VOM) can bypass the mitral isthmus (MI) line, making MI ablation difficult.

Mitral isthmus thickness predicted ablation failure with a ROC area of 0.84. The best threshold to predict MI ablation failure was 8.3 mm with a sensitivity of 67% and a specificity of 97%. Left atrial size was of greater importance in failed cases (2D echo surface: 24.1 ± 2.5 vs.

isthmus was part of the critical zone of the reentry circuit. A mitral isthmus line from the left inferior PV to the mitral isthmus was performed. During ablation, the atrial flutter terminated (Figure 5), and the ablation line was completed from the left inferior PV to the mitral valve annulus. After ablation, we demon- Linear mitral annular ablation was then delivered. Eventually, the ablation catheter was withdrawn to the right side and used to map the right atrium. RA activation appeared to be counterclockwise but was not entrained from the right side. Linear isthmus ablation was performed.

The use of steerable sheath and high ablation power may improve success rate. Methods: This single‐center Background: Mitral isthmus (MI) ablation for atrial tachyarrhythmias remains challenging.
