Septal Versus Lateral Mitral Isthmus Ablation for Treatment of Mitral Annular Flutter JACC Clin Electrophysiol . 2019 Nov;5(11):1292-1299. doi: 10.1016/j.jacep.2019.08.014.

The mitral isthmus is a critical part of perimitral reentrant tachycardia, as well as an important substrate of persistent atrial fibrillation. Deployment of an endocardial mitral isthmus line (MIL) with the end point of bidirectional block may be challenging and often requires additional epicardial ablation within the coronary sinus.

The mitral isthmus (MI) is the standard Oct 29, 2018 A novel mapping and ablation strategy of the mitral isthmus using intracardiac echocardiography in the left atrium. Thomas J. Flautt, DO. Nov 21, 2019 Mitral isthmus radiofrequency (RF) ablation is a well-established technique for the treatment of peri-mitral atrial flutter. It classically involves Oct 28, 2015 Mitral isthmus is often targeted as a part of stepwise approach during radiofrequency ablation for persistent atrial ablation. Acute success rate in of Ablation Line Predicts Bidirectional Mitral Isthmus Block in Patients Undergoing Catheter Ablation of Persistent Atrial. Fibrillation: A Randomized Controlled Jul 28, 2012 Mitral isthmus ablation forms part of the electrophysiologist's armoury in the catheter ablation treatment of atrial fibrillation. It is well recognised Jun 29, 2018 Cardiac tamponade developed in 2 patients due to mitral isthmus perforation, which did not interfere with completion of the ablation lesion set Aug 13, 2015 Mitral isthmus line 3. Mitral annular line 4.

Hypothesis: MI block could be achieved in most patients undergoing repeat LPeAF 2020-06-30 During ablation on the mitral isthmus, the atrial flutter prolonged (270 msec) and then terminated. 3. Discussion Cardiac surgeons were the pioneers of curative ablation of atrial fibrillation (AF). Since the 80’s, when Cox and colleagues introduced the LA isolation pro- An anterior ablation line, connecting the right upper pulmonary vein with anterior mitral annulus, including the scar area, was acomplished in 73% (n=11).

Epicardiac conduction via the vein of Marshall (VOM) can bypass the mitral isthmus (MI) line, making MI ablation difficult. This study aimed to assess the contribution of the VOM in achieving MI conduction block.

In C, a circular mapping catheter was positioned inside the LAA to continuously monitor electric LAA activation during ablation of a mitral isthmus line.

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. Subsequently, linear ablation of a left atrial roof and the mitral isthmus (MI) was performed. The MI ablation was applied from the 4 o’clock direction of the mitral annulus (MA) to the left-side Anousheh, R, et al.

The role of adjunctive MI ablation was controversial. Hypothesis: MI block could be achieved in most patients undergoing repeat LPeAF Mitral isthmus (MI) ablation was limited due to technical challenges in the index ablation for long‐standing persistent atrial fibrillation (LPeAF). The role of adjunctive MI ablation was controversial. Hypothesis. MI block could be achieved in most patients undergoing repeat LPeAF ablation and was associated with favorable clinical outcomes 2020-06-30 During ablation on the mitral isthmus, the atrial flutter prolonged (270 msec) and then terminated. 3.
