Ablation Of Persistent Atrial Fibrillation Substrate In Sinus Rhythm Does Not Lead To An Underestimation Of Fibrotic Atrial Myopathy: A Pilot Study, David Goldgrab Do, Sokol Kalaveshi Md, Jose Luis Henao Md, Ruifang Yang Md, Jearim Craig, Stephen Mester Md, Christian Perzanowski Md

Cardiology

Introduction | Objectives: Ablation of persistent atrial fibrillation (peAF) is associated with a worse outcome. Fibrotic atrial myopathy (FAM) is thought to play a role in the progression of AF. Estimation of left atrial voltage can vary significantly based on whether mapping is performed in fibrillatory conduction or sinus rhythm (SR). Selection of a voltage scale (VS) may lead to an over/under estimation of FAM. We determined the prevalence of advanced atrial myopathy (FAM > = 2) in SR compared to historical cohort ablated in peAF.

Methods: A homogenous group of peAF patients who underwent ablation in SR following cardioversion were …

Is The Thomas Ring An Effective Approach To Prevent Recurrence Of Persistent Atrial Fibrillation With Advanced Atrial Fibrosis?, Ruifang Yang Md, Jose Luis Henao Md, David Goldgrab Do, Sokol Kalaveshi Md, Stephen Mester Md, Christian Perzanowski Md

Cardiology

Introduction | Objectives: Pulmonary vein isolation (PVI) with the Thomas ring (TR, single ring posterior wall isolation) has been shown to reduce recurrence of primarily paroxysmal atrial fibrillation (AF). Atrial fibrosis, as an important pathophysiological contributor, is directly linked to AF recurrence and resistance to therapy. The effect of TR ablation on outcomes of persistent AF (peAF) with advanced atrial fibrosis has not been adequately studied.

Methods: Observational series of three peAF patients (Tab.) who underwent TR. The degree of atrial fibrosis was determined by electroanatomic bipolar voltage mapping (CARTO, Diamond Bar, CA, USA). The reduced voltage areas (Fig.) reflected …

A Crescent Lesion Set Avoiding Esophageal Contact Is Not Inferior To Standard Waca For Paroxysmal Afib: A Pilot Study, Jeraim Craig, David Goldgrab Do, Sokol Kalaveshi, Ruifang Yang Md, Jose Luis Henao, Stephen Mester Md, Christian Perzanowski Md

Cardiology

Introduction | Objectives: Radiofrequency ablation using wide area circumferential ablation (WACA) is the standard approach for paroxysmal atrial fibrillation (pAF). Invariably the posterior wall requires RFA to isolate the pulmonary veins (PV). However, excessive heating of the posterior wall can lead to catastrophic esophageal injury. It has been reported that pulmonary vein isolation can be achieved without fully encircling the PV antra. When WACA is not feasible then a semilunar/crescent lesion set (CL) limiting posterior wall ablation can be considered.

Methods:A non‐randomized prospective study comparing highly symptomatic patients with pAF who underwent WACA with a study group who had a …

Cardioversion Of Persistent Atrial Fibrillation Before High Energy Ablation Does Not Improve Outcomes In Short Term Follow Up: Preliminary Analysis, Ruifang Yang Md, Sokol Kalaveshi Md, David Goldgrab Do, Jose Luis Henao Md, Stephen Mester Md, Christian Perzanowski Md

Cardiology

Introduction | Objectives: The optimal approach of ablating persistent Atrial Fibrillation (peAF) has yet to be defined. By convention, mapping/ablation of peAF is most often performed in AF. The success of ablation hinges on catheter contact and achieving lesion transmurality. We theorized that ablation efficacy would improve during sinus rhythm (SR) given stability and predictability of catheter contact.

Methods: Non‐randomized comparison of peAF patients who underwent ablation in SR under a new practice protocol versus a cohort of peAF ablated in AF. The lesion set was the same for both groups, WACA ± BOX. Study group was treated with higher …
