INTRODUCTION: The safety of @entity1165 ( @entity1165 ) ablation in @entity1 with laminated left ventricular (LV) @entity715 has not been examined. METHODS: @entity1 with laminated LV @entity715 on transthoracic echocardiogram who underwent scar-mediated @entity1165 ablation at two centers from 2010-2013 were retrospectively analyzed. All @entity1 had failed medical therapy. Acute procedural outcomes, complications, and clinical outcomes at one year were assessed. RESULTS: Eight @entity1 (4 @entity63 , 4 @entity296 ) underwent @entity1165 ablation in the presence of laminated intracavitary @entity715 . Six out of 8 (75%) had @entity15262 ( @entity15262 ). The mapping and ablation approach was LV endocardial-only in 3 @entity1 , epicardial-only in 2, combined epicardial-RV endocardial in 2, and combined epicardial-LV endocardial in 1. Major complication ( @entity385 ) occurred in 1 @entity1 9 days post-procedure. There was no procedural mortality. Complete acute procedural success (noninducibility of any @entity1165 after ablation) was achieved in 5 (63%), and partial success (ablation of only clinical @entity1165 ) in an additional 3 (37%). At 1 year, freedom from @entity1165 and survival were achieved in 6 (75%) and 7 (88%) @entity1 , respectively. CONCLUSION: Initial data suggest ablation of @entity1165 in the presence of intracavitary @entity715 is feasible, is associated with a similar success rate to historical studies in @entity1 without @entity715 , and has an acceptable risk of complications given the high risk nature of @entity1 with @entity15262 . Further data is needed; however, the presence of a laminated @entity715 should not necessarily preclude ablation in @entity1 who have failed medical therapy for @entity1165 in whom ablation is otherwise indicated.
