BACKGROUND: The data supporting the practice of empiric slow pathway ablation (ESPA) in @entity1 with documented @entity4710 ( @entity4710 ) who are non-inducible at electrophysiology study (EPS) is limited. The aim of this study is to assess the efficacy of ESPA in adults. METHODS: A multi-center cohort study of @entity1 who had ESPA between January 2008 and October 2013 was performed. @entity1 were identified by screening sequential @entity4710 ablation procedures. RESULTS: Forty-three (5%) out of 859 @entity4710 ablation procedures were identified as ESPA. The median age was 53 (IQR: 24) years; 63% were female. All @entity1 had pre-EPS documentation of @entity4710 (either strip or ECG). In 23 (53.5%) cases, pre-EPS ECG showed short @entity591 . Thirty-two (74.4%) @entity1 had dual atrioventricular nodal physiology (DAVNP) plus echo beats. Junctional rhythm (JR) as procedural endpoint was noted in 39 (90.7%) @entity1 . In 18 (41.9%) @entity1 , the abolishment of DAVNP was achieved. No complications were encountered. A median follow-up of 17months (range: 6 to 31months) revealed 83.7% (36 of 43) success rate, defined as the absence of pre-procedural symptoms and any documented sustained @entity943 . As compared to @entity1 with recurrence (n=7), @entity1 with no recurrence (n=36) had significantly higher prevalence of clinical short @entity591 (61.1% vs. 14.3%, p=0.038), and EPS finding of DAVNP plus echo beats (80.6% vs. 42.9%, p=0.034). CONCLUSIONS: ESPA is a reasonable approach in @entity1 with documented @entity4710 , in particular in short @entity591 , who are not inducible at EPS. Larger studies are required to assess this practice.
