Although a less common origin, muscle fiber transitions along valve leaflets can cause focal AT. This case mapped with #HDGrid to superior mitral annulus. RF ablation terminated tachycardia in 2 seconds. @sanghaimdahajournals.org/doi/10.1161/…
Slow pathway mapped in sinus corresponded to earliest A mapped in tach to find ideal location for ablation. VOD performed and analyzed to confirm atypical AVNRT with pseudo VAAV response #PMA
Left-atrial flutter (CL 265ms) mediated by leak in prior roof line. Tachycardia terminated with 1 RF application at critical isthmus localized with #HDGrid#EnsiteX
