10. .035 J wire removed, VersaCross RF pigtail wire advanced for transeptal puncture.
11. TEE & fluoro guided transeptal access & images of Left Atrial Appendage
12. Anesthesia gives Heparin IV. ACT GOAL >250-300
13. Transeptal puncture, ACT drawn from LA.
14. Measure LA pressure
15. 15 Fr WATCHMAN delivery sheath either SINGLE, DOUBLE or ANTERIOR Curve
16. Backloaded 5 Fr Str Pigtail advanced to the LAA
