6. Baby J wire from sheath
7. 8 Fr dilator
8. 6 Fr Perclose pre-close RFV. .032 wire inserted after preclosure deployment.
9. TEE & fluoro guided transeptal access & images of Left Atrial Appendage
10. Anesthesia gives Heparin IV. ACT GOAL >250-300
11. Transeptal puncture
12. Measure LA pressure
13. 14 Fr WATCHMAN delivery sheath either SINGLE, DOUBLE or ANTERIOR Curve
14. 5 Fr Str Pigtail advanced to the LAA
15. Hook pigtail up to manifold for angiogram of LAA
16. Measure and select size of Watchman device
