The #1 Watchman implanter in the world Tom Waggoner gives an overview of his experience with WATCHMAN FLX PRO as well as tips and tricks for growing your watchman program.
Highlights:
* Hemocoat technology designed to reduce DRT (70% reduction in thombus at 14 days, 50% increased endothelial coverage at 45 days)
* Trial ongoing to investigate potential single anti-platelet therapy with new device
*Reduce untreatable LAA's with 40 mm device (6% previously untreatable now treatable)
* Fluoroscopic markers at shoulders to facilitate tug test and identify device position
* Tom uses smaller TEE probe (57% smaller diameter) to do procedures with conscious sedation
* Tom stops blood thinner at 90 days and images at 120 days to catch DRT (CHAMPION AF protocol)
* Tom discusses his outreach strategy and how he uses patient-facing symposiums on the weekend to grow volume
