@PennEPFellows is a surreal experience. When you see the master @DavidCallans step up to the calipers during a challenging case presented by Danish Zaidi, MD, you realize how special this place is to learn. Truly a place like no other in the world. @PennCardiology

Looking forward to the discussion.

FYI / OPTIMAL AF-HF was actually created based on a panel discussion on the next HF trials that I participated in at #WAFIB.

Following that presentation @DrRoderickTung and myself sat down and designed the OPTIMAL AF-HF study.
