PWI PVI: helpful or not?
Both sides are “right” - because we’re asking the wrong question.
PWI likely works in a subset of patients.
Randomizing everyone → neutral trials.
The real question: who actually benefit from PWI?
We’ll address this at #HRS2026

The passing of David Haines is heartbreaking. David was not only an exceptional scientist, innovator, and a mentor, but also a genuinely humble, honest, and compassionate man. For Liz and I, David and Gail were true friends. His absence will be profoundly felt.
