Dylan Harper has the 3rd-best rim FG% (65.5%) of any guard in the playoffs since 2000. *min. 80 attempts* He is a rookie. Stephon Castle has the 4th-best (64.9%) – and at 21 years old, is the second-youngest on this list behind Harper.

Told ya. The NBA's Last 2 Minute Report confirms the out of bounds whistle on Stephon Castle was INCORRECT. In addition, NBA writer @TomerAzarly received confirmation from the league that Josh Hart should have been whistled for a foul on the Castle drive. Down 105-104 with 1:02 remaining, the Spurs were already in the bonus and the correct call would have given Castle a golden opportunity to take the lead with two massive free throws.

The #VoltPFA insights keep coming! Late-breaking results on Volt PFA System PVI durability and patterns help answer the question: does the pulse field ablation system matter? Explore the data straight from #HRS2026 ⬇️ Safety Info: bit.ly/4vHc0tl

Challenging 3D VT ablation where pt had previously undergone two ablations including bipolar RF and dual energy on another mapping system. Extensive endo and epicardial mapping and long endocardial lesions resulted in VT termination and noninducibility. #3DVT #intramuralsubstrate

The problem is not the ablation method thermal or non-thermal, RF or PFA. As with WACA, the real issue is that you can’t truly demonstrate transmurality. Moreover, the posterior wall is particularly challenging due to the thick septopulmonary epicardial fibers.

What’s the obsession with PWI in AF ablation? It may appear “safe & easy” ⁦@drjohnm⁩ BUT no randomised evidence & there is downside #TWIC Oct 10

Great talk @DJ_Lakkireddy on important limitations of PFA outside of the veins. Single digit long term durability in La Fazia et al. Dual energy sources can’t come soon enough for redo ablations. There need not be discussions with current PFA iterations for VT. ahajournals.org/doi/10.1161/…

Awesome case and ILAM map narrowing our ablation target. From being induced with singles to non-inducible at triples, great outcome.
