Two Neutral IVUS Trials in Complex PCI—And One Positive—Spark Debate
Three recent randomized trials compared intravascular ultrasound (IVUS) with angiography for guiding complex percutaneous coronary interventions (PCI). Only DKCRUSH VIII, which focused on true bifurcation lesions, demonstrated a 60% relative reduction in 1‑year target‑vessel failure. The European OPTIMAL and IVUS‑CHIP studies, despite enrolling high‑risk left‑main and mixed complex lesions, showed neutral outcomes. Experts attribute the discrepancy to operator experience and the extent to which IVUS findings altered procedural technique, sparking debate over its routine use despite class 1A guideline recommendations.

Olezarsen Doesn’t Lower Plaque Volume: Essence-TIMI 73b
Olezarsen, an antisense drug targeting APOC3, dramatically lowered triglycerides (‑64 %) and remnant cholesterol (‑72 %) in the Phase III Essence‑TIMI 73b trial, yet a 12‑month coronary CTA subanalysis showed no significant reduction in non‑calcified plaque volume versus placebo. The study involved 468 patients...
