Top Stories / Major Trials
- CHAMPION-AF (NEJM simultaneous publication, ACC.26): Watchman FLEX LAAC non-inferior to NOACs for stroke/CV death/systemic embolism (5.7% vs 4.8%) in 3,000 AF patients; major bleeding halved (10.9% vs 19%, HR 0.55). Net clinical benefit favors device. Skepticism note: Large trial, high procedural success (98.8%), but long-term durability and real-world anticoagulation adherence post-LAAC need monitoring; not yet superiority.
- HI-PEITHO (ACC.26): Ultrasound-facilitated catheter-directed thrombolysis vs anticoagulation alone in intermediate-high-risk PE; functional and hemodynamic gains at 90 days. Practice impact: Supports earlier interventional strategy in select PE; watch for full publication and bleeding signals.

- **Top Stories / Major Trials**
  - VESALIUS-CV (evolocumab primary prevention): 25% relative risk reduction in 3-point MACE (6.2% vs 8.0%) and 19% in 4-point MACE in high-risk patients (atherosclerosis or diabetes, no prior MI/stroke); LDL-C dropped to ~52 mg/dL; practice impact: supports earlier PCSK9i use, but watch for cost/access; no new safety signals (NEJM 2026).
  - CHAMPION-AF (Watchman FLX LAAC vs NOAC): Non-inferior efficacy (5.7% vs 4.8%), superior bleeding reduction (10.9% vs 19%); ischemic stroke slightly higher with device—skeptical of broad first-line shift pending longer data.
  - SURPASS-CVOT (tirzepatide vs dulaglutide): Non-inferior for MACE in T2DM + ASCVD (12.2% vs 13.1%); GI side effects higher; reinforces dual GIP/GLP-1 role.
  - ACC.26 Interventional: Mixed IVUS results—superior in DKCRUSH VIII bifurcations (TVF 6.1% vs 14.7%) but neutral/inferior in IVUS-CHIP complex PCI and OPTIMAL left main; tempers routine imaging enthusiasm—operator expertise and optimization criteria key; STEMI-DTU LV unloading neutral with more bleeding.

- **Guideline & Consensus Updates**
  - 2026 ACC/AHA Multisociety Dyslipidemia Guideline (March 13, 2026; replaces 2018): Restores LDL-C goals (<55 mg/dL very high-risk, <70 mg/dL high-risk); routine one-time Lp(a) testing (≥125 nmol/L enhancer); PREVENT-ASCVD risk equations; apoB for residual risk; CAC for uncertain cases; ezetimibe/PCSK9i/bempedoic sequencing clarified; pitavastatin for HIV (REPRIEVE); no routine CK monitoring—major practice shift for primary prevention and Lp(a).
  - 2026 HRS/AHA/APHRS/EHRA/IDSA/LAHRS/PACES/STS CIED Lead Management Consensus (April 25, 2026): Holistic lifelong strategy, extraction thresholds, patient-centered decisions; reduces complications via shared decision-making.

- **Device & Procedural News**
  - Philips AI DeviceGuide FDA clearance (March 2026): Real-time guidance for complex transcatheter valve repair—potential to improve precision in TAVR/TEER.
  - Boston Scientific: WATCHMAN FLX CHAMPION-AF data; EKOS HI-PEITHO superior for intermediate-risk PE (61% event reduction, shorter stays).
  - New stroke-prevention devices for TAVR: Head-to-head with Sentinel (March 2026).

- **New Drugs & Therapeutics**
  - Evolocumab expansion via VESALIUS-CV subgroup (diabetes primary prevention): HR 0.69 for MACE; aligns with guideline push for aggressive LDL lowering.
  - Tirzepatide CVOT confirmation: Broadens dual agonist use in ASCVD.
  - Bempedoic acid: CLEAR Outcomes integration for statin-intolerant; MACE benefit confirmed.

- **Imaging & Diagnostics**
  - CAC scoring elevated in dyslipidemia guideline for borderline/intermediate risk; guides deferral or intensification.
  - ApoB and Lp(a) routine integration; Martin/Hopkins equations preferred for LDL estimation.
  - Skepticism note: IVUS trials show inconsistent benefit—prioritize lesion-specific optimization over blanket adoption.

- **Practice-Changing Insights**
  - Dyslipidemia guideline + VESALIUS-CV: Shift toward earlier non-statin add-ons and Lp(a) screening for busy cardiologists; reduces events but requires cost-benefit discussion.
  - Interventional caution: Avoid over-reliance on IVUS in all complex PCI; focus on proven subsets (bifurcations).
  - Device approvals accelerate AI integration in procedures.

- **Appended New Updates / Corrections (as of May 8, 2026)**
  - No major corrections published; VESALIUS-CV full results emphasize diabetes subgroup benefit (JAMA 2026); guideline implementation tools now available via ACC.
  - Ongoing: Watch for inclisiran CVOTs and long-term LAAC stroke data.

**Top Stories / Major Trials**
- CHAMPION-AF (ACC.26, NEJM): WATCHMAN FLX LAAC noninferior to NOACs for 3-year CV death/stroke/systemic embolism in nonvalvular AF (5.7% vs 4.8%, p<0.001 noninferiority); superior bleeding safety (10.9% vs 19%, HR 0.55). Watch for slight excess ischemic stroke signal (3.2% vs 2.0%).
- HI-PEITHO (ACC.26, NEJM): EKOS ultrasound-assisted catheter-directed thrombolysis + anticoagulation superior to anticoagulation alone for intermediate-risk PE (4.0% vs 10.3% primary endpoint at 7 days, 61% relative reduction); shorter ICU/hospital stay, no excess major bleeding.
- VESALIUS-CV (ACC.26, NEJM): Evolocumab in primary prevention (elevated LDL-C, atherosclerosis/diabetes, no prior MI/stroke) reduced 3-point MACE (6.2% vs 8.0%, HR 0.75) and 4-point MACE (HR 0.81). Strongest evidence yet for PCSK9i in this population.
- STEMI-DTU (ACC.26): Impella LV unloading before PCI in anterior STEMI without shock missed primary infarct-size endpoint (1% absolute reduction, not statistically significant); safe but no clear clinical win—skeptical of broad adoption pending larger data.
- IVUS-CHIP/DKCRUSH VIII/OPTIMAL (ACC.26): Mixed intravascular imaging results in complex PCI; some trials showed no benefit or higher events vs angiography guidance—caution against routine use without patient selection.

**Guideline & Consensus Updates**
- 2026 ACC/AHA Multisociety Dyslipidemia Guideline (March 13, 2026; replaces 2018): Introduces Lp(a) measurement at least once; graded risk at ~125 nmol/L; restores LDL-C goals by risk; emphasizes exercise, diet, and cautions on supplements. Early screening and add-on testing highlighted.
- 2026 HRS/AHA/APHRS/EHRA/IDSA/LAHRS/PACES/STS CIED Lead Management Consensus (April 25, 2026): Updates extraction indications, leadless tech integration, lifelong management; focuses on reducing complications with newer CIEDs.

**Device & Procedural News**
- FDA approvals (April 2026): Biotronik Acticor/Rivacor Sky ICD/CRT-D family with LBBAP support and advanced ATP; Stereotaxis MAGiC robotic ablation catheter for complex arrhythmias; Medtronic Mosaic Neo next-gen mitral bioprosthesis.
- PFA systems: At least three gaining FDA approval in prior year; rapid adoption for AF ablation with shorter procedures.
- Structural: Ongoing expansion of TEER (TRILUMINATE), EVOQUE tricuspid replacement, Tendyne TMVR; PROTECT H2H embolic protection in TAVI.

**New Drugs & Therapeutics**
- Tirzepatide (SURPASS-CVOT, ACC.26): Noninferior to dulaglutide for CV outcomes in T2DM+ASCVD; more GI side effects.
- Finerenone: First robust HFpEF benefit (FINEARTS-HF) across EF spectrum; 16% reduction in CV death/worsening HF; low hyperkalemia hospitalization rate—potential new pillar.
- Emerging: Lp(a) lowering agents in late trials (approval likely 2026-27 if outcomes confirm); enlicitide (oral PCSK9i) CORALreef positive.

**Imaging & Diagnostics**
- AI/voice: Mayo Heart & Voice study for remote HF monitoring; 98 AI cardiology devices FDA-cleared.
- CardioMEMS: Expanded FDA clearance and Medicare coverage for broader HF use.

**Practice-Changing Insights**
- LAAC may shift to first-line in select AF patients (CHAMPION-AF safety edge).
- Physiology/imaging-guided complete revascularization in ACS: Benefit even in high-bleeding-risk; default strategy emerging.
- Conduction-system pacing (LBBAP): Lower complications and HF hospitalizations vs BiV in CRT candidates—watch for guideline inclusion.

**Appended: New Updates & Corrections (as of May 7, 2026)**
- No major post-ACC.26 corrections identified; VESALIUS-CV and CHAMPION-AF publications confirm primary results. Dyslipidemia guideline emphasizes avoiding nonprescription fish oil without benefit data. Ongoing trials (e.g., Lp(a) outcomes) flagged for future impact.
