The Valve Wire

Thursday, September 17, 2026

Executive Summary

CMS finalized its updated TAVR National Coverage Determination — the single most consequential US structural heart policy action of the year — alongside a Czech national registry in the International Journal of Cardiology reporting 1.3% cumulative TAVI endocarditis incidence with 27% in-hospital mortality across 9,887 procedures. A separate Heart Rhythm analysis reframes the persistent 16% TAVR pacemaker rate as an anatomy problem: centers using membranous-septum-guided depth control have driven pacing to 3-5%. Edwards told the Street its TMTT franchise is a $2B opportunity on top of continued TAVR expansion, tightening the coverage-plus-durability question the ESC 2025 guidelines already put on the table.

  • Czech nationwide TAVI registry: 1.3% endocarditis incidence, 27% in-hospital mortality, Enterococcus faecalis the dominant pathogen (29%) (Int J Cardiol).
  • Membranous-septum-guided TAVR depth control drops pacemaker rates from 16% to 3-5%, with 25% higher pacing odds per mm implanted below the His bundle (Heart Rhythm).
  • Disproportionate FMR is a morphology problem, not just an LV problem — pseudo-prolapse, extreme annular dilation, and deep indentation predicted residual MR after TEER (N=114, single-center, non-randomized) (Circ J).
  • Transjugular LuX-Valve Plus TTVR succeeded in a giant-right-atrium anatomy with 55.5 mm elliptical annulus previously unsuitable for TEER or redo surgery (EHJ Case Rep).
  • Boston Scientific down 39% over six months, an outlier against Edwards (+6%) and Medtronic (+7%), reframing the structural heart competitive map (MarketBeat).

What to watch: Edwards Q3 earnings on October 29 will be the first quarterly print after the finalized NCD and will test whether TMTT growth is tracking to the $2B narrative.


Aortic Valve (TAVR/TAVI)

TAVR pacemaker rates are an anatomy problem, and the field has known how to fix them for years. The Heart Rhythm commentary from Jilaihawi, Ellenbogen, Vijayaraman, and Makkar makes an uncomfortable point: contemporary multicenter TAVR pacing rates sit near 16%, but single-center programs using membranous-septum-length-guided implantation depth have driven that to 3-5%, with a 25% increase in pacing odds per millimeter of implantation below the estimated His bundle. That gap is not a device limitation — it is a workflow and imaging discipline gap. ACC/AHA 2020 and ESC 2025 both list new pacemaker requirement as a factor in the SAVR/TAVI shared decision; for context, the surgical literature reports 6.5% third-degree AV block after SAVR in bicuspid AS patients, so the TAVI-versus-surgery delta narrows materially once TAVR centers perform the CT reconstruction work that membranous-septum guidance requires.

The Czech nationwide registry (9,887 TAVIs, 2010–2023) reports a 1.3% cumulative endocarditis incidence with 27% in-hospital mortality, and Enterococcus faecalis as the dominant pathogen (29%). The pathogen profile is a warning: enterococcal IE post-TAVI implies GI/GU source translocation in a population where surgical rescue is often not viable. Contemporary surgical AVR endocarditis rates in comparable registries run 0.5–1.0%/year; the durability comparison with SAVR is not settled once IE risk is folded over 10-year horizons in patients who are increasingly under 70. ESC 2025 sets SAVR as preferred below age 70 on low surgical risk; ACC/AHA 2020 draws that line at 65. The infection data argue for caution in pushing TAVI younger.

CMS finalized the updated TAVR NCD, and a companion Spanish commentary asked whether TAVI in centers without on-site cardiac surgery is "need or dare." Coverage expansion without a surgical safety net is a familiar tension — ESC 2025 explicitly requires Heart Team infrastructure, and the endocarditis data above make the surgical rescue argument more concrete. A rare acquired iTTP case after transaxillary TAVR (Cureus) is a reminder that unexplained post-TAVR thrombocytopenia with hemolysis is not always benign.


Mitral Valve (MitraClip, PASCAL, TMVR)

Disproportionate FMR is a morphology diagnosis, and it explains residual MR after TEER better than LV size alone. The Japanese TEER cohort (N=114, single-center, non-randomized) split patients by EROA/LVEDV ratio and found that disproportionate FMR patients had higher prevalence of pseudo-prolapse (28.8% vs 8.3%), extreme mitral annular dilatation >700 mm²/m² (53.0% vs 29.2%), and deep indentation (24.2% vs 4.2%). The number of morphological factors predicted disproportionality after adjustment (OR 4.15). This is the mechanistic bridge between COAPT and MITRA-FR the field has been reaching for — disproportionate MR is not just "small LV, big regurgitation" but a leaflet-annular phenotype where TEER is liable to leave meaningful residual MR.

The ESC 2025 upgrade of TEER for ventricular SMR to Class I (from ACC/AHA IIa) assumes COAPT-like patient selection. This Circulation Journal analysis argues the selection filter must add leaflet morphology, not just LVESD ≤70 mm and EROA thresholds. Surgical mitral repair for degenerative disease with pseudo-prolapse and deep indentations remains the durable answer at experienced centers — the ESC 2025 Class I upgrade for early repair in asymptomatic PMR with adverse features raises the bar TEER has to clear when anatomy is unfavorable.

A JACC Case Reports series describes three-clip TEER downgrading severe degenerative MR to trace in an 80-year-old with coexisting cor triatriatum sinistrum — feasibility, not a practice change, but a marker of how far anatomically prohibitive cases now travel through the transcatheter pathway.


Tricuspid Valve (TriClip, TTVR)

TTVR is expanding into anatomies that would have been declined a year ago. The European Heart Journal Case Reports LuX-Valve Plus case describes a transjugular tricuspid replacement in a 62-year-old with a giant right atrium (11.59 × 7.73 cm), a 55.5 mm elliptical annulus, and a 79.2 mm bend-point-to-annulus distance that exceeded the device's proposed 45–70 mm range. The patient had prior mechanical mitral replacement and TAVR, and TEER was ruled out. NYHA IV improved to II at one month. Single case, industry-adjacent device, no comparator — but the boundary of what "torrential TR" means for candidacy is moving, and not all of that movement is supported by durability data beyond two years.

ESC 2025 placed transcatheter tricuspid treatment at Class IIa based on TRILUMINATE, Tri.Fr, and TRISCEND II; ACC/AHA 2020 addressed it not at all. Surgical isolated TV mortality historically ran 8–20%, and ESC 2025 upgraded symptomatic primary TR surgery to Class I precisely because late referral — not surgery itself — was the problem. The KSMC announcement of the first tricuspid valve replacement in MENA underscores that geographic diffusion is outpacing the RCT base, and durability for TTVR remains unanswered beyond two years.


Surgical vs. Transcatheter Comparisons

No head-to-head trials today. The Czech TAVI endocarditis data (1.3% cumulative, 27% mortality) reframe the durability conversation directly: surgical AVR remains the reference for younger patients under ESC 2025 (<70) and ACC/AHA 2020 (<65) partly on the strength of a known infection risk profile and the surgical rescue option TAVI increasingly lacks. The Japanese TEER morphology paper cuts the other direction — surgical MV repair for degenerative MR with pseudo-prolapse and deep indentations is more durable than TEER, a reality the ESC 2025 Class I early-repair upgrade already codified.


Device & Technology

A Europace paper mapped transaortic pacing targets for valve-integrated pacemakers — the concept of a pacing-capable TAVR platform is moving from concept to electrophysiologic mapping. If pacing is required in 16% of contemporary TAVR patients (per the Heart Rhythm analysis above), integrating it into the valve rather than adding a separate device changes the workflow calculus substantially. A quasi-experimental Chinese study reported that a multidisciplinary ERAS pathway with an information platform shortened TAVR hospitalization and improved functional recovery (N=154, single-center, historical control). Signal, not proof.


Regulatory & Policy

The finalized CMS TAVR NCD is the headline regulatory event. The ACC's coverage frames the update as expansion; the operational question is whether volume thresholds and Heart Team requirements loosened. Read the final rule end-to-end — press summaries have not been sufficient for prior NCD cycles and will not be here.


Industry & Market

Edwards told analysts at Deutsche Bank's Healthcare Summit that it sees continued TAVR expansion and a $2B TMTT opportunity, with the stock up 4.1% on the day. The TMTT franchise thesis rests on PASCAL, EVOQUE, and SAPIEN M3 — all platforms the ESC 2025 Class IIa transcatheter tricuspid recommendation leans on. Medtronic hired Recor Medical's ex-CEO Lara Barghout, adding renal denervation leadership to a company still working through its Evolut low-risk narrative.


Financial Analysis

The market split within structural heart is stark: Edwards +6% over six months, Medtronic +7%, Abbott -7%, Boston Scientific -39%. The BSX drawdown does not match its clinical footprint — Boston Scientific's structural heart pipeline is not weakening, and the stock's 39% collapse from $71.94 to $43.31 reflects concerns outside the valve franchise. Edwards' TAVR-plus-TMTT narrative, endorsed by a 4.1% rally on the day the CMS NCD finalized, is the cleanest read-through: coverage clarity plus a specific $2B tricuspid/mitral revenue path. The clinical underpinning matches — ESC 2025 Class IIa for transcatheter tricuspid opens the reimbursement pathway Edwards is building toward.

Market outlook: The finalized CMS TAVR NCD removes a policy overhang for the entire aortic transcatheter franchise. Edwards has consolidated the narrative — tricuspid and mitral are the growth vector, aortic is the base. Medtronic's Evolut position is stable but not accelerating. Abbott and Boston Scientific are trading disconnected from their clinical footprints, which sets up either a re-rating on Q3 prints or continued divergence. Note: JenaValve Technology, J Valve Technology, and Meril Life Sciences are private companies (no public stock data).


Clinical Trial Updates

Aortic / Structural (mixed):

  • NCT07825246 — Development and Clinical Validation of a Smart Analysis System for a Wearable Cardiac Ultrasound Device. Status: Not yet recruiting. Phase NA. Enrollment 600. Sponsor: Kunjing Pang. Wearable ultrasound-based cardiac monitoring is an emerging category with implications for asymptomatic AS surveillance if it can reliably track gradient progression.
  • NCT07826078 — TORCH-LATAM-004: Regional Advanced-Therapy Pathways for Adults With Acquired or Structural Heart Disease. Status: Not yet recruiting. Phase NA. Enrollment 360. Sponsor: CardioVision International Tech. A Latin American pathway trial addressing access to advanced structural heart therapies — the same geographic diffusion problem the KSMC MENA announcement illustrates.

Social & Conference Highlights

The Manipal Hospital Dhakuria MitraClip case in an 80-year-old and the KSMC first-in-MENA TTVR both signal that structural heart is entering the "prestige case announcement" phase in emerging markets — a leading indicator of demand build-out.


Forward look: Edwards Q3 on October 29 is the pressure test — the market has already priced the CMS NCD and the TMTT narrative, and the print needs to show tricuspid and mitral revenue lines that make the $2B target plausible.
