    The FDA AI/ML device list shows a newer 510(k) K190925 (decision 2019-08-15) from HeartFlow, Inc. for a matching device line ("HeartFlow FFRct Analysis") — a new clearance for the same line is a change event.

  • re_clearance

    The FDA AI/ML device list shows a newer 510(k) K182035 (decision 2018-12-06) from HeartFlow, Inc for a matching device line ("FFRct") — a new clearance for the same line is a change event.

Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device); a recall is shown as device-attributed only when the recall record itself lists this clearance number. Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-07-08.

Reimbursement — how devices like this got paid

Not yet tracked — no payment pathway indexed for this clearance (the reimbursement corpus is a growing seed set).

Applicable FDA guidance — what the submission is measured against

FDA guidance documents and guiding principles applicable to 510(k) AI/ML devices in the Cardiovascular panel. A curated reference index, not legal or regulatory advice — each item states its own status, and a draft is never binding.

Applicability is derived from the device's FDA advisory panel and pathway — cross-cutting guidances apply to every AI/ML device; panel-specific ones are flagged. Titles, dates, and links verified against fda.gov as of July 2026.
