Rationale

The 2024 ACC/AHA/SVS/VESS Lower Extremity PAD guideline (PMID 38743805) directly supersedes the 2016 AHA guideline for the claim about PVR utility in patients with diabetes or non-compressible vessels where ABI may be unreliable. Per the stale guideline replacement instructions, Patel MR, et al has been replaced with AHA rather than co-cited, as both support the same claim and the newer guideline is the current authoritative source. The remaining citations are preserved unchanged.

Evidence

Gornik HL et al. 2024 ACC/AHA/AACVPR/APMA/ABC/SCAI/SVM/SVN/SVS/SIR/VESS Guideline for the Management of Lower Extremity Peripheral Artery Disease: A Report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines. Circulation. 2024. PMID: 38743805. DOI: 10.1161/CIR.0000000000001251.

Content Changes

* Pulse volume recordings (PVR) provide waveform analysis of segmental volume changes.
* Flattened or dampened waveforms indicate significant peripheral artery disease (PAD).
* Advantage: not affected by medial arterial calcification. This makes PVR particularly useful in patients with diabetes or non-compressible vessels where the ankle-brachial index (ABI) may be unreliable [@aha2016][@svs2024-gornik] [@rutherford2018-rutherford] [@acc2025-management].
