Rationale

The 2025 ACC Scientific Statement provides updated clinical context for the use of PVR, particularly emphasizing its role in patients with diabetes where medial arterial calcification often renders the ABI unreliable. The rewrite integrates this specific clinical application while maintaining the original structure and expanding necessary abbreviations.

Content Changes

* Provides waveform analysis of volume changes.changes throughout the cardiac cycle.
* Flattened or dampened waveforms =indicate severesignificant peripheral arterial disease (PAD).(PAD) [@acc2025-d].
* Advantage: PVR is not affected by calcification.medial arterial calcification, making it a preferred diagnostic tool in patients with diabetes or advanced age where ankle-brachial index (ABI) measurements may be falsely elevated or non-compressible [@aha2016] [@rutherford2018-rutherford] [@acc2025-d].
