A model for predicting the time of early symptomatic restenosis after infrapopliteal angioplasty in patients with critical limb ischemia.

The objective of this study is to develop a model for predicting the time of early symptomatic (delayed or nonhealing wound) restenosis after infrapopliteal angioplasty in patients with critical limb ischemia (CLI). This is a single-center retrospective cohort study evaluating 60 de novo infrapopliteal lesions of 38 limbs in 35 patients with CLI, who underwent successful endovascular treatment (EVT) from October 2016 to December 2018 and follow-up angiography within 3 months from the procedure. Outcome measures were binary restenosis at follow-up angiography and clinical outcome at 3 months.

Brachial-Ankle Pulse Waves Reflect the Hemodynamics of Valvular Heart Disease.

Background: Brachial-ankle pulse wave (ba-PW) analysis is an established technique for assessing arterial stiffness and cardiovascular risk. The peripheral arterial pulse wave configuration may be useful for valvular heart disease (VHD) detection because it is closely related to the physical signs of VHD; however, few reports have been made assessing the efficacy of ba-PW analysis for VHD screening.

Methods: Consecutive VHD patients scheduled for valve surgery were enrolled in the study.

Usefulness of peripheral arterial signs in the evaluation of aortic regurgitation.

Background: Early diagnosis and optimal timing of surgical repair for chronic aortic regurgitation (AR) are topics of interest, because left ventricular compensation delays the clinical signs of the early stages of left ventricular dysfunction. Various physical signs have been described as indicators of chronic AR, but AR screening can be difficult depending on the proficiency of primary care providers. The recent use of the cardio-ankle vascular index (CAVI) measurement to assess peripheral atherosclerosis may detect AR objectively and simply because its arterial pulse wave configuration is closely related to the physical signs of AR.
