  • Cardio-ankle vascular index (CAVI) as an indicator of arterial . . .
    where K is the elastic modulus of luminal volume change per unit length of artery and ρ is the density of blood On the other hand, arterial stiffness can be defined by its distensibility, or preferably “compressibility”,27 which is the relative change in volume in response to a change in blood pressure That is: Compressibility = (ΔV V) ΔP, where ΔV = change in volume; V = original
  • Clinical Outcomes After Caval Valve Implantation for Severe Symptomatic . . .
    Caval valve implantation (CAVI) is a rapidly evolving transcatheter strategy to treat severe symptomatic tricuspid regurgitation (TR) in patients with right-sided cardiac failure and unsuitable anatomy for transcatheter edge-to-edge repair or orthotopic tricuspid valve replacement while being at high or prohibitive surgical risk for surgery 1,2 Available high-quality evidence regarding the
  • Significance of CAVI as a Functional Stiffness Parameter:
    Introduction Cardio-ankle vascular index (CAVI) is an arterial stiffness parameter that includes the entire arterial tree from the aortic valve to the tibial artery and is derived from stiffness parameter β 1 CAVI has been theoretically and clinically proven to be independent of blood pressure (BP) at the time of measurement, a characteristic not found in conventional parameters
  • Assessment of Arterial Stiffness Using the Cardio-Ankle . . . - PubMed
    The primary aims of assessing arterial stiffness using CAVI are to assist in the early detection of arteriosclerosis, allowing timely treatment and lifestyle modification, and to quantitatively evaluate the progression of disease and the effectiveness of treatment Whether CAVI-guided therapy can im …
  • The Background of Calculating CAVI: Lesson from the Discrepancy Between . . .
    Arterial stiffness is a good predictor of cardiovascular events As a substitute for elastic modulus representing stiffness, pulse wave velocity (PWV) has been used for over a century as it is easy to measure; however, PWV is known to essentially
  • Journal of Hypertension - LWW
    Schematic representation of the algorithm used in the calculation of the heart-to-ankle pulse wave velocity, which is the basis of both cardio-ankle vascular index and CAVI 0 The heart-to-ankle transit time is determined as the sum of the transit time between the second heart sound, corresponding to the closure of the aortic valve, and the dicrotic notch in the brachial artery pressure (P
  • Cardio-ankle vascular index (CAVI) measured by a new device: protocol . . .
    CAVI integrates information about the elasticity of blood vessels and represents a novel parameter of vascular stiffness that does not depend on BP 14 The mathematical expression to calculate CAVI values is described elsewhere 9 14 and is mainly based on substituting the stiffness parameters β and PWV in the following equation: β=2ρ×1 (SBP– DBP)×ln (SBP DBP)×PWV 2, where ρ is the
  • Cardio-ankle vascular index (CAVI) as an indicator of arterial stiffness
    Cardio-ankle vascular index (CAVI) as an indicator of arterial stiffness Cheuk-Kwan Sun Department of Emergency Medicine, Department of Medical Education, E-Da Hospital, I-Shou University, Kaohsiung, Taiwan Abstract: Arterial stiffness has been identified as an independent predictor of prognostic outcomes for patients with cardiovascular disease Although measurement of pulse wave velocity has
  • Cardio‐ankle vascular index and cardiovascular disease: Systematic . . .
    The cardio-ankle vascular index (CAVI) is a new measure of arterial stiffness that reflects the stiffness from the ascending aorta to the ankle arteries, and demonstrates little dependence on blood pressure during the evaluation
  • Caval Valve Implantation (CAVI): An Emerging Therapy for Treating . . .
    Severe tricuspid regurgitation remains a challenging heart-valve disease to effectively treat with high morbidity and mortality at mid-term Currently guideline-directed medical treatment is limited to escalating dose of diuretics, and the rationale and timing of open-heart surgery remains controver …
