Adjusting the cuff-based method for the additional femoral segment measured gives results comparable to the tonometer-based method, for which the majority of population data exist to date. This study provided validation of a cuff-based assessment of carotid-femoral pulse wave velocity against the universally accepted tonometric method. Abstract Simultaneous records of the pulse waves were obtained from the right common carotid artery and the right femoral artery by means of piezoelectric. The femoral artery, in a nondiseased state, is a larger caliber artery (permitting larger size catheters) and is less prone to spasm when compared. The adjusted cuff-based method gave similar results to the tonometer-based method ( P = 0.94), with no dependence upon age ( P = 0.46). Femoral access is still the most common mode of vascular access for coronary angiography and intervention in the United States, though transradial access is on the rise. The femoral artery should run obliquely through the corner of the pubic hair triangle inferior to the inguinal ligament at a point midway between the pubic. The lateral corners of the pubic hair triangle are observed and palpated. Analysis of covariance with age showed a difference between the tonometer and cuff-based methods ( P < 0.001), with a dependence upon age ( P = 0.004). The femoral pulse is evaluated with the patient lying on the back and the examiner at the patient's right side. With application of the algorithm, the cuff-based device gave similar pulse wave velocity values (7.04 ± 1.72 m/s) as the tonometer-based approach ( P = 0.86). The unadjusted cuff-based approach gave lower pulse wave velocity values than the tonometer-based approach (6.11 ± 1.27 and 7.02 ± 1.88 m/s, P < 0.001). Comparison was made by Bland–Altman and regression analysis.
Method:Įighty-eight individuals were recruited across four centres and carotid-femoral pulse wave velocity measured in triplicate using two operators with both a tonometer-based device and a device using an inflated thigh cuff with and without the use of the novel algorithm. A novel algorithm to correct for the transit time and distance related to the additional femoral segment was applied to the cuff-based approach in this study. Leg cuff detection of the femoral pulse removes the need for signal gating, reduces the time required for a single measurement, but gives different pulse wave velocity values to tonometric analysis. Combined data from UNOS and PHIS over 30 years show promising outcomes for these patients, including low rates of bronchiolitis obliterans syndrome and improved long-term survival in recent years.
