To evaluate the diagnostic performance of 16-section multidetector computed tomography (CT) for assessment of plaques in phantoms and ex vivo coronary arteries, with intravascular ultrasonography (US) and optical coherence tomography (OCT) as referen

Three alternative methods have been proposed for determining the "velocity of propagation" (V(p)) from color M-mode Doppler transmitral flow images. A quantitative intermethod comparison is performed by using a broad class of images encountered in cl

Abnormalities of diastolic function (DF) precede systolic dysfunction in diabetic cardiomyopathy. Transmitral Doppler flow analysis is the primary method for noninvasively assessing DF. We used model-based Doppler E-wave analysis to evaluate diastoli

A chamber stiffness ( KLV)-transmitral flow (E-wave) deceleration time relation has been invasively validated in dogs with the use of average stiffness [(ΔP/ΔV)avg]. KLVis equivalent to kE, the (E-wave) stiffness of the parameterized diastolic fill

We sought to extract additional physiological information from the time-dependent left ventricular (LV) pressure contour and thereby gain new insights into ventricular function. We used phase plane analysis to characterize high-fidelity pressure data

A calcified nodule is a type of potentially vulnerable plaque accounting for approximately 2% to 7% of coronary events. Because its intravascular ultrasound (IVUS) features have never been validated, the aim of this study was to assess the IVUS chara

A catheter-based near infrared spectroscopy (NIRS) system has recently been cleared by the FDA for detection of lipid core containing plaques of interest (LCP) and lipid core burden index (LCBI) in patients undergoing coronary arteriography. NIRS dat

InfraReDx has developed a spectroscopic cardiac catheter system capable of acquiring near-infrared (NIR) reflectance spectra from coronary arteries in vivo for identification of lipid-rich plaques of interest (LRP). The spectral data are analyzed wit
