Normal aging in man is known to be associated with a reduction in left-ventricular diastolic function, including the rates of relaxation and filling. Calcium channel blockers have been reported to improve left-ventricular diastolic function in patien

To determine which factors may affect the image quality when an intravascular ultrasound catheter is used in vivo, the influence of blood, temperature change, and contrast media were evaluated. In addition, to confirm the reproducibility of intravasc

A method to assess the degree to which an atheroma plaque has been disrupted by percutaneous interventional methods could be of considerable benefit. An intravascular ultrasound catheter could provide quantitative information about the distribution a

A prototype intravascular ultrasound imaging catheter with a 20 MHz transducer was used to obtain 59 cross-sectional images in 14 segments of human atherosclerotic arteries. Three distinct components of the arterial wall were visualized on the ultras

This manuscript describes a new method, validated in in vitro models, for quantitating volume flow rate across an orifice with Doppler color flow mapping. Flow through a narrowed orifice is characterized by the convergence of radial streamlines proxi

To evaluate the mechanism of excimer laser recanalization and compare the results with those of laser-assisted thermal probe recanalization and mechanical recanalization, a total of 42 human atherosclerotic totally occluded arterial segments (2–15
