A novel method to risk stratify patients undergoing exercise stress echocardiography using a set of combined criteria.

Background and Purposes A novel method using quantitative long-axis function and tissue Doppler in addition to wall motion analysis in exercise stress echocardiography was evaluated. We hypothesized that the novel criteria added additional accuracy in stress echocardiography. Methods Patients with chest pain and at low-to-intermediate risk for obstructive coronary artery disease (CAD) were retrospectively studied.

A novel method to quantify carotid artery stenosis by Doppler ultrasound: Using the continuity principle.

Background And Purpose: A novel method to quantify carotid artery stenosis by using the continuity principle was evaluated. It was hypothesized that the novel method improved the accuracy of carotid ultrasound in assessing carotid artery stenosis.

Methods: Forty-nine patients were retrospectively studied.

Diagnostic accuracy of 64 multidetector computed tomographic angiography in peripheral vascular disease.

Background: Previous studies of multidetector CT (MDCT) of the lower extremities for the detection of peripheral vascular disease showed high diagnostic accuracy but were performed with older generation systems.

Objective: The purpose of this study was to evaluate the diagnostic accuracy of 64 MDCT for the detection of hemodynamically significant disease within the lower extremity peripheral vasculature as compared to digital subtraction angiography (DSA).

Methods: Twenty-eight consecutive patients with symptomatic lower extremity intermittent claudication and an abnormal ankle-brachial index (ABI; less than 0.

A novel method of coronary stent sizing using intravascular ultrasound: Safety and clinical outcomes.

Objectives: The use of intravascular ultrasound (IVUS) in guiding coronary stenting has increased in recent years. The feasibility, safety and clinical outcomes of a novel method of sizing coronary stents using IVUS have not been established. The main end points of the current study are the incidence of acute and short-term complications, and the need for target vessel revascularization at six months.
