BACKGROUND: The two-dimensional (2D) proximal isovelocity surface area (PISA) method
has some technical limitations, mainly the geometric assumptions of PISA shape required to …

Background—It is unclear if mild or moderate mitral valve regurgitation (MR) should be
repaired at the time of coronary artery bypass grafting (CABG). We sought to determine the …

Abstract Objectives. We used color Doppler flow mapping to determine whether vena
contracta width (VCW) is a load-independent measure of the severity of mitral regurgitation …

Objectives. Mitral regurgitation (MR) is a common echocardiographic finding; however, there
is no simple accurate method for quantification. The aim of this study was to develop an …

Experimental flow field characterization is a critical component of the assessment of the
hemolytic and thrombogenic potential of heart valve substitutes, thus it is important to identify …

We evaluated 44 consecutive patients who underwent standard two‐dimensional (2D) and
live three‐dimensional (3D) transthoracic echocardiography (TTE), as well as left heart …

Purpose: To prospectively determine if retrospectively electrocardiographic (ECG)-gated
multi–detector row computed tomography (CT) with a 16–detector row CT scanner can …

Aims Peak cardiac power output-to-mass (CPOM) represents a measure of the rate at which
cardiac work is delivered respect to the potential energy stored in left ventricular (LV) mass …

BACKGROUND: Ischemic mitral regurgitation (IMR) is a complex lesion to repair, and its
successful management requires an understanding of its mechanism and severity. Ring …

Over the past 15 years there has been rapid and dramatic change in the therapy for valvular
heart disease. When mitral and aortic regurgitation are severe, they inevitably cause left …
