OBJECTIVE: The feasibility and accuracy of direct transthoracic 3-dimensional (3D) mitral
valve area (MVA) measurements obtained using freehand scanning was investigated in …

Objective: This study aims to assess changes in mitral regurgitation (MR) severity after
transcatheter aortic valve implantation (TAVI). Background: Existing data on MR after TAVI …

Quantitation of valvular regurgitation remains an important goal in clinical cardiology. It has
been described previously that with the use of color Doppler flow mapping, simple …

Objectives. The goal of this study was to develop an accurate, simplified proximal isovelocity
surface area (PISA) method for calculating volume flow rate using lower blue-red interface …

Objectives To determine whether the combination of transesophageal echocardiography
(TEE) and contrast echocardiography (CE) accurately diagnose suspected cardiac masses …

To define the clinical utility of the color Doppler proximal isovelocity surface area (PISA)
method for estimating regurgitant stroke volume (SV), 160 regurgitant lesions were …

Valvular heart disease primarily affects the aortic and mitral valves due to higher left-sided
heart pressures, often leading to complications like leaflet calcification (stenosis), which …

A computer algorithm has been developed for segmentation and three-dimensional (3D)
reconstruction of Doppler color-flow images. The algorithm enables the user to select a …

Objectives. The objective was to analyze the accuracy and diagnostic value of the estimated
regurgitant volume of mitral regurgitation using 1) left atrial volume variation during …

The proximal isovelocity surface area (PISA) method for calculating volume flow through the
regurgitant orifice has attracted significant attention. A number of in vitro studies and clinical …
