BACKGROUND: Effective regurgitant orifice area (EROA) in mitral regurgitation (MR) is
difficult to quantify. Clinically it is measured using the proximal isovelocity surface area …

Background: Recently, the automated cardiac output method (ACM) was introduced for the
calculation of blood flow at the left ventricular outflow tract (LVOT). This study was performed …

Hintergrund: Neben konventionellen echokardiographischen Doppler-Methoden, die nur
eine semiquantitative Schweregradabschätzung von Klappenregurgitationen erlauben, wird …

Background Clinical application of the color Doppler proximal isovelocity surface area
(PISA) method to quantify mitral regurgitation (MR) has been limited by the often inaccurate …

Common atrioventricular (AV) canal consist of a group of structural heart malformations that
share some common features but can vary widely with respect to anatomic features and …

The converging flow field proximal to a leaking valve is determined among other things by
the orifice inlet angle formed by the leaflets. Thus, the inlet angle affects the determination of …

Purpose: The aim of this study was to evaluate the reliability of mitral regurgitation color M‐
mode regurgitant flow propagation velocity (RFPV) in grading mitral regurgitation (MR) …

This study was designed to assess the reliability of the proximal isovelocity surface area
(PISA) method for the estimation of shunt quantification in perimembranous ventricular …

Mitral effective regurgitant orifice area (EROA) using the flow convergence (FC) method is
the current method of choice for quantifying the severity of mitral regurgitation (MR) …

Background: No data exist to indicate whether transthoracic (TTE) and transesophageal
echocardiography (TEE) are of comparable value for the detection and quantification of …
