Measurement of Left and Right Atrial Volume in Patients Undergoing Ablation for Atrial Arrhythmias: Comparison of a Manual versus Semiautomatic Algorithm of Real Time 3D Echocardiography

Aims Real time full‐volume 3D echocardiography (3DE) allows rapid and noninvasive measurement of left (LA) and right atrial (RA) volume without geometric assumptions. Different algorithms from different commercial providers are available. Older software requires manual tracing of endocardial contour...

Description
Summary:Aims Real time full‐volume 3D echocardiography (3DE) allows rapid and noninvasive measurement of left (LA) and right atrial (RA) volume without geometric assumptions. Different algorithms from different commercial providers are available. Older software requires manual tracing of endocardial contours. Recently, software with semiautomatic endocardial contour‐finding algorithms has become available, which considerably speeds up the procedure. Our aim was to compare, in the same dataset, both LA and RA volumes determined by an algorithm involving manual tracing to the corresponding volumes obtained by an algorithm with semiautomatic contour detection. Methods Maximal atrial volumes were measured in 88 patients using a multiplane interpolation method algorithm based on manual planimetry of 8 slices. These volumes were compared with volumes determined by the QLAB 8.1 software using semiautomatic border detection. Results Linear regression showed excellent correlation between volumes determined by manual and by semiautomatic software for both LA and RA (r2 = 0.90 and 0.89, respectively, P
