3D Echocardiographic Assesment of Left Ventricle Size and Function with Automated Adaptive Software in Patients with Right Heart Dominant

Abstract

Introduction : Echocardiography is a fundamental tool for assessing cardiac chamber size and function, with evolving technologies like real-time three-dimensional echocardiography (3DE) and automated quantification software offering new possibilities. This study aims to validate left ventricular (LV) measurements obtained through automated quantification software against manual 3DE and 2D measurements, explore the relationship between these measurement techniques, and compare their reproducibility and analysis time.

Methods : A total of 60 patients with uncorrected severe mitral stenosis (MS) and atrial septal defect (ASD) underwent echocardiography. Automated and manual 3DE measurements were compared, with subgroup analysis for software performance. Analysis times were also assessed.

Results : The automated quantification software did not work in 16 patients, with notable differences in tricuspid regurgitation parameters. Automated 3DE measurements yielded larger LV volumes than manual 3DE measurements, while LV ejection fraction (LVEF) measurements were smaller. Good correlations were observed, but agreement analysis revealed significant differences between the two methods. The use of automated software significantly reduced analysis time.

Conclusions : Automated quantification software can effectively measure LV parameters in patients with MS and ASD, significantly reducing analysis time. However, manual methods may still be necessary in cases with structural changes or unique anatomical conditions, emphasizing the importance of selecting the appropriate measurement technique for specific patient populations.
