Combined assessment of left ventricular (LV) shape and function could provide new insights into the process of LV remodeling. Realtime 3D echocardiography (RT3DE) allows rapid and accurate semiautomated extraction of LV endocardial surfaces. Our aims were to quantify LV morphology both globally and regionally, using new ellipsoidal (E), spherical (S) and conical (C) shape indices, in a large population in order to define normal values. During systole the LV became less spherical and more conical, while E index remained unchanged. LV volume estimation was more affected by operator subjectivity than C and S indexes computation. These results constitute a reference for future comparisons with serial followup of patients during LV remodeling.

Abstract
Combined assessment of left ventricular (LV) shape and function could provide new insights into the process of LV remodeling. Realtime 3D echocardiography (RT3DE) allows rapid and accurate semiautomated extraction of LV endocardial surfaces. Our aims were to quantify LV morphology both globally and regionally, using new ellipsoidal (E), spherical (S) and conical (C) shape indices, in a large population in order to define normal values. During systole the LV became less spherical and more conical, while E index remained unchanged. LV volume estimation was more affected by operator subjectivity than C and S indexes computation. These results constitute a reference for future comparisons with serial followup of patients during LV remodeling.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
