Annulo-aortic ectasia can be an isolated condition or can occur as part of a generalised connective tissue disorder, e.g. Two-dimensional measurements of the AR were made at end-diastole in parasternal long-axis views at 4 levels: (1) annulus (defined echocardiographically as the hinge points of the aortic cusps), (2) sinuses of Valsalva, (3) sinotubular junction, and (4) proximal ascending aorta. There are significant differences in aortic dimensions according to sex, age, and race. The specific manner in which these measurements are obtained is of obvious importance. Left Atrial Volume Index (LAVI) has been found to correlate with mortality from cardiovascular disease and may be measured at the end-ventricular systole, when the LA is at its maxim size. This is because BSA was previously found to have a greater association with thoracic aortic diameter than BMI does (6,7), and BSA was the body size variable that entered into selection models most frequently.
