Abstract

The anatomic value of the aortic root is important for aortic valve repair. This study was to determine the normal diameters of the aortic valve annulus (AVA) and sinus-tube joint (STJ) in the healthy adults of Chinese Han ethnic group, and to provide a morphological foundation for potential clinical application. Echocardiography was performed in 326 normal subjects, who were divided into 5 groups according to their age. The diameters of the AVA and STJ were measured in the parasternal long-axis view, and normalized to body surface area (BSA). They were averaged for each age group and for each gender. Differences were then determined between the normalized diameters for each age group and for both genders. Pearson's product-moment correlation coefficient was used to determine the differences between AVA and STJ diameters. It was also used to determine any positive or negative correlations between the above two variables and age, BSA, weight, and height. The diameters of the AVA and STJ of Han nationality patients increased with an increase in age, BSA, weight, and height. The correlation coefficient between AVA diameter and BSA was 0.4944 (P < 0.0001), between AVA diameter and age, 0.1138 (P < 0.05), between AVA diameter and we...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
