摘要目的既往研究报道使用经胸腔超声心动图(TTE)观察到主动脉根部尺寸具有中等遗传性。CT血管成像(CTA)可能会提供更准确的遗传性评价。本研究的主要目的是使用CTA评估主动脉根部的遗传性;次要目的是得到基于TTE的遗传性数据,并将其与基于CTA的数据相比较。方法在布达佩斯全球研究(BUDAPEST-GLOBAL)项目中,198对双胞胎[其中118对为单合子,80对为双合子,年龄为(56.1±
Abstract OBJECTIVE: Previous studies have reported a moderate hereditary size of the aortic root using thoracic echocardiography (TTE). CT angiography (CTA) may provide more accurate genetic evaluation. The primary objective of this study was to evaluate the hereditary nature of the aortic root using CTA. The secondary purpose was to obtain hereditary data based on TTE and compare it with CTA-based data. Methods In the Budapest Global Study (BUDAPEST-GLOBAL) project, 198 pairs of twins [118 were haplogroups and 80 were bizygotes with an age of (56.1 ±
