Normal aortic root dimensions were established from studies from Western countries. As the body size is significantly associated with the aortic root dimensions, Thai populations may have smaller aortic root diameters.
To elucidate the aortic root dimensions using transesophageal echocardiography (TEE) in adult patients undergoing cardiac surgery.
A retrospective cohort study including 150 patients aged >18 years undergoing cardiac surgery.
Aortic root dimensions (annulus, sinus of Valsalva, sinotubular junction (STJ), and proximal ascending aorta) were measured using two-dimensional TEE. Patients with aortic-root related pathology were excluded.
Men constituted 60% of the study population; the mean age was 61.9 ± 12.6 years, and mean body surface area (BSA) was 1.7 ± 0.2 m. The absolute dimensions for the annulus, sinus of Valsalva, STJ, and proximal ascending aorta were 22.3 ± 3.4, 32.6 ± 3.9, 26.4 ± 3.3, and 29.3 ± 3.1 mm, respectively, in men (12.9 ± 1.6, 18.8 ± 2.6, 15.2 ± 2.1, and 17.9 ± 2.7 mm, respectively, after adjusting for BSA) and 20.3 ± 2.2, 29.8 ± 3.6, 23.8 ± 2.6, and 27.1 ± 3.1 mm, respectively, in women (13.5 ± 2.0, 19.8 ± 2.3, 15.8 ± 2.5, and 17.0 ± 2.1 mm, respectively, after adjusting for BSA). The absolute aortic root diameters were significantly greater in men at all levels (P < 0.001). The BSA-adjusted diameters were similar for both sexes at the annulus (P = 0.076) and STJ (P = 0.076), except for the sinus of Valsalva (P = 0.010) and proximal ascending aorta (P = 0.006).
This study reports reference values of aortic root dimensions by TEE. The body size should be considered when comparing the aortic root dimensions of Thai populations with the standard normal values.
正常主动脉根部尺寸是基于西方国家的研究得出的。由于身体大小与主动脉根部尺寸密切相关，泰国人群的主动脉根部直径可能较小。
使用经食管超声心动图（TEE）阐明成年心脏手术患者的主动脉根部尺寸。
这是一项包括 150 名年龄>18 岁接受心脏手术的患者的回顾性队列研究。
使用二维 TEE 测量主动脉根部尺寸（瓣环、主动脉窦、窦管交界和升主动脉近端）。排除与主动脉根部相关疾病的患者。
男性占研究人群的 60%；平均年龄为 61.9 ± 12.6 岁，平均体表面积（BSA）为 1.7 ± 0.2 m。男性瓣环、主动脉窦、窦管交界和升主动脉近端的绝对尺寸分别为 22.3 ± 3.4、32.6 ± 3.9、26.4 ± 3.3 和 29.3 ± 3.1 mm（BSA 校正后分别为 12.9 ± 1.6、18.8 ± 2.6、15.2 ± 2.1 和 17.9 ± 2.7 mm），女性分别为 20.3 ± 2.2、29.8 ± 3.6、23.8 ± 2.6 和 27.1 ± 3.1 mm（BSA 校正后分别为 13.5 ± 2.0、19.8 ± 2.3、15.8 ± 2.5 和 17.0 ± 2.1 mm）。在所有水平上，男性的主动脉根部直径绝对值均显著大于女性（P<0.001）。除主动脉窦（P=0.010）和升主动脉近端（P=0.006）外，男女瓣环（P=0.076）和窦管交界（P=0.076）的 BSA 校正直径相似。
本研究报告了 TEE 主动脉根部尺寸的参考值。在将泰国人群的主动脉根部尺寸与标准正常值进行比较时，应考虑身体大小。
