Abstract

INTRODUCTION

Dilatation of the ascending aorta is a common finding in Tetralogy of fallot (TOF). We sought to provide aortic dimensions in children and adolescents after corrected TOF obtained by contrast-enhanced cardiac-magnetic-resonance angiography (CE-CMRA) that could serve as reference values.

MATERIALS AND METHODS

We enrolled 101 children and adolescents (56 male) with a median age of 10.9 years. All patients underwent CE-CMRA imaging using a 3-dimensional spoiled gradient-echo-sequence. Aortic diameters were measured at the level of the aortic valve (AV), aortic sinus (AS), sino-tubular junction (STJ) and the ascending aorta (AA) and compared with normal values obtained from literature. Sex-specific aortic dimensions are given as percentile curves as well as z scores. Furthermore CMR volumetric and functional parameters as well as clinical and anamnestic data were analyzed to identify parameters that are associated with aortic dilatation.

RESULTS

Diameters for aortic size for males were 3.6 + 16.6BSA(0.5) at the AV level, 7.0 + 19.5BSA(0.5) at the AS level, 7.0 + 14.4BSA(0.5) at the STJ level and 7.3 + 15.5BSA(0.5) at the AA level. Diameters for females were 5.8 + 14.1BSA(0.5) at the AV level, 7.2 + 17.6BSA(0.5) at the AS level, 5.2 + 15.4BSA(0.5) at the STJ level and 2.0 + 17.8BSA(0.5) at the AA level. All diameters in TOF patients were larger compared with normal values. The postoperative interval and age at examination were the only parameters associated with aortic size at all measured levels.

CONCLUSION

We provide CE-CMRA data of aortic dimensions in children and adolescents after correction of TOF. Our data might be useful for an estimation of the "normal" aortic size in this patient cohort and can serve as a basis for future longitudinal studies adding prognostic data.

摘要

引言

升主动脉扩张是法洛四联症(TOF)的常见表现。我们试图通过对比增强心脏磁共振血管造影(CE-CMRA)获取矫正型TOF患儿及青少年的主动脉尺寸,作为参考值。

材料与方法

我们纳入了101例儿童及青少年(56例男性),中位年龄为10.9岁。所有患者均采用三维扰相梯度回波序列进行CE-CMRA成像。在主动脉瓣(AV)、主动脉窦(AS)、窦管交界(STJ)及升主动脉(AA)水平测量主动脉直径,并与文献中的正常值进行比较。按性别给出主动脉尺寸的百分位数曲线及z值。此外,分析CMR容积和功能参数以及临床和既往病史数据,以确定与主动脉扩张相关的参数。

结果

男性患者在AV水平的主动脉尺寸直径为3.6 + 16.6×体表面积(BSA)^(0.5),AS水平为7.0 + 19.5×体表面积(BSA)^(0.5),STJ水平为7.0 + 14.4×体表面积(BSA)^(0.5),AA水平为7.3 + 15.5×体表面积(BSA)^(0.5)。女性患者在AV水平的直径为5.8 + 14.1×体表面积(BSA)^(0.5),AS水平为7.2 + 17.6×体表面积(BSA)^(0.5),STJ水平为5.2 + 15.4×体表面积(BSA)^(通过对比增强心脏磁共振血管造影(CE-CMRA)获取矫正型TOF患儿及青少年的主动脉尺寸,作为参考值。

结论

我们提供了矫正型TOF患儿及青少年主动脉尺寸的CE-CMRA数据。我们的数据可能有助于估计该患者群体的“正常”主动脉尺寸,并可为未来增加预后数据的纵向研究提供基础。

注

原文中女性患者AA水平直径“2.0 + 17.8*BSA(0.5)”可能有误,已按原样翻译。
