摘要
背景：对肺动脉瓣的准确评估可决定对右室流出道（RVOT）异常患者的临床治疗。与现有的正常参考值进行比较对于准确评估至关重要。该研究的目的是利用来自异质性儿科人群的 CT 测量数据，生成肺动脉瓣环和肺动脉管（ST）交界处的标准数据，并创建对临床实践有用的 Z 值：方法：纳入2014年4月至2021年2月期间在科罗拉多儿童医院接受心脏CT检查的无心脏病患者。测量了肺动脉瓣环和 ST 交界处的最小和最大直径（毫米）以及横截面积（平方毫米）。使用先前验证过的模型对测量结果进行归一化处理并计算 Z 值。将每个测量值与 BSA 相对照，并将 z 值分布作为参考线：分析了 367 名健康患者，他们的平均年龄为 8.8 岁（1-21 岁），56% 为男性，BSA 为 1.1 平方米（0.4-2.1 平方米）。海考克公式用于将数据显示为给定 BSA 的预测值以及与 BSA 有关的各测量方程内的数据。所有测量值的预测值和z-score边界以图表形式重新呈现：结论：CT 导出的肺动脉瓣环和 ST 交界处的标准数据来自一组不同类型的健康儿童。
Computed tomography-derived normative values and z-scores of the pulmonary valve annulus and sino-tubular junction in the pediatric population
Background
Accurate assessment of the pulmonary valve can dictate clinical management of patients with right ventricular outflow tract (RVOT) anomalies. Comparisons with available normal reference values are essential for accurate evaluation. The aim of the study was to generate normative data for the pulmonary valve annulus and sino-tubular (ST) junction using CT measurements derived from a heterogeneous pediatric population and create z-scores useful for clinical practice.
Methods
Patients without heart disease who underwent cardiac CT between April 2014 and February 2021 at Children's Hospital Colorado were included. Minimum and maximum diameter (mm) and cross-sectional area (mm2) for the pulmonary valve annulus and ST junction were measured. Previously validated models were used to normalize the measurements and calculate z-scores. Each measurement was plotted against BSA, and z-score distributions were used as reference lines.
Results
Three-hundred-sixty-seven healthy patients with a mean age of 8.8 years (1–21), 56% male, and BSA of 1.1 m2 (0.4–2.1) were analyzed. The Haycock formula was used to present data as predicted values for a given BSA and within equations relating each measurement to BSA. Predicted values and z-score boundaries for all measurements are graphically re-presented.
Conclusions
CT-derived normative data for the pulmonary valve annulus and ST junction is reported from a heterogenous cohort of healthy children.
期刊介绍：
The Journal of Cardiovascular Computed Tomography is a unique peer-review journal that integrates the entire international cardiovascular CT community including cardiologist and radiologists, from basic to clinical academic researchers, to private practitioners, engineers, allied professionals, industry, and trainees, all of whom are vital and interdependent members of our cardiovascular imaging community across the world. The goal of the journal is to advance the field of cardiovascular CT as the leading cardiovascular CT journal, attracting seminal work in the field with rapid and timely dissemination in electronic and print media.
