Abstract

Objective: To evaluate the intra- and interobserver reproducibility of parameters used to determine cardiac morphometry and deformation using FetalHQ in Indian population.

Methodology: Two operators blinded to each other performed FetalHQ analysis independently on 35 normal fetuses of gestational age between 18 + 0 and 37 + 0 weeks and days. Intra- and interobserver correlation coefficient and limits of agreement were ascertained for parameters obtained from HQ analysis.

Results: Excellent reproducibility (ICC > 0.9) was observed for global morphometric parameters. Ejection fraction, stroke volume, stroke volume/kg demonstrated excellent reliability (ICC > 0.9), cardiac output, fractional area change showed a lower correlation (ICC < 0.8), and right and left ventricular global strain showed no correlation. Twenty-four segment sphericity index of left ventricle (LV) and right ventricle (RV) showed low to moderate correlation (LV-ICC 0.48-0.79; RV-ICC 0.43-0.82). Fractional shortening (FS) showed poor intraobserver reliability in RV.

Conclusion: FetalHQ provides reliable estimates of the global cardiac morphometry but not for global cardiac strain. Regional transverse contractility represented by FS has poor correlation in right ventricle, especially in the apical region, possibly due to moderator band. Nevertheless, it is a promising tool which requires technical advancements and validation to improve its accuracy and reliability.

在印度队列中使用胎儿心脏定量（fetalHQ）技术评估胎儿心脏。

目的评估在印度人群中使用 FetalHQ 确定心脏形态和变形的参数在观察者内部和观察者之间的可重复性：方法：由两名互不知情的操作者对 35 名胎龄介于 18+0 至 37+0 周和天数之间的正常胎儿独立进行 FetalHQ 分析。对 HQ 分析获得的参数确定了观察者内部和观察者之间的相关系数和一致性限值：结果：总体形态测量参数的重现性极佳（ICC > 0.9）。射血分数、每搏量、每搏量/千克显示出极佳的可靠性（ICC > 0.9），心输出量、分数面积变化显示出较低的相关性（ICC 结论：胎儿 HQ 可提供可靠的整体心脏形态估计值，但不能提供整体心脏应变估计值。FS所代表的区域横向收缩力与右心室的相关性较差，尤其是在心尖区，这可能是由于调节带造成的。尽管如此，这是一个很有前途的工具，需要技术进步和验证来提高其准确性和可靠性。

期刊介绍： The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography. The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents. JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
