Abstract

Background: Whether the in vitro fertilization (IVF) has an effect on the cardiac function of the fetus is very important to evaluate the safety of the technique. The aim of this paper is to establish normal reference range for the fetal right myocardial performance index (RMPI), and compare the reference range between IVF fetuses and spontaneous pregnancy (SP) fetuses by automatic measurement of the RMPI.

Methods: Three hundred seventy-one spontaneous singleton pregnancies (the control group) and 39 singleton pregnancies conceived by IVF (the experimental group) were enrolled into the current study. An automatic measurement system was used to acquire the RMPI. The cardiac function of the two groups was compared by t-test.

Results: There was no significant difference in normal reference range of RMPI between IVF fetuses and SP fetuses (RMPI 0.42 ± 0.05 vs 0.43 ± 0.05). No strong correlation was also noted between RMPI with gestational age and heart rate.

Conclusions: Normal reference ranges of RMPI of IVF fetuses and SP fetuses were established, and no significant difference between IVF fetuses and SP fetuses in RMPI was found. Thus, these findings may suggest that IVF has little impact on cardiac function of the fetus.

体外受精胎儿与自然妊娠胎儿右心肌功能指标评价的横断面研究。

背景:体外受精对胎儿心功能的影响是评价体外受精技术安全性的重要因素。本文的目的是建立胎儿右心肌功能指数(RMPI)的正常参考范围，并通过自动测量RMPI来比较IVF胎儿和自然妊娠(SP)胎儿的参考范围。方法:选取371例自然单胎妊娠(对照组)和39例体外受精单胎妊娠(实验组)为研究对象。采用自动测量系统获取RMPI。两组心功能比较采用t检验。结果:IVF胎与SP胎RMPI正常参考范围(RMPI 0.42±0.05 vs 0.43±0.05)差异无统计学意义。RMPI与胎龄和心率之间也没有很强的相关性。结论:建立了IVF胎和SP胎RMPI的正常参考范围，IVF胎和SP胎RMPI无明显差异。因此，这些发现可能表明体外受精对胎儿心功能的影响很小。

期刊介绍： Cardiovascular Ultrasound is an online journal, publishing peer-reviewed: original research; authoritative reviews; case reports on challenging and/or unusual diagnostic aspects; and expert opinions on new techniques and technologies. We are particularly interested in articles that include relevant images or video files, which provide an additional dimension to published articles and enhance understanding. As an open access journal, Cardiovascular Ultrasound ensures high visibility for authors in addition to providing an up-to-date and freely available resource for the community. The journal welcomes discussion, and provides a forum for publishing opinion and debate ranging from biology to engineering to clinical echocardiography, with both speed and versatility.
