NCT02190422

Brief Summary

Assisted reproductive technology (ART) has extensively allowed pregnancy for infertile couples. However, the long-term effect of ART exposure on cardiovascular development and potential association with ART procedure and parental factors is confused. The aim is to shed more light on the pattern and extent of cardiovascular developmental alteration among ART children and its association with potential confounders.

Outcome Measures

Primary Outcomes (1)

  • cardiovascular geometric morphology between controls and ART children

    Left ventricular end-diastolic diameters (LVDD) and end-systolic diameters (LVSD) will be measured by M-mode echocardiography at the para-sternal long-axis views. LV end-diastolic volume (LVEDV) and end-systolic volume(LVESV) will be calculated by 2D echocardiography from the apical four-chamber view using the modified Simpson's rule. Aorta diameters (AOD) and left atrial diameters (LAD) will be measured by 2D echocardiography at the para-sternal long-axis views. Left and right coronary artery will be measured by 2D echocardiography at the short-axis views. The interventricular septum thickness (IVST) and the left ventricular posterior wall thickness (LVPWT) will be measured by M mode from a para-sternal long-axis view. Left ventricular relative wall thickness (LVRWT) will be calculated the following equation: (IVST+PWT)/ LVDD.

    participants will be followed for the duration of hospital stay, an expected average of 3 weeks

Secondary Outcomes (1)

  • cardiac function between controls and ART children

    participants will be followed for the duration of hospital stay, an expected average of 3 weeks

Study Population

ART group will be ART children conceived in Clinical Centre of Reproductive Medicine and born in Maternal-Fetal Medicine Unit (MFMU). The controls will be the spontaneous conception children born in the MFMU during the same period as ART group for prenatal screening and subsequent delivery.

You may qualify if:

  • the capability of complete examination of transthoracic echocardiography
  • the absence of complex cardiac malformations and systematic diseases.

You may not qualify if:

  • the presence of a history of systemic diseases, frequent arrhythmias, and critical acquired heart diseases,
  • the presence of the background of familiar cardiomyopathy in their family,
  • limited acquisitions of echocardiographic imaging
  • poor image quality for assessment.
