Fetal Cardiac Function Evaluation With aCMQ-Strain Fetal (STRAIN)

Fetal Cardiac Disorder

Cardiac function, Fetal, Strain

To assess whether the aCQM-Strain ultrasound method allows a good analysis of fetal cardiac function. Establish normality parameters and compare it with fetuses with risk factors of cardiac dysfunction.

National unicentric observational study of follow-up study of a cohort. It has been decided to conduct a study of consecutive cases, including all patients who meet the inclusion criteria during the time of the study. Until now, there has not been an easy and convenient method to determine fetal cardiac function. Recently a new Software (Automated Cardiac Motion Quantification aCMQ) has been developed, and it seems that allows an easier analysis of this one. This study aims to analyze fetal heart function with the Strain method in healthy patients and then compare it with fetuses with risk factors for cardiac dysfunction. Initially, healthy pregnant patients who agree to participate in the study will be cited, after signing the informed consent, in order to evaluate the normal fetal cardiac function and see how it is modified in the different weeks of gestation. To do this, a fetal echocardiography will be performed by the investigators at week 24, 28, 32 and 36 of pregnancy, using the aCMQ-Strain method. Once the investigators have established normality curves, fetuses with risk factors for cardiac dysfunction of women who agree to participate in the study will be analyzed. For this purpose, a fetal echocardiography at week 24, 28, 32 and 36 of gestation, using the aCMQ-Strain method will be performed. All tests will be carried out in the same study center and will be carried out by independent scouts.The data obtained in each test will be collected in an anonymized database for further study.
