Fetal Cardiac Remodeling in Singleton Pregnancies Conceived by Assisted Reproductive Technology (Biopsied and Non-Biopsied ICSI) Versus Those Normally Conceived

Recruiting

• Conditions: Fetal Cardiac Disorder

• Registration Number: NCT05172336
• Lead Sponsor: Wael Elbanna Clinic

Brief Summary

The study aims to assess the presence of fetal cardiac remodeling and dysfunction in singleton pregnancies conceived by assisted reproductive technology (Biopsied and Non-Biopsied ICSI) as compared with those conceived spontaneously (SC).

Detailed Description

For gynecologists, reaching a conclusion about fetal cardiac remodeling and dysfunction in singleton pregnancies conceived by assisted reproductive technology (Biopsied and Non-Biopsied ICSI) or conceived spontaneously (SC) that would influence the clinical decision and best practice. Besides enriching the clinical evidence in fetal cardiac remodeling and dysfunction.

For society, the conclusion and recommendation shall maximize the benefits and managing the benefits of the technique used. Moreover, providing more information for fetal cardiac remodeling and dysfunction.
