Evaluation of Fetal Cardiac Function in Rheumatic Heart Disease (RHD)

Status Completed

Clinical Trial Summary

The goal of this study is to evaluate fetal myocardial performance in patients with heart diseases in comparison to normal pregnant patients.

Clinical Trial Description

Cardiac diseases affect 1-4% of pregnancies of industrialized countries,and the number of patients who develop cardiac problems during pregnancy is increasing.

Congenital heart diseases, ischemic heart and cardiac arrhythmias are the most dominant causes. In developing countries, rheumatic heart disease remains prevalent. Pregnancy induces haemodynamic changes with increased intravascular volume which may not only poses a risk of maternal death but also of serious morbidity such as heart failure, stroke and cardiac arrhythmia.

The fetus is not spared.Previous reports revealed a significant reduction in fetal growth rates associated with maternal heart disease.There is also association with preterm delivery and reduced birth weight. The presence of maternal cyanosis and a reduced cardiac output are the most significant predictors.

Accurate and reliable measurement of fetal cardiac function could be valuable for making the diagnosis and for fetal surveillanceThe most suitable parameters for assessing fetal cardiac function will mainly be determined by the cause of the dysfunction. Abnormal values of ejection fraction or cardiac output are usually found in the late stages of deterioration, and therefore more sensitive parameters have been proposed for earlier diagnosis and monitoring of fetal cardiac dysfunction. In most cases of cardiac dysfunction, diastolic parameters (such as DV or IRT) are the first to be altered, reflecting impaired relaxation and compliance due to a stiffer or less effective heart. Similarly, parameters reflecting longitudinal function (such as annular displacement or velocities) are typically affected in the early stages as compared to radial function (such as ejection fraction).

The goal of this study is to evaluate fetal myocardial performance in patients with heart diseases in comparison to normal pregnant patients. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
