Prenatal Detection of Congenital Heart Defects: Study & Comparative Analysis of Existing Techniques

Congenital Heart defects (CHD) are one of the most common birth defects and is the foremost reason of the birth-defect associated deaths. A CHD is a structural or functional abnormality developed during pregnancy of the heart before birth. Over last few decades a lot of technological advancement took place for prenatal detection of CHD. We reviewed and analysed the performance of currently used techniques with the goal of determining a non-invasive, costeffective alternative for computer-aided diagnostic system. The distinguishing capabilities of different existing techniques are explored and compared. The outcome of that comparison is represented and discussed concretely. The comparison results confirm the prospects of Fetal Phonocardiography as a supporting tool which can be used for prenatal detection of CHD
