The Predictive Value of the CSA Index in the Prenatal Diagnosis of Aortic Coarctation in Ultrasound Examination Performed during the Second Trimester.

CSAi measurement is currently the most sensitive method for aortic coarctation detection. For the purpose of our study, this method was applied in diagnostics in the second trimester of pregnancy. This method is easy, reproducible and should be widely introduced into everyday echocardiographic diagnostics of coarctation to minimize the risk of error.
