Abstract
Antenatal diagnosis of structural CHD is now established in clinical practice in many countries. As a consequence, fetal cardiology has developed into a specialty on its own right. Extra-cardiac, chromosomal and genetic abnormalities are not uncommon associations, and therefore, a multidisciplinary approach is important when counselling families about diagnosis and prognosis of fetal CHD. Complex structural abnormalities can be accurately diagnosed in mid-gestation, and in many instances, this can be accomplished in the first and early second trimester of pregnancy. However, some forms of structural heart disease can progress as pregnancy advances and changes in the perinatal circulation can further modify the neonatal ultrasound findings. All these aspects need to be taken into account when informing parents about diagnosis of fetal heart disease, management plan for the pregnancy, surgical options for the neonate and child but also going into adulthood as well as a balanced account of current knowledge of likely short- to medium- to long-term outcome and long-life uncertainties that remain.
Prenatal diagnosis can improve mortality and morbidity of critical cardiac abnormalities. It prepares the family for postnatal events and helps with perinatal management plan by optimizing delivery, but in some instances, it also offers the family the option to continue with the pregnancy or not.
