ReviewThe impact of prenatal diagnosis of congenital heart disease on pediatric cardiology and cardiac surgery.
Since the early 1980s prenatal diagnosis of congenital heart disease (CHD) has progressively impacted on the practice of pediatric cardiology and cardiac surgery. Fetal cardiology today raises special needs in screening programs, training of the involved staff, and allocations of services. Due to the increased detection rate and to the substantial number of terminations, the reduced incidence of CHD at birth can affect the workload of centers of pediatric cardiology and surgery. ⋯ Prenatal diagnosis allows counselling of families which are better prepared for the foreseeable management and outcome of the fetus. These benefits can reduce the risks of litigation for missed ultrasound diagnosis. As increased costs can be expected in institutions dealing with a large number of fetal CHD, the administrators of these institutions should receive protected funds, proportional to their needs.

ReviewPatent foramen ovale and cryptogenic stroke. A critical review.
The underlying causes of ischemic stroke in young patients are often difficult to find, despite systematic investigations concerning heart, coagulation system or any other type of vascular disease, thus the definition of 'cryptogenic'. In patients with cryptogenic stroke, the prevalence of a patent foramen ovale is about 45%, versus 25% of the general healthy population, leading to many speculations about a potential role of intracardiac right-to-left shunts in determining ischemic cerebral disease. Since a possible mechanism has been thought to be paradoxical embolism, percutaneous closure of the foramen ovale is currently discussed, at least until the appearance of data from the ongoing randomized trials. ⋯ Professional divers may benefit from the procedure as well, whereas migraine is still not considered an indication. In the pediatric population, closure of the patent foramen ovale seems to be safe and effective to prevent recurrent stroke. As the complication rate for device implantation decreases, the threshold for percutaneous closure is likely to decline.
