[Prenatal diagnosis of tricuspid atresia]. / A tricuspidalis atresia praenatalis diagnosztikája.

Tricuspid atresia is the third most common cyanotic cardiac malformation, seen in 1 per cent of children with congenital heart disease. It occurs in 4-5 per cent of congenital heart defects diagnosed prenatally, this difference is a consequence of a high percentage of intrauterine death these severely ill fetuses. Initial surgical treatment is palliation, usually with aortopulmonary shunt. Definitive treatment is the Fontan operation, when the systemic venous return is connected directly to the pulmonary tree. Five-year survival for liveborn patients is 50, but for prenatally diagnosed fetuses only 20%. In Hungary there is only a few survivor. Authors have diagnosed 20 tricuspid atresias during a five-year period by fetal echocardiography. In two cases the postnatal findings were: normal tricuspid valves, univentricular atrio-ventricular connection and stenosis of the pulmonary artery, in one case dysplastic tricuspid valves, hypoplastic right ventricle and stenosis of the pulmonary artery. Authors summarise their experiences with prenatal echocardiography of tricuspid atresia and describe characteristic signs could be found by routine ultrasound screening of this severe cardiac malformation.

[Fetal myocardial calcification (report of 4 cases and review of the literature]. / Magzati myocardium calcificatio (négy eset ismertetése és irodalmi áttekintés).

(Report of four cases and review of the literature) Calcification of the myocardium is a rare condition. The cause may be dystrophic or metastatic. An autosomal recessive inherited idiopathic arterial calcification of infancy is more rare abnormality. A dystrophic calcification is the more common of the three and may occur in areas of necrosis, hemorrhage, or fibrosis of the myocardium. Metastatic calcification is associated with hyperparathyroidism, D hypervitaminosis or renal failure, usually accompanied by the deposit of calcium in other organs, particularly the lungs, stomach, kidneys, spleen and liver. Authors report four cases of myocardial calcification diagnosed in intrauterine life. They give a review of literature of fetal and neonatal myocardial calcification.
