BACKGROUND Children with multisystem involvement including congenital heart defect (CHD) are a very salient problem. The purpose of this study was to evaluate the incidence of CHD associated with malformations of other systems and to assess the modalities of treatment and perioperative mortality among patients referred to the department of pediatric cardiac(More)
Measurement of the heart rate variability enables to assess the activity of the autonomous nervous system. The aim of the study was to evaluate the possible relationship between clinical status, serum sodium (Na), potassium (K), calcium (Ca), magnesium concentrations and HRV in children with mitral valve prolapse. The study group consisted of 151 children(More)
BACKGROUND Left ventricular (LV) dysfunction has been described in adults with secundum atrial septal defect (ASD II) and heart failure (CHF). This anomaly has been rarely regarded as a cause of CHF in pediatric patients with ASD II. AIM To assess LV systolic and diastolic function in patients with ASD II before and after cardiosurgery as well as to(More)
The aim of this study was to determine plasma concentration of magnesium, potassium, calcium and sodium in children with mitral valve prolapse (MVP) and to establish the relation between electrolyte abnormalities and ventricular arrhythmias (VA). The study group consists of the 113 children with MVP (age +/- SD: 10.7 +/- 4.3 years). The 101 healthy children(More)
We aimed prospectively to determine the incidence of ventricular arrhythmias and ventricular late potentials in children with mitral valvar prolapse, and to assess whether signal-averaged electrocardiography could identify which such children were at high risk of developing ventricular tachycardia. In all, we examined 151 children with mitral valvar(More)
A 4-year-old girl with a 1-month history of cardiac insufficiency, fatigue, tachycardia, heart murmur, hepatomegaly, and intermittent fever was admitted to our clinic. Until then, the child had been developing normally. Family history was negative. Physical examination revealed fatigue, fever, pale skin, tachypnoea (35/min) with vesicular rales, tachycardia(More)
A case of a 2-day-old newborn with congenital heart disease, pulmonary atresia and ventricular septal defect is described. The Blalock-Taussig shunt was created 6 days after birth. After the procedure, the newborn developed symptoms of increased pulmonary blood flow and respiratory distress. We decided to close one of the major aortopulmonary collateral(More)
We report the case of fetal goiter which occurred in two consecutive pregnancies in the same patients. The first one, due to too late diagnosis and no intrauterine treatment, contributed to the immediate postnatal death of the newborn; the second one was properly diagnosed at 19 weeks and then effectively treated prenatally which allowed to avoid the fatal(More)
OBJECTIVE Depressed cardiac function after aortoventriculoplasty is well known during the postoperative period. Little data exist concerning the long-term follow-up. The aim of this study is to determine whether septal incision has any permanent effect on the left ventricle function. METHODS From 1988 to 2002, 45 patients received aortic mechanical(More)
