Short presentation about congenital heart diseases, fetal circulation, transitorial, neonatal, normal pediatric circulation. Symptoms of congenital heart diseases are persistent unexplained central cyanosis or desaturation – even if mild initially, desaturation or cyanosis that does not improve with oxygen or ventilation, a significant persistent difference in upper and lower limb saturations, congestive heart failure (newborn, infants),cyanosis, cardiomegaly, poor growth, arrythmias, murmurs, respiratory syndrome, bronchitis. This short presentation also includes diagnosis and treatment of congenital heart diseases.

Cardiac tamponade is a clinical syndrome caused by the accumulation of fluid or gas in the pericardial space, resulting in reduced ventricular filling and therefore decreased cardiac output (Figure 1). The condition is a medical emergency with resultant cardiogenic shock and death if not treated immediately. The presented case report describes a 63-year-old oncological patient who developed cardiac tamponade with the need of pericardiocentesis.

The incidence of urolithiasis is 0.1-0.5-1%.The prevalence of of urolithiasis nearby 4%, in children 5,8/100, 000 children/year, M: F ratio 2:1. Recurency only once in a lifetime in about 50%. Different urolithiasis composition and metabolic changes in 50-75% pts. Etiology is unknown. There are multifactorial nature, endogenous, exogenous causes, intranefrotic, extranefrotic creation, metabolic disorders, local factors in the urinary tract as a small diuresis, immobilization, genetic factors-polygenic effect (RTAs and cystinuria), familial clustering, the impact of welfare (climate, social factors, physical activity, occupation, gender, age, ethnic and genetic influences, food, water, pregnancy, lactation, etc.).

Virtual scenarios for cardiac surgery are developed and improved within projects’ activities of the authors and their primary aim is to foster development of critical thinking in students of medical and healthcare disciplines. Individual patient simulations contribute to the case-based learning approach that is learning style close to the needs of practice. Furthermore, we expect their better preparation for bedside teaching.

The case report describes the hospitalization of a 26 year old male with M. Barlow. The mitral valvuloplasty was performed. However, the peroperative ultrasonographic finding documented prolapse of the anterior cusp of the mitral valve into the outflow tract of left ventricle. The surgery was supplemented with a suture of the A2-PA segments of mitral valve. The subsequent finding was satisfactory. No more serious postoperative complications were noted. The patient was admitted to outpatient care on the eighth postoperative day.
