[Surgical cryoablation in a child with malignant ventricular tachycardia refractory to drugs and radiofrequency ablation].
A ten-months-old child with incessant monomorphic ventricular tachycardia is presented. Tachyarrhythmia is refractory to antiarrhythmic drugs and refractory to endocardial radiofrequency current ablation. Epicardial cryoablation of arrhythmogenic area without artificial circulation resulted in the abrupt termination of tachycardia. No tachyarrhythmias were inducible postoperatively. The reduction of ventricular rate by surgical cryoablation does produces resolution of the arrhythmia-induced cardiomyopathy.

[Study of colloidal osmotic pressure-total proteins--serum albumin relationship during and after extracorporeal circulation].
A postoperative increase in the pulmonary extravascular fluid volume (PEFV) and a disturbance of pulmonary gas exchange are regularly observed in patients undergoing cardiac surgery. These alterations, due to a reduction in the colloidal osmotic pressure (COP) increase the morbidity and mortality when crystalloid solutions are infused. This study was based on 90 patients infused with 1,500 cc of crystalloid solution without albumin. The COP, total proteins, albumin and globulin were determined in the plasma preoperatively, during bypass and immediately postoperatively, in order to define a formula allowing calculation of the COP from the plasma proteins to avoid reaching dangerously high figures. The authors concluded that there is a direct correlation between COP and total proteins (total proteins = 1.36 + 0.24 COP) and a potential curve with an adjustment point between COP and albumin (albumin = 0.23 COP0.93). Determination of the COP from globulins is not recommended. The authors elaborated two normograms for everyday clinical use. These formulae allow the calculation of COP in children, elderly subjects and patients in a critical condition, thereby avoiding dangerous levels of COP during infusion of crystalloid solutions.

[Anomalous origin of left coronary artery in pulmonary artery].
We report 2 infants aged 6 months and one year with an anomalous left coronary artery origin treated surgically at our centre with direct aortic reimplantation of the anomalous coronary. Evolution has been satisfactory, with a great improvement of ventricular function. The mitral incompetence and congestive heart failure have disappeared and myocardic perfusion electrocardiographic patterns were corrected. Because of the unfavorable natural course of the disease and the improvement in techniques of coronary revascularization in infants we recommend an early surgical treatment as soon as it be diagnosed. We consider that the most adequate surgical treatment is the direct aortic reimplantation of the anomalous coronary artery.

[The psychoneurological status of newborn infants with congenital heart disease before surgical intervention].
AIMS: This study was conducted to evaluate, from a psychological and neurological point of view, the situation of newborn infants (NI) suffering from congenital heart disease before they are treated surgically. At the same time, we aimed to compare this group of patients with another group of children who were considered to be healthy. PATIENTS AND METHODS: Patients psychological development was evaluated using developmental landmarks from the Observational Scale of Development (OSD), which provides a percentage of elements acquired in different areas. Behaviour was evaluated by the observational recording of particular patterns of behaviour. The neurological study was based on a detailed neonatal examination, performed by people from the Child Neurology Section at our hospital, and which took into account the different behaviours displayed by the NI: reactive, grasping, communicative and affective. RESULTS: Findings show significant differences both in the psychological and neurological variables studied. They show how, generally speaking, healthy infants score higher in the areas of development that were evaluated than children suffering from heart disease. Likewise, lower average scores were observed in heart disease patients who require an early intervention, as compared with those who will be submitted to surgery later on. From the neurological point of view, a number of significant differences were found in their muscular activity. CONCLUSIONS: This analysis, a groundbreaker in the study of infants suffering from heart disease before their surgical intervention, shows how newborn infants who have been submitted to surgery in the neonatal period present a significant degree of hypotonia, a certain frailness and retardation in their motor development.
