Mid-term morbidity and mortality of patients after arterial switch operation in infancy for transposition of the great arteries.

Introduction And Objectives: The arterial switch operation is currently the preferred surgical approach for complete transposition of the great arteries. We sought to determine the mid-term results of this intervention.

Methods: A single-institution retrospective review of clinical records of all consecutive patients who underwent the arterial switch surgery between 1985 and 2010.

[Prognostic evaluation of arterial switch in the transposition of great arteries].

Introduction And Objectives: The arterial switch is the procedure of choice for transposition of great arteries, with or without ventricular septal defect. The aim of this study was to identify risk factors for hospital mortality.

Methods: The study included 121 children between January 1994 and June 2008.

[Postsurgical pseudoaneurysm of the right ventricular outflow tract].

Cardiac pseudoaneurysm, a sealed rupture of the heart, is potentially fatal if not repaired surgically. The incidence in children is low, and it has been described in connection with surgery involving the right ventricular outflow tract. We describe a case diagnosed 20 months after complete repair of Tetralogy of Fallot with a single 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.

[Aortopulmonary window: clinical assessment and surgical results].

Introduction And Objectives: Aortopulmonary septal defect is an uncommon congenital cardiac anomaly. To date, approximately 300 cases have been reported. We present our experience, emphasizing the importance of early correction to avoid irreversible pulmonary hypertension.

[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.

[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.

[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.
