Echocardiographic two-dimensional view of the pulmonary valve in infants: the high transsternal view.

Neonates and small infants have unique characteristics that make it possible to obtain echocardiographic views that are inaccessible in older patients. A high transsternal approach through the cartilaginous sternum and the thymus gland allows visualisation of a short-axis view of the pulmonary valve. This view should be included as part of routine protocols for echocardiographic examinations performed in this age group.

Pulmonary vasodilator therapy and early postoperative outcome after modified Fontan operation.

Although mortality is low after the modified Fontan procedure, there is a significant percentage of patients with prolonged postoperative recovery. The objective of this study is to evaluate the usefulness of postoperative administration of oral sildenafil and inhaled nitric oxide on early postoperative outcome. A prospective interventional and comparison study with a historical cohort was conducted. Between January, 2010 and March, 2013, 16 patients received oral sildenafil during immediate modified Fontan postoperative period. Inhaled nitric oxide was also administered if the patient was kept intubated 12 hours after surgery. Early postoperative outcome was compared with a historical cohort of 32 patients on whom the modified Fontan procedure was performed between March, 2000 and December, 2009. Postoperative administration of sildenafil and nitric oxide had no influence on early postoperative outcome after the modified Fontan procedure in terms of duration of pleural effusions, mechanical ventilation time, length of stay in the ICU, and length of hospital stay.

Operación de Fontan. Estudio de los factores hemodinámicos asociados a la evolución postoperatoria / Fontan operation. Hemodynamic factors associated with postoperative outcomes

Introducción y objetivos. Los pacientes con corazón univentricular son sometidos a una serie de intervenciones paliativas que culminan en la operación de Fontan. El objetivo de este trabajo es revisar las características clínicas y hemodinámicas de un grupo de pacientes con fisiología univentricular paliados previamente con operación de Glenn bidireccional e identificar los factores de riesgo que influyen en la evolución postoperatoria de la cirugía de Fontan. Métodos. Estudio retrospectivo de 32 pacientes sometidos a cirugía de Fontan entre marzo de 2000 y diciembre de 2009. Se revisaron las características clínicas, los datos derivados del cateterismo, el tipo de cirugía y los tiempos quirúrgicos y se buscó su relación con la evolución postoperatoria. Resultados. La mortalidad hospitalaria fue del 3%. Tras una mediana [intervalo intercuartílico] de seguimiento de 44 meses [32-79], la supervivencia es del 90%. La presión media en arteria pulmonar medida en el cateterismo se relacionó con la mortalidad tardía. De las demás variables estudiadas, las que mejor se relacionaron con la evolución postoperatoria fueron los índices de Nakata y McGoon y el tiempo de circulación extracorpórea. En el 42% de los pacientes se realizó cateterismo intervencionista previo a la operación de Fontan. Conclusiones. Realizamos la operación de Fontan con muy baja mortalidad hospitalaria. El cateterismo previo a la operación de Fontan permite seleccionar a los pacientes de alto riesgo para la cirugía así como realizar procedimientos intervencionistas que podrían mejorar la evolución postoperatoria (AU)

Introduction and objectives. The Fontan operation is usually the final palliative procedure in patients with univentricular heart. The objectives of this study were, firstly, to describe the clinical and haemodynamic characteristics of a group of patients with univentricular physiology who had previously been palliated with a bidirectional Glenn procedure and, secondly, to identify risk factors that can influence postoperative outcomes after the Fontan operation. Methods. Retrospective study with 32 patients who underwent a Fontan operation between March 2000 and December 2009. Clinical characteristics, catheterization data, type and duration of surgery were revised and analyzed as predictors of postoperative outcome. Results. Hospital mortality was 3%. After a median follow-up of 44 months (interquartile range, 32-79), survival was 90%. Preoperative mean pulmonary arterial pressure (measured during catheterization) was correlated with late mortality. Of the remaining variables analyzed, the Nakata and McGoon indices, and duration of cardiopulmonary bypass showed the highest correlations with postoperative outcomes. Interventional catheterization before the Fontan operation was performed in 42% of patients. Conclusions. Hospital mortality after the Fontan operation was very low. The performance of a haemodynamic study before the Fontan operation made it possible to select high-risk patients for surgery as well as permitting the performance of interventional procedures that could improve postoperative outcome in these patients (AU)

INTRODUCTION AND OBJECTIVES: The Fontan operation is usually the final palliative procedure in patients with univentricular heart.

Imported malaria in children: a comparative study between recent immigrants and immigrant travelers (VFRs).

BACKGROUND: In Europe, imported malarial cases occur in returning travelers and immigrants mostly from African countries. There have been an increasing number of cases in the past years in Spain. METHODS: An analysis of all cases of malaria who attended at the Hospital of Mostoles in the Southwest of Madrid from 1995 to 2007 was performed. Clinical, epidemiological, laboratory, and parasitological findings were analyzed and compared between immigrants coming from endemic countries (recent immigrants) and children who traveled to endemic areas to visit friends and relatives (VFRs). RESULTS: Sixty cases of imported malaria were detected. Most of the cases (59 of 60) were acquired in sub-Saharan Africa. The most common species was Plasmodium falciparum (43 of 60). Microscopic examination was positive in 95%, and the polymerase chain reaction (PCR) for Plasmodium achieved additional diagnosis in seven cases. Fourteen cases were VFRs; none of them used appropriate malaria chemoprophylaxis. Fever and thrombocytopenia were significantly more common among VFRs. They also had significantly higher parasite density. Twelve cases were asymptomatic at the time of diagnosis; all of them were recent immigrants. CONCLUSIONS: VFRs account for a significant number of childhood malarial cases. These patients had not taken malaria chemoprophylaxis and malarial cases were more severe. VFR children are a high-risk group, and pretravel advice should underline the risk for malaria. Recent immigrants can be asymptomatic and parasitemias are lower. Therefore, a high index of suspicion is necessary, and PCR for Plasmodium should be performed in case of negative thick smears.
