Percutaneous Retrieval of a Vegetation in a Pediatric Patient with Patent Ductus Arteriosus: A New Technique to Avoid Thoracotomy.

Infective endocarditis in the pediatric population is a rare condition that may or may not be associated with a congenital heart disease. Current treatment modalities are based on long-term antibiotic therapy and surgical resection as the first option for cases of persistent vegetation. We present a case of successful percutaneous retrieval of a vegetation in a patent ductus arteriosus, that extended to the pulmonary artery trunk in a pediatric patient.

Closure of small fenestrations without optimal rims with a PDA coil far from primary atrial septal defects: a new approach.

An ostium secundum atrial septal defect (ASD) is a CHD that can be treated percutaneously since 1974, mostly cases with only one main defect. In cases with fenestrations close to the main defect, a single occluder can be used for treatment because the discs extend beyond the waist of the device. In some cases where the defects are far from each other, they may require either more than one device or surgical closure.

[Cardiovascular manifestations in pediatric multisystem inflammatory syndrome associated with COVID-19 in a tertiary care pediatric center in Mexico City].

Objective: The objective is to expose the cardiovascular alterations in patients diagnosed with pediatric inflammatory multisystem syndrome (PIMS) associated with COVID-19 during the SARS-CoV-2 pandemic, in order to understand the disease, its evolution, and optimal management upon diagnosis.

Method: Retrospective, observational, cross-sectional analytical study of patients diagnosed with PIMS according to the criteria of the World Health Organization at the National Institute of Pediatrics, from March 2020 to December 2021.

Results: During the study period, 77 patients with PIMS were diagnosed.

Intravenous prostaglandin E1 (alprostadil) bolus in ductus arteriosus-dependent CHD: valid or absolutely contraindicated?

The use of prostaglandin E1 is well documented in ductus arteriosus-dependent CHD or in neonatal pulmonary pathologies that cause severe pulmonary hypertension. The intravenous infusion is well established in loading infusion and maintenance with an onset of action of 30 minutes until 2 hours or even more. Our aim is to report three patients with pulmonary atresia that presented hypercyanotic spell due to a ductal spasm during cardiac catheterisation in whom the administration of a bolus of alprostadil reversed the spasm and increased pulmonary flow, immediately stabilising the condition of the patients allowing subsequent successful stent placement with no serious complications or sequelae after the administration of the bolus.

[Validation of the instrument "Infant Malnutrition and Feeding Checklist for Congenital Heart Disease", a tool to identify risk of malnutrition and feeding difficulties in infants with congenital heart disease].

Introduction: currently, various tools have been designed to timely detect the risk of malnutrition in hospitalized children. In those with a diagnosis of congenital heart disease (CHD), there is only one tool developed in Canada: Infant Malnutrition and Feeding Checklist for Congenital Heart Disease (IMFC:CHD), which was designed in English. Objective: to evaluate the validity and reliability of the Spanish adaptation of the IMFC:CHD tool in infants with CHD.

[Presentation and management of congenital heart disease in the first year of age].

Congenital heart disease (CHD) is defined as a structural abnormality of the heart or large intrathoracic vessels. They constitute the most frequent congenital malformation at birth. At least one third of patients require some type of intervention before the year of age.

Pilot phase experience of the International Quality Improvement Collaborative catheterization registry.

Objectives: To describe the development of a quality collaborative for congenital cardiac catheterization centers in low and middle-income countries (LMICs) including pilot study data and a novel procedural efficacy measure.

Background: Absence of congenital cardiac catheterization registries in LMICs led to the development of the International Quality Improvement Collaborative Congenital Heart Disease Catheterization Registry (IQIC-CHDCR). As a foundation for this initiative, the IQIC is a collaboration of pediatric cardiac surgical programs from LMICs.

From an innocent heart murmur to pulmonary arterial hypertension.

Background: The detection of congenital heart disease in newborns, based on a heart murmur or cyanosis is not effective. Critical congenital heart diseases, such as truncus arteriosus (TA), cause most of neonatal deaths due to congenital malformations. The screening for pulse oximetry in newborns detects up to 70% of these heart diseases.

Outcomes of the Non-fenestrated Fontan Procedure at High Altitude.

Background: Although high altitude has been considered a risk factor for the Fontan operation, and an indication for fenestration, there is a paucity of data to support its routine use. Fenestration, with its necessary right to left induced shunt, together with the lower partial pressure of oxygen found with progressive altitude, can significantly decrease hemoglobin oxygen saturation, and therefore, it would be desirable to avoid it.

Objective: To analyze immediate and medium-term results of the non-fenestrated, extracardiac, Fontan procedure at high altitude.
