Características y resultados del Registro español de válvula aórtica bicúspide en pediatría (REVAB) / Characteristics and outcomes of the Spanish registry for pediatric patients with bicuspid aortic valve (REVAB)

Introducción y objetivos: La válvula aórtica bicúspide (VAB) es la cardiopatía congénita más frecuente. El objetivo de este estudio es describir las características de los pacientes en edad pediátrica con VAB en un registro poblacional. Métodos: Los datos de los pacientes se obtuvieron del Registro español de válvula aórtica bicúspide (REVAB) en pediatría (menores de 18 años). Para el análisis de datos, se dividió a los pacientes en 2 grupos según sus características: pacientes con VAB solo y pacientes con VAB y cardiopatía congénita concomitantes. Resultados: Se analizó a un total de 1.681 pacientes de 33 hospitales. La mayoría (1.158, 69,6%) eran varones. La morfología de la válvula fue horizontal en el 63,4% (1.012), y puras (tipo 0 Sievers), el 28,4% (469). El 63,7% (1.060) tenían solo VAB y en el 23,4% (390) concurrían lesiones obstructivas del lado izquierdo. Del total, el 8,6% (145) precisó alguna intervención en la válvula aórtica. Conclusiones: Estos datos representan la primera descripción de base poblacional de la presentación clínica y los resultados en los pacientes del REVAB Pediátrico.(AU)

Introduction and objectives: Bicuspid aortic valve (BAV) disorder is the most common congenital heart disease. The aim of this study was to describe the characteristics of 0- to 18-year olds with BAV in a population-based registry. Methods: Data from all pediatric patients were obtained from the Spanish registry for pediatric patients with bicuspid aortic valve (REVAB) (< 18 years). For data analysis, patients with BAV were divided into 2 groups by their features: isolated BAV and BAV with associated congenital heart disease. Results: We included 1681 patients from 33 hospitals. Males accounted for 69.6% (n = 1158). Valve morphology was horizontal in 63.4% (n = 1012) and pure (Sievers type 0) in 28.4% (n=469). Isolated BAV was present in 63.7% (n=1060), and concomitant left-sided obstructive lesions in 23.4% (n=390). Interventions were required in 8.6% (n=145). Conclusion: These data represent the first large, population-based description of the clinical presentations and outcomes of patients enrolled in the Spanish registry for pediatric patients with bicuspid aortic valve.(AU)

Adolescents with bicuspid aortic valve: Which criteria should we use for aortic dilatation?

BACKGROUND: Criteria to define aortic dilatation in bicuspid aortic valve (BAV) patients are different for children and adults. The objective of this study was to find the best reference tool to define dilation of the aortic root (AR) and the ascending aorta (AA) in BAV adolescents with an adult body surface area (BSA). METHODS: Patients recruited were ≥10-years-old with a BSA ≥1.5 m2. Three measurements of the AR and AA were compared: z-score, the BSA-indexed value (BSA-IV) and the absolute value (AV), with thresholds in +2/+3, 21 mm/m2 and 40 mm, respectively. RESULTS: 231 subjects were collected from the Pediatric REVAB database, with a median age and BSA of 14-year-old and 1.67 m2. Significant differences were reported in the AA: 109 (47%) patients had a z-score ≥2 and 67 (29%) a Z ≥ 3, but only 9 (3%) a BSA-IV ≥21 mm/m2 (p < 0.01 and p < 0.01) and 2 (0.9%) an AV ≥40 mm (p = 0.22 and p = 0.08). CONCLUSION: Our results indicate that in the AA there are a significant number of patients in which it would be recommendable changing to BSA-IV when children are older than 10-year-old and BSA ≥1.5 m2. Regarding the AR, criteria for dilatation seems not to be influenced by the reference chosen.

Chronic chest pain after percutaneous atrial septal defect closure.

Percutaneous closure of atrial septal defect is recognised as a safe and effective procedure, however, in some patients complications may occur. Although chest pain has been sporadically reported, its exact aetiology has been poorly studied. Herein, a 14-year-old female with an atypical and long-lasting chest pain after percutaneous atrial septal defect closure is described.

Taquicardia paroxística supraventricular desde la perspectiva del transporte interhospitalario / Supraventricular tachycardia in children from the perspective of a specialised between-hospital transport team

OBJETIVO: Determinar la frecuencia de taquicardia paroxística supraventricular (TPSV) como motivo de traslado interhospitalario en la edad pediátrica, describir la forma de presentación clínica, evolución y tratamiento, y factores de riesgo de presentar compromiso hemodinámico y proponer un protocolo de manejo específico para el transporte. MÉTODO: Estudio retrospectivo observacional de los pacientes atendidos en el Sistema de Emergencias Médicas Pediátricas (SEM-P) del Hospital Vall d'Hebron entre enero 2005 y junio 2017. RESULTADOS: De un total de 7.348 traslados, 67 fueron pacientes con TPSV (0,9%). Edad mediana de 57 días de vida (2h a 18 años). Catorce pacientes (20,9%), presentaban signos de compromiso hemodinámico en el momento del diagnóstico. La edad ≤1 año fue el único factor de riesgo independiente para presentar compromiso hemodinámico al diagnóstico con un OR de 10,2 (IC 95%: 1,2-89,9; p: 0,004). La mayoría de pacientes revirtieron con las intervenciones del hospital emisor, exceptuando la intubación y la cardioversión eléctrica, realizadas más frecuentemente por el equipo de trasporte (ET). El tiempo mediano de estabilización fue de 35min (9-169), con un tiempo mediano de traslado de 30min (9-165). CONCLUSIONES: El transporte de pacientes pediátricos con TPSV es poco frecuente, pero puede requerir un manejo altamente especializado. La edad ≤1 año es el único factor de riesgo independiente para presentar compromiso hemodinámico. La coordinación entre el equipo del hospital emisor y el ET es de gran importancia para un buen resultado asistencial

AIMS: The aim of this study is to establish the incidence of supraventricular tachycardia (SVT) as a main reason for between-hospital transfer in children, as well as to describe the clinical presentation, prognosis and treatment, risk factors presenting with haemodynamic compromise, and to propose a specific management protocol for the transport. METHODS: A retrospective observational study was conducted on all patients with supraventricular tachycardia transferred by the Hospital Vall d'Hebron Sistema de Emergencias Médicas Pediátricas (SEM-P) between January 2005 and June 2017. RESULTS: During the study period, 67 (0.9%) patients (out of a total number of 7348 transfers) suffered from SVT. The median age was 57 days (2 hours-18 years old). There was clinical evidence of cardiogenic shock on admission in 14 (20.9%) patients. Age ≤ 1 year was the only independent risk factor associated with presenting with cardiogenic shock on admission, with an OR of 10.2 (95% CI: 1.2-89.9; P=.004). The majority of patients could be treated appropriately by the local hospital team, except for oral intubation and cardioversion that were performed mainly by the transport team on arrival at the local hospital. Median stabilisation time was 35minutes (9-169), and median total transport time was 30minutes (9-165). CONCLUSIONS: Only 0.9% of transport cases are due to SVT, but this can be highly demanding as patients can be critically ill. Age ≤ 1 year was the only independent risk factor associated with presenting with cardiogenic shock on admission. Coordination between the local and the transport teams is crucial for a good clinical outcome

Caracterización electrocardiográfica en una población de jóvenes estudiantes / Characterization of electrocardiographic findings in young students

INTRODUCCIÓN Y OBJETIVOS: El electrocardiograma (ECG) se ha propuesto como prueba de cribado de cardiopatías para jóvenes asintomáticos, pero hay controversia sobre su uso sistemático y no se dispone de datos sobre esta población en nuestro medio. El objetivo del presente estudio es determinar la prevalencia y la variedad de hallazgos electrocardiográficos en una población de estudiantes de secundaria. MÉTODOS: Estudio observacional descriptivo sobre un ECG en reposo de todos los estudiantes de 13 a 14 años de una comarca de la provincia de Girona entre 2009 y 2017. Los ECG se clasificaron en 3 grupos según los criterios de Corrado et al. modificados: ECG sin alteraciones, hallazgos electrocardiográficos que indiquen adaptación fisiológica y hallazgos electrocardiográficos patológicos. Se remitió a un hospital terciario solo a los estudiantes con alteraciones patológicas, a los que se realizaron pruebas complementarias según un protocolo preestablecido. RESULTADOS: Se obtuvieron 1.911 ECG, con una participación del 79% del total de alumnos. No presentaron alteraciones los ECG de 1.321 alumnos (69%); los de 554 alumnos (29%) tenían signos de adaptación fisiológica y los de 36 (2%), hallazgos patológicos (2%). Se llegó al diagnóstico de cardiopatía en 5 alumnos del grupo con hallazgos electrocardiográficos patológicos (14%). La prevalencia de cardiopatía en este grupo de jóvenes asintomáticos fue del 0,3%. CONCLUSIONES: En un tercio de la población estudiada se obtuvieron hallazgos electrocardiográficos, que mayoritariamente indicaban adaptación fisiológica. Se identificó cardiopatía en 1 de cada 7 alumnos con ECG patológico, aunque la prevalencia general de cardiopatía fue baja

INTRODUCTION AND OBJECTIVES: The resting 12-lead electrocardiogram (ECG) has been used in the evaluation of young asymptomatic individuals to detect pre-existing heart disease, but systematic ECG use is controversial and there are no data on this population in our environment. We aimed to determine the prevalence and spectrum of electrocardiographic findings in a population of secondary school students. METHODS: We conducted an observational, cross-sectional study of resting ECG findings in all 13 to 14-year-old secondary school students in a region of the province of Gerona between 2009 and 2017. ECG findings were classified into 3 groups according to the modified criteria of Corrado et al.: normal ECG findings, ECG findings suggestive of adaptive changes, and pathologic findings. Students with pathologic ECG findings were referred to a tertiary hospital, and complementary tests were performed according to a pre-established protocol. RESULTS: A total of 1911 ECGs were obtained, with a participation rate of 79% of all high school students. In all, 1321 students (69%) had a normal ECG, 554 (29%) showed ECG findings suggestive of adaptive changes, and 36 (2%) had pathologic ECG findings. Among the group with pathologic findings, 5 (14%) had cardiovascular disease. The prevalence of heart disease in this group of asymptomatic secondary school students was 0.3%. CONCLUSIONS: One third of the students had ECG findings that were mostly suggestive of physiological adaptation. One seventh of the students with pathologic ECG findings had pre-existing heart disease, although the overall prevalence of pre-existing heart disease was low
