Acute myocarditis is an inflammatory disease of the myocardium, and it can present as severe heart failure in children. Differential diagnosis with genetic cardiomyopathy can be difficult. The objective of this study is to identify patterns of clinical presentation and to assess invasive and non-invasive measures to differentiate patients with acute myocarditis from patients with dilated genetic cardiomyopathy. We performed a retrospective descriptive study of all paediatric patients (0-16 years old) that presented with new-onset heart failure with left ventricle ejection fraction < 35% in whom we performed an endomyocardial biopsy (EMB) during the period from April 2007 to December 2020. The patients were classified into two groups: Group 1 included 18 patients with myocarditis. Group 2 included 9 patients with genetic cardiomyopathy. Findings favouring a diagnosis of myocarditis included a fulminant or acute presentation (77.8% vs 33.3%, p = 0.01), higher degree of cardiac enzyme elevation (p = 0.011), lower left ventricular dimension z-score (2.2 vs 5.4, p = 0.03) increase of ventricular wall thickness (88.8% vs 33.3%, p = 0.03) and oedema in the EMB. Seven (77.8%) patients with genetic cardiomyopathy had inflammation in the endomyocardial biopsy fulfilling the diagnostic criteria of inflammatory cardiomyopathy.Conclusion: Differentiating patients with a myocarditis from those with genetic cardiomyopathy can be challenging, even performing an EMB. Some patients with genetic cardiomyopathy fulfil the diagnostic criteria of inflammatory cardiomyopathy. Using invasive and non-invasive measures may be useful to develop a predictive model to differentiate myocarditis from genetic cardiomyopathy. What is Known: ⢠Acute myocarditis could present with cardiogenic shock in paediatric patients. ⢠Parvovirus B19 is the main cause of myocarditis in this population. What is New: ⢠Current diagnostic criteria for myocarditis have limited use in paediatric patients presenting with new-onset heart failure. ⢠Some patients with a genetic cardiomyopathy and a new-onset heart failure fulfill the diagnostic criteria of inflammatory cardiomyopathy.

Introducción y objetivos. Pasada 1 década desde el primer implante percutáneo de la válvula pulmonar (IPVP) Melody en España, se exponen sus resultados en cuanto a la función valvular y las complicaciones a corto y medio plazo. Métodos. Análisis descriptivo retrospectivo y multicéntrico nacional de los IPVP Melody en pacientes menores de 18 años desde el primer implante (de marzo de 2007 hasta el 1 de enero de 2016). Resultados. Se reclutaron 9 hospitales que contaban un total de 81 IPVP en 77 pacientes, cuyas medianas [intervalo intercuartílico] de edad y peso eran 13,3 [9,9-15,4] años y 46 [27-63] kg respectivamente. La enfermedad cardiaca más frecuente fue la tetralogía de Fallot (n = 27) y el sustrato anatómico más común, el conducto valvulado de yugular bovina (n = 31). Las incidencias de complicaciones intraprocedimiento y agudas fueron del 6 y el 8% (no hubo muertes periprocedimiento). La mediana del tiempo de seguimiento fue 2,4 [1,1-4,9] años. Se diagnosticó endocarditis infecciosa (EI) a 4 pacientes (5,6%), de los que 3 precisaron el explante de la válvula. En el periodo de seguimiento, la mortalidad fue del 1,3%, relacionada con EI. A los 5 años de seguimiento, el 80 ± 6,9% y el 83 ± 6,1% de los pacientes estuvieron libres de reintervención y recambio valvular pulmonar respectivamente. Conclusiones. El IPVP en pacientes pediátricos es una opción válida con buenos resultados hemodinámicos a corto y medio plazo. La incidencia de EI durante el seguimiento fue relativamente baja, si bien es la principal complicación que tener en cuenta (AU)
Introduction and objectives. A decade has passed since the first Spanish percutaneous pulmonary Melody valve implant (PPVI) in March 2007. Our objective was to analyze its results in terms of valvular function and possible mid-term follow-up complications. Methods. Spanish retrospective descriptive multicenter analysis of Melody PPVI in patients < 18 years from the first implant in March 2007 until January 1, 2016. Results. Nine centers were recruited with a total of 81 PPVI in 77 pediatric patients, whose median age and weight were 13.3 years (interquartile range [IQR], 9.9-15.4) and 46 kg (IQR, 27-63). The predominant cardiac malformation was tetralogy of Fallot (n = 27). Most of the valves were implanted on conduits, especially bovine xenografts (n = 31). The incidence of intraprocedure and acute complications was 6% and 8%, respectively (there were no periprocedural deaths). The median follow-up time was 2.4 years (IQR, 1.1-4.9). Infective endocarditis (IE) was diagnosed in 4 patients (5.6%), of which 3 required surgical valve explant. During follow-up, the EI-related mortality rate was 1.3%. At 5 years of follow-up, 80% ± 6.9% and 83% ± 6.1% of the patients were free from reintervention and pulmonary valve replacement. Conclusions. Melody PPVI was safe and effective in pediatric patients with good short- and mid-term follow-up hemodynamic results. The incidence of IE during follow-up was relatively low but was still the main complication (AU)

We report the usefulness of the Szabo (anchor-wire) technique and two modifications of such based on the same concept for stent implantation in congenital heart lesions. The modifications of the original technique are related to the localization of the cell of the stent through which the anchor wire, which stops the stent advancement, is introduced: proximal in the original technique and central or distal in the reported modifications. These techniques were performed in six patients: in two to maintain permeability of the ductus arteriosus, in three to achieve a fenestration of the interatrial septum, and in one to implant a stent in a right ventricle-to-pulmonary artery conduit close to the bifurcation. We describe the technique as well as the most important difficulties and complications encountered. The Szabo or anchor-wire technique concept is a new tool for stent implantation that can provide more accurate stent positioning compared with conventional angiographically guided implantation in different congenital heart defects. As with any new tool, this technique demands a learning curve and knowledge of potential complications.

INTRODUCTION AND OBJECTIVES: A great variety of different types of vascular fistula are referred to cardiac catheterization laboratories for diagnosis and percutaneous occlusion. In addition, a wide range of devices is available for treating them percutaneously. The objectives of this study were to assess the usefulness and difficulty of treating vascular fistulas percutaneously using controlled-release coils or Amplatzer vascular plugs and to report on the complications and overall outcomes observed with these two devices. METHODS: Retrospective review of percutaneous embolizations performed from January 2004 through June 2008. RESULTS: In total, 51 vascular fistulas in 30 patients aged from 6 days to 28 years (mean, 8.4 years) underwent successful embolization. The underlying diagnoses were: 27 venous collaterals in 16 patients after the Glenn procedure, four surgical (i.e. Blalock-Taussig) fistulas, 11 pulmonary arteriovenous fistulas in three patients, two aortopulmonary collateral arteries in two patients, one venous collateral in a patient who underwent the Fontan procedure, one aortopulmonary artery fistula in a patient with Scimitar syndrome, one coronary arteriovenous fistula, three systemic arteriovenous fistulas in a newborn, and one fistula from the left atrium to the superior vena cava after the repair of anomalous pulmonary venous return. The lesions were treated percutaneously using 34 vascular plugs and 19 coils. CONCLUSIONS: Vascular fistulas can be occluded percutaneously with good RESULTS: Small fistulas can be closed using coils, while vascular plugs are preferable for large lesions. Both devices are highly effective as occluders and no particular difficulty or significant complication was observed.

Introducción y objetivos. Hay gran variedad de fístulas vasculares que son remitidas a los laboratorios de cateterismo cardiaco para su diagnóstico y oclusión percutánea. Existe también una amplia gama de dispositivos utilizables en su tratamiento percutáneo. El objetivo es evaluar la utilidad, las dificultades, las complicaciones y los resultados en el tratamiento percutáneo de las fístulas vasculares mediante el uso de coils de liberación controlada o tapones vasculares de Amplatzer. Métodos. Revisión retrospectiva de las embolizaciones percutáneas realizadas desde enero de 2004 a junio de 2008. Resultados. Se embolizaron 51 fístulas vasculares en 30 pacientes con edades entre 6 días y 28 años (media, 8,4 años), con buen resultado. Diagnósticos: 27 colaterales venosas en 16 pacientes con Glenn; 4 fístulas quirúrgicas (Blalock-Taussig); 11 fístulas arteriovenosas pulmonares en 3 pacientes; 2 arterias colaterales aortopulmonares en 2 pacientes; 1 colateral venosa en 1 paciente con Fontan previo; 1 arteria aortopulmonar en un síndrome de cimitarra; 1 fístula arteriovenosa coronaria; 3 fístulas arteriovenosas sistémicas en 1 recién nacido, y una fístula entre aurícula izquierda y vena cava superior tras la cirugía de un retorno venoso pulmonar anómalo. En el tratamiento percutáneo de estas lesiones se emplearon 34 tapones vasculares y 19 coils. Conclusiones. Las fístulas vasculares pueden ser ocluidas percutáneamente con buen resultado. Los coils permiten el cierre de fístulas de menor diámetro y los tapones vasculares están indicados en las más amplias. Ambos dispositivos alcanzan una alta eficacia oclusora y no se han observado especiales dificultades ni complicaciones significativas (AU)
