[Pediatric telecardiology experience in the COVID-19 pandemic context]. / Experiencia en telecardiología infantil en el contexto de la pandemia de COVID-19.

Introduction: The COVID-19 pandemic has caused a global impact on public health services. Using new strategies through telehealth for the management of patients with congenital heart disease was the challenge. Objective: To describe the experience in telecardiology, and the strategies implemented during the pandemic. Method: Retrospective, qualitative study that includes the period from April 2020 to April 2021. Inquiries were received through the service's official e-mail or telephone. They were classified according to the type of concern and complexity of heart disease using color coding. The responses were asynchronous (by e-mail) or synchronous (videoconferences). The videoconferences were made using a secure platform (Cisco-Webex). Results: From April 2020 to April 2021, a total of 3372 queries were answered. The responses were distributed via e-mail (64.9%), phone calls (1.2%) and videoconferences (14.5%). The most frequent reasons for consultation were the request for missed appointments (68%), and remote clinical monitoring (20%). A total of 2296 families was contacted. Only 14.1% of the inquiries were cited in person. With color coding, a stratification was performed according to urgency. Conclusions: Telehealth proved to be a useful tool for the clinical management of patients with congenital heart disease in their place of origin. It prevented a considerable number of transfers, identified patients at risk rapidly, comforted families, and strengthened ties with local hospitals that make up the health network.

Congenitally corrected transposition of the great arteries outcomes of different surgical techniques in a paediatric population: A single-centre report.

BACKGROUND: Congenitally corrected transposition of the great arteries is a complex pathology characterised by atrioventricular and ventriculo-arterial discordance. Optimal surgical approaches are still a matter of debate. OBJECTIVE: To evaluate the outcomes of different surgical treatments in a single centre. METHODS: Between 1998 and 2020, 89 patients were studied. The cohort was divided into three groups: physiologic, anatomic, and univentricular repair. RESULT: Physiologic correction (56.18%) was associated with significant tricuspid valve regurgitation progress (42%) and complete AV block (30%) compared to anatomic repair. Right ventricular systolic dysfunction was developed in 14%. Instead, anatomic correction (30.34%) (double switch 59% and Rastelli type 40.7%) presented moderate to severe aortic regurgitation (4%) and left ventricular systolic dysfunction (11%). Complete AV block was developed in 14.8%. Rate of reintervention was 34% for physiologic and 26% for anatomic. Univentricular palliation (13.8%) presented no complications or late mortality during the follow-up. The overall survival at 5 and 10 years, respectively, was 80% (95% CI 69, 87) and 75% (95% CI 62, 84). There was no statistically significant difference in mortality between the groups (p log-rank = 0.5752). CONCLUSION: Management of congenitally corrected transposition of the great arteries remains a challenge. In this cohort, outcomes after physiologic repair were satisfactory in spite of the progression of tricuspid regurgitation and the high incidence of AV block. Anatomic repair improved tricuspid regurgitation but increased the risk of aortic regurgitation and left ventricular systolic dysfunction. The Fontan group showed the lowest incidence of complications.

Everolimus for cardiac rhabdomyomas in children with tuberous sclerosis. The ORACLE study protocol (everOlimus for caRdiac rhAbdomyomas in tuberous sCLErosis): a randomised, multicentre, placebo-controlled, double-blind phase II trial.

INTRODUCTION: Tuberous sclerosis complex is a rare genetic disorder leading to the growth of hamartomas in multiple organs, including cardiac rhabdomyomas. Children with symptomatic cardiac rhabdomyoma require frequent admissions to intensive care units, have major complications, namely, arrhythmias, cardiac outflow tract obstruction and heart failure, affecting the quality of life and taking on high healthcare cost. Currently, there is no standard pharmacological treatment for this condition, and the management includes a conservative approach and supportive care. Everolimus has shown positive effects on subependymal giant cell astrocytomas, renal angiomyolipoma and refractory seizures associated with tuberous sclerosis complex. However, evidence supporting efficacy in symptomatic cardiac rhabdomyoma is limited to case reports. The ORACLE trial is the first randomised clinical trial assessing the efficacy of everolimus as a specific therapy for symptomatic cardiac rhabdomyoma. METHODS: ORACLE is a phase II, prospective, randomised, placebo-controlled, double-blind, multicentre protocol trial. A total of 40 children with symptomatic cardiac rhabdomyoma secondary to tuberous sclerosis complex will be randomised to receive oral everolimus or placebo for 3 months. The primary outcome is 50% or more reduction in the tumour size related to baseline. As secondary outcomes we include the presence of arrhythmias, pericardial effusion, intracardiac obstruction, adverse events, progression of tumour reduction and effect on heart failure. CONCLUSIONS: ORACLE protocol addresses a relevant unmet need in children with tuberous sclerosis complex and cardiac rhabdomyoma. The results of the trial will potentially support the first evidence-based therapy for this condition.

Takayasu arteritis in paediatrics.

Takayasu arteritis is an idiopathic chronic granulomatous panarteritis predominantly affecting the aorta and its main branches. Although idiopathic, genetic contribution to disease susceptibility is being increasingly recognised. Rare in children, Takayasu arteritis is a worldwide disease with significant morbidity and mortality. Its diagnosis is a challenge and requires awareness of the condition as clinical features at presentation are non-specific and assessing disease activity is difficult. In the inflammatory stage, treatment is essential to prevent the insidious course and vascular damage: stenotic, occlusive lesions, aneurysms, and aortic regurgitation. New imaging modalities, such as CT scan, MRI, and 18F-fluorodeoxyglucose positron emission tomography, have expanded the possibilities for non-invasive diagnosis and monitoring; however, digital subtraction arteriography remains the gold standard for the diagnosis of Takayasu arteritis. Steroids are the first-line medical treatment. The combined use of methotrexate, cyclophosphamide, azathioprine, mycophenolate mofetil, and biological agents is common. Revascularisation therapy should be considered in uncontrolled hypertension secondary to renal artery stenosis, symptomatic coronary ischaemia, cerebrovascular disease, severe aortic regurgitation, limb ischaemia, and aneurysms at risk of rupture, using surgical or endovascular procedures and taking into consideration that complications, especially restenosis, are frequent. Disease activity increases the likelihood of complications after revascularisation. Surgical intervention has shown better long-term outcomes, although the endovascular approach is evolving. The aim of this review was to describe key points of the diagnosis, treatment, and follow-up of Takayasu arteritis in childhood.

Tratamiento endovascular en arteritis de Takayasu: Presentación de un caso clínico / Endovascular intervention in Takayasu Arteritis: Case report

Una paciente de cuatro años concurrió a la Guardia por edemas e hipertensión arterial. Al momento del examen físico, se detectó disminución del pulso en el brazo izquierdo y ausente en los miembros inferiores, con diferencia de tensión arterial mayor de 10 mmHg entre los miembros superiores. Se realizó un ecocardiograma, en el que se observó coartación grave de la aorta a nivel abdominal y disfunción ventricular. Con la sospecha de arteritis de Takayasu, se completaron estudios con angiotomografía cardíaca, que confirmó una desconexión de la arteria subclavia izquierda y estrechez grave en la aorta abdominal. El diagnóstico definitivo fue de arteritis de Takayasu. Se realizó una angioplastía con estent por Hemodinamia en la aorta abdominal, con buenos resultados posteriores. Mejoraron los pulsos de los miembros inferiores, y se obtuvieron valores normales de la tensión arterial. En el ecocardiograma, mejoró la función ventricular, y el gradiente en la zona de coartación se redujo significativamente.

A four year old patient with no medical history was admitted to our hospital's Emergency Department, suffering from edema and hypertension. During physical examination a low pulse was detected in the left arm and a lack of pulses in lower limbs, with a blood pressure difference greater than 10 mm Hg between both arms. An echocardiogram demonstrated severe aortic abdominal coarctation and ventricular dysfunction. Takayasu arteritis was diagnosed and cardiac angiography was performed. Disconnection of left subclavian artery and severe tightness at the abdominal aorta were confirmed. The definitive diagnosis was Takayasu arteritis. Angioplasty with stent was performed in abdominal aorta, with good subsequent results. The pulses improved in the lower limbs, and normal blood pressure values without gradient between all members were registered. The echocardiogram improved ventricular function and the gradient in the coarctation area was significantly reduced.
