Objective: During the past decades, cardiac surgery has revolutionized; there is a growing interest in minimizing the physical aggression of surgical procedures, seeking a quick recovery, minimally invasive approaches have been a trend in recent years, with safety and efficacy equivalent to traditional techniques sternotomy. The objective of this study is to compare clinical results between pediatric patients with congenital heart disease undergoing minimally invasive surgery versus standard sternotomy. Methods: Case-control study, nested in a retrospective cohort. All pediatric patients over 10 kg in weight were included, between 2014 and 2019 who underwent surgical correction of simple congenital heart disease, in a cardiovascular center in Medellin. A case was defined as one that underwent a minimally invasive approach (minimally-invasive cardiac surgeries [MICS]) and control patients who were approached in a conventional manner (CONV). 122 patients were admitted, with a mean age (MICS: 6,(4)(5)(6)(7)(8)(9)(10)(11)(12)(2)(3)(4)(5)(6)(7)(8). No differences were found in the baseline characteristics of both groups. No statistically significant difference was documented in infusion times ; p = 0.54), nor differences in complications (MICS: 7.4 vs. CONV: 8.8%; p = 0.77). MICS patients had lactate on admission and a shorter intensive care unit stay than controls. Conclusion: The MICS approach turns out to be a novel, less invasive, safe and efficient technique compared to the conventional surgical approach for the repair of simple congenital heart disease in pediatric patients.

Los pacientes con cardiopatías congénitas que afectan la continuidad del ventrículo derecho con la arteria pulmonar deben someterse con frecuencia a intervenciones debido a la limitada vida útil de los conductos quirúrgicos, lo que lleva al desarrollo de disfunción ventricular derecha por cambios en la geometría ventricular y predisposición a arritmias letales, con el consiguiente riesgo de reintervenciones. El implante valvular percutáneo pulmonar es una nueva alternativa terapéutica, menos invasiva en comparación con la quirúrgica, para pacientes seleccionados. Se realiza una revisión de las publicaciones médicas actuales disponibles y se describe la experiencia inicial del implante valvular pulmonar percutáneo en un centro colombiano de alta complejidad para el tratamiento de enfermedades cardiovasculares, en dos pacientes con disfunción del homoinjerto aórtico en posición pulmonar con doble lesión valvular, en los cuales el implante valvular pulmonar percutáneo fue una conducta exitosa. Se eligió a pacientes con cardiopatías congénitas, conductos quirúrgicos disfuncionales con estenosis o insuficiencia pulmonar significativa, y disfunción y dilatación ventricular derechas. Se empleó la técnica regular para el implante de la válvula pulmonar Melody, sin documentarse complicaciones durante el procedimiento ni al año de seguimiento. El implante percutáneo de la válvula pulmonar es un gran avance en el tratamiento de pacientes con cardiopatías congénitas, con resultados favorables a corto y mediano plazos, lo cual hace posible la restauración de la función ventricular con riesgo mínimo, frente al reemplazo quirúrgico en pacientes seleccionados.

Left atrial appendage aneurysm (LAAA) is a rare cardiac pathology that is often identified in adulthood. There are a myriad of presentations related to atrial appendage enlargement, but most are asymptomatic. Pediatric cases of LAAA are extremely rare. We report a case of an incidental giant LAAA found in a healthy 6-year-old boy. He was successfully treated with surgical resection. A review of the literature shows that the presentation of LAAA in pediatrics likely involves cardiac or respiratory symptoms but can also be incidental findings. Similar to adults, diagnosis requires cardiac imaging, with echocardiography being the mainstay. Surgical intervention is indicated in symptomatic and most asymptomatic patients to prevent complications. More research is warranted into the optimal timing of surgery and alternative surgical approaches for complex cases.

Patients with congenital heart disease that involves reconstruction of the right ventricular (RV) outflow tract must frequently undergo interventions derived from the limited useful life of the surgical canals, which leads to the development of RV dysfunction due to changes in the ventricular geometry and predisposition to lethal arrhythmias, with the consequent risk of reinterventions. The percutaneous pulmonary valvular implant is a new therapeutic alternative, less invasive, compared to surgery, for selected patients. A review of the available literature is made, and the initial experience of percutaneous pulmonary valve implantation in a Colombian center of high complexity for the treatment of cardiovascular diseases is described, in two patients with aortic homograft dysfunction in a pulmonary position with double valvular lesion, in which the percutaneous pulmonary valve implant was a successful strategy. Patients with congenital heart disease were chosen, with dysfunctional surgical conduits with stenosis or significant pulmonary insufficiency, with dysfunction and RV dilatation. The standard technique for the implantation of the Melody pulmonary valve was used without complications during the procedure or 1 year of follow-up. Percutaneous implantation of the pulmonary valve is a great advance in the management of patients with congenital heart diseases, with favorable results in the short and medium-term, allowing the restoration of ventricular function with minimal risk, compared to surgical replacement in selected patients.
