Background: Information on understanding the mediating role of resilience in the relationship between posttraumatic growth (PTG) and positive and negative stress among students is limited. The objective of this research was to evaluate the mediating role of resilience in the relationship between positive and negative stress and PTG in university students., Methods: The research was carried out using an associative strategy with an empirical approach and explanatory design, with a sample of 507 participants whose average age was 22.38 years ([Formula: see text]= 3.758), the sample was mostly composed of women (70.4%)., Results: The results allow us to describe that resilience plays a complete mediating role in the relationship between negative stress and PTG. On the other hand, mediation was partial when resilience mediated the relationship between positive stress and PTG. In addition, multigroup invariance analyses according to gender and geographic context show that there is no difference in males, females, and the region where they reside., Conclusion: In conclusion, the hypothesis that resilience fulfills the mediating function is ratified., (© 2023.

Objective: During the last 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 (MICS) and control patients who were approached in a conventional manner (CONV). 122 patients were admitted, with a mean age (MICS: 6, 4-12 vs. CONV: 5, 2-8 years). No differences were found in the baseline characteristics of both groups. No statistically significant difference was documented in infusion times (MICS: 67 min [50-90] vs. CONV: 53 min [42-90]; 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 ICU 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., Patients with congenital heart disease that involves reconstruction of the right ventricular outflow tract must frequently undergo interventions derived from the limited useful life of the surgical canals, which leads to the development of right ventricular 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 right ventricular dilatation. The standard technique for the implantation of the Melody pulmonary valve was used, without complications during the procedure or one 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., (Copyright: © 2020 Permanyer.)

Balloon atrial septostomy (BAS) is a palliative procedure performed in the preoperative management of patients with transposition of great arteries (TGA), to improve the mixing of blood between the 2 systems. This report describes experience at the Clínica Cardiovascular Santa Maria in Medellin, Colombia. Between 2002 and 2010, 22 patients with TGA underwent BAS. Patient age at the time of the procedure was 21 days on average; 68% of patients were male. Average weight was 2.96 kg and interatrial gradient was between 4 and 12 mm Hg. The average systemic oxygen saturation at the beginning of the procedure was 60%, with a final saturation of 90%. Z5 atrioseptostomy balloons were used in 18 patients (81%), using Rashkind technique; Tyshak balloon catheters were used in 3 patients (13%) with the Shrivastava technique; and static high-pressure peripheral angioplasty balloons were used in 3 patients (13%). Two patients underwent BAS with 2 types of balloons. Although there were no complications clearly attributable to the procedure, 14% of patients had evidence of focal brain injury on the postoperative magnetic resonance image. Six patients died (27%), 5 of them because of postoperative complications and 1 because of infectious complications at another institution. All postoperative deaths occurred before 2006. The BAS is a safe technique for preoperative stabilization of patients with TGA.

Uhl's anomaly is a rare cardiomyopathy characterized by a thin walled dilated right ventricle due to the absence of myocardium. This could be due to an alteration in embriological development or the presence of massive apoptosis in the right ventricle myocardium. It generally manifests as cardiac failure, and the diagnosis is made by echocardiography and magnetic resonance. The response to medical treatment is poor and there is no known ideal treatment. Isolated cases of different surgical options have been described that include cardiac transplant, but there is still a poor prognosis and a high mortality rate. The case of a 10 year old girl with six months of thoracic pain and decreased exercise tolerance with echocardiographic and resonance findings characteristic of Uhl's anomaly is presented.
