While sinus node dysfunction requiring pacemaker implantation may be required after surgical repair, this has not been previously reported after covered stent implantation. We reviewed the experience in two interventional centers. Balloon inflation in the superior vena cava was used to confirm the anomalous pulmonary vein drainage would be unobstructed after stent implantation. During balloon testing in 62 consecutive patients, we assessed gradients across the pulmonary vein to left atrium while monitoring the rhythm. We observed the outcomes after covered stent correction in 51 patients. In a single patient, significant bradycardia and pauses developed on repeat balloon testing and the procedure was abandoned without stent implantation. In another patient, there was no sign of sinus node dysfunction during balloon testing but several hours after ...

Our study focused on evaluating the levels of circulating endothelial progenitor cells and circulating endothelial cells in patients with congenital left-to-right shunts and pulmonary hypertension undergoing definitive repair. Endothelial progenitor cells (identified by simultaneous co-expression of CD45dim, CD34 + and KDR2 + surface antibodies) and circulating endothelial cells (identified by simultaneous co-expression of inherent antibodies CD45-, CD31+, CD146 + and CD105+) were prospectively measured in seventy-four children (including children with Down syndrome), median age six years (2.75–10), with clinically significant left-to-right shunts undergoing transcatheter or surgical repair and compared to thirty healthy controls. Endothelial progenitor cells and, particularly,...

This study aimed to evaluate the clinical and surgical results of pediatric patients with KD and cardiac sequelae who underwent coronary artery bypass grafting. Methods: A retrospective study was carried out. Patients with a diagnosis of KD and cardiac sequelae who underwent coronary artery bypass grafting from January 1, 2004, through March 31, 2021, were included: preoperative characteristics and conditions. Results: Ten patients were included, with a mean age of 6.4 ± 3.7 years; 80% males. Seven (70%) had the compromise of 2 coronary arteries, the most affected being the left anterior descendent artery (36.9%) with aneurysm and the right coronary artery (36.8%) with stenosis. 40% had preoperative moderate-to-severe ventricular dysfuncti...

The experience of our department showed that the execution of a strict surgery protocol, universal severe acute respiratory syndrome coronavirus 2 screening, surgical prioritization, and an orderly reactivation of the cardiac surgery program is a feasible way to keep congenital heart diseases surgery program.

They were diagnosed with absence of connection between the main pulmonary artery (MPA) and right pulmonary artery (RPA) and bilateral ductus arteriosus, with the RPA originating from the ductus arteriosus. Treatment was approached with a hybrid strategy: percutaneous intraluminal angioplasty with a right intraductal stent and device closure of the left ductus arteriosus and followed by surgical reconstruction with interposition of a graft from RPA to MPA. Both patients had a favorable outcome.

La reintervención quirúrgica ha sido el tratamiento habitual, pero se acompaña de alta morbimortalidad. El cierre transcatéter es una alternativa terapéutica. El objetivo del presente estudio es analizar la factibilidad y los resultados a corto y mediano plazo del cierre transcatéter de fugas paravalvulares con dispositivos oclusores. Métodos: Registro unicéntrico de una serie consecutiva de pacientes con fugas paravalvulares posquirúrgicas que fueron cerradas vía transcatéter con dispositivos oclusores, entre enero del 2006 y diciembre del 2016. Se analizaron los resultados de eficacia y seguridad durante el procedimiento y a seis meses. Resultados: Se trataron 21 fugas paravalvulares (15 mitrales, 5 aórticas y 1 tricuspídea) durante 20 procedimientos. El 91% de las fugas fue grave en la ecocardiografía inicial. El dispositivo utilizado con más frecuencia fue el Amplatzer Vascular Plug III ® en 10 procedimientos (50%). Se utilizó ecocardiografía transesofágica tridimensional en 70% de los casos. Se logró implantar el dispositivo con éxito en el 95% de los casos; se consiguió una reducción ≥ 1 del grado de regurgitación en el 95% de las veces y se alcanzó el éxito clínico en el 79%. A seis meses la supervivencia fue del 100%; sin embargo, tres casos requirieron cirugía valvular (15%). Conclusiones: El cierre transcatéter de fugas paravalvulares es un procedimiento factible, seguro y con tasas elevadas de éxito técnico, ecocardiográfico y clínico a corto y mediano plazo. Es una alternativa terapéutica adecuada, en particular en pacientes considerados de alto riesgo quirúrgico y múltiples comorbilidades.

A single-center retrospective review of all bypass surgeries performed over a 10-year period (2003-2012). Of a total of 2325 patients registered in our database, the DSC group included 259 cases (11%), and the remaining 2066 cases (89%) constituted the control group (PSC). RACHS-1 risk was higher for the DSC group (74% had a score of 3 or 4) than for the PSC group (82% had a score of 2 or 3). The most frequent diagnosis for the DSC group was transposition of the great arteries (28%). We found out that hemodynamic instability was the main indication observed in patients aged ≤ 8 years (63%), while bleeding was the principal indication for patients aged ≥ 8 years (94%) ( ≤ 0.001). The average time between surgery and sternal closure was 2.3 ± 1.4 days. Overall mortality rates were higher for patients of the DSC group (22%) than for t...

We report our experience in the correction of this heart disease with a handmade bovine pericardial-valved woven Dacron conduit as an alternative procedure to homografts, with a focus on early, mid-term, and long-term results. We designed a retrospective study that included 15 patients with a mean age of 1.5 years (range: three months to eight years), who underwent primary repair of simple CAT. Right ventricular outflow tract was reconstructed in all the cases with this handmade graft that was explanted at the time of its biological stenotic degeneration. A peeling procedure was performed at this time, in order to reconstruct the right ventricle-to-pulmonary artery continuity. Overall mortality was 13.3% (one death at the early postoperative primary repair and the other at the mid-term postoperative peeling reoperation). Actuarial survival rate was 93.3%, 86.7%, and 86.7% a...

La circulación extracorpórea (CEC) afecta negativamente la función ventricular e incrementa la presión pulmonar en el postoperatorio. Se presume que la cirugía de Fontan sin CEC reduce la morbilidad a corto plazo, así como la estancia intrahospitalaria. Objetivo: Comparar los resultados obtenidos en pacientes operados de Fontan con y sin CEC. Método: Estudio retrospectivo de pacientes operados de Fontan de enero 2008 a diciembre 2012. Se hizo la distribución por grupos de acuerdo al uso de CEC y se realizó el análisis comparativo. Resultados: Se operaron 10 pacientes sin CEC. El perfil preoperatorio mostró una discrepancia en la edad promedio, siendo menor para el grupo sin CEC. Alrededor del 80% de los pacientes en ambos grupos presentaban algún tipo de paliación previa. En la mitad de los casos se utilizó un injerto de 18 mm; todos los injertos se fenestraron. La estancia intrahospitalaria fue similar en ambos grupos, hubo un menor requerimiento de inodilatadores, vasopresores y óxido nítrico en el grupo sin CEC. No hubo decesos en los pacientes operados sin CEC. Al seguimiento, la mayoría de los pacientes se encontraban en clase funcional i. Conclusiones: En nuestra experiencia la técnica sin CEC ofrece resultados similares a corto y mediano plazo comparada con la técnica convencional.

We analyzed these variables: age at the surgical moment, sex, congenital heart defect, pulmonary arterial pressure, type of surgery, time of stay in the intensive care unit, complications and mortality. In this period they were surgically treated 37 patients. The mean age was of 2 years with 8 months with a range of 2 months to 17 years. The interventricular defect was the most frequent one (35%) and it was associated to persistent ductus arteriosus in the 61% of the cases. Six patients (16%) had atrioventricular septal defect, the half of them type A and other half type C of Rastelli classification. Twelve patients (32%) had one lesion persistent ductus arteriosus. Three patients had tetralogy of Fallot and two at...
