Resumen Introducción: Las cardiopatías congénitas son las anomalías congénitas más comunes en recién nacidos con una prevalencia de 1%. El cateterismo cardíaco diagnóstico y terapéutico ha revolucionado el tratamiento de estas enfermedades, aunque puede acompañarse de complicaciones. Objetivo: Describir la incidencia y el tipo de complicaciones vinculadas con el cateterismo cardíaco pediátrico en un centro de referencia para cardiopatías congénitas. Método: Estudio observacional retrospectivo, con intención analítica a partir de registros de cateterismos cardíacos realizados a pacientes con cardiopatías congénitas y adquiridas. Resultados: Se incluyeron 2,688 registros durante nueve años consecutivos. El 53.9% correspondió a hombres, 21.3% con edades de dos a cinco años y 20.3% de seis meses a dos años. El 63.5% de los procedimientos fue electivo. La prevalencia de complicaciones en las primeras 24 horas posteriores al cateterismo fue de 6.7% (4.2% menores y 2.4% mayores). En el 0.8% de los procedimientos sobrevino la muerte temprana. Los factores relacionados con las complicaciones fueron: edad al momento del cateterismo <28 días (OR, 2.18; IC 95%, 1.28-3.70), saturación de oxígeno antes del cateterismo <79% (OR, 2.15; IC 95%, 1.02-4.53), uso de inotrópicos antes del cateterismo (OR, 3.00; IC 95%, 1.68-5.33). Las variables incluidas en el modelo explican el 38% de la varianza de las complicaciones posteriores al cateterismo cardíaco en pacientes menores de 18 años. Conclusiones: En este estudio, el cateterismo cardíaco se vinculó con complicaciones mayores y menores, incluida la muerte. Los factores adjuntos fueron edad menor de 28 días, menor saturación de oxígeno y uso de inotrópicos antes del cateterismo.

Ventricular diverticulum is a rare congenital malformation. Although most patients are asymptomatic, it can present with rupture and sudden death, for which surgical repair is indicated. The authors report the case of a 5-year-old boy with a prenatal diagnosis of an isolated left ventricular diverticulum. It was decided for surgical closure; however, a persisting leakage at the patch repair site was observed, for which a transcatheter percutaneous closure approach was used, achieving complete occlusion of the defect. Transcatheter closure of suitable ventricular diverticula is a safe and effective option.

Introduction:Congenital heart diseases are the most common congenital abnormalities in newborns with a prevalence of 1%. Therapeutic and diagnostic cardiac catheterization has revolutionized the treatment of these diseases; however, it can be associated with complications. Objective: To describe the incidence and type of complications associated with pediatric cardiac catheterization in a reference center for congenital heart defects. Methodology: Retrospective observational study, with analytical intention based on records of cardiac catheterization, performed on patients with congenital and acquired heart disease. Results: Two thousand six hundred and eighty-eight records were included for nine consecutive years. About 53.9% were men, 21.3% with ages between 2 and 5 years, and 20.3% between 6 months and 2 years. About 63.5% of the procedures were elective. The prevalence of complications in the first 24 h after catheterization was 6.7% (4.2% minor and 2.4% major). Early death occurred in 0.8% of the procedures. Factors associated with complications were age at catheterization < 28 days (odds ratio OR 2.18,), precatheter oxygen saturation < 79% (OR 2.15,), use of pre-catheter inotropics (OR 3.00,). The variables included in the model explain 38% of the variance of post-cardiac catheterization complications in patients younger than 18 years. Discussion: Cardiac catheterization is associated with major and minor complications including death. The associated factors were < 28 days, lower oxygen saturation, and use of pre-catheter inotropics.
