Manifestaciones cardíacas y hallazgos ecocardiográficos post infección del síndrome inflamatorio multisistémico asociado al COVID-19 en pacientes pediátricos. Hospital Vicente Corral Moscoso, Cuenca, abril de 2020 – marzo 2022

Abstract

Background: Since the beginning of 2020, the entire world has been in a pandemic situation due to SARS-CoV-2, which causes the COVID-19 disease. This mainly affects the adult population; However, it has been shown that cardiac manifestations of the multisystem inflammatory syndrome associated with COVID-19 disease appear in the pediatric population. Objective: To analyze the cardiac manifestations and post-infection echocardiographic findings of the multisystem inflammatory syndrome associated with COVID-19 in pediatric patients, at the “Vicente Corral Moscoso” Hospital in Cuenca, during the period April 2020 to March 2022. Methods: A quantitative, descriptive and transversal study was carried out. The medical records and echocardiograms of 25 pediatric patients infected with COVID-19 were reviewed. Results: 31.6% of the patients were between 1 and 4 years old, 52.6 were female and 63.2% were overweight. The main comorbidity found was the presence of overweight or obesity in 84.2%; The main signs were fever (68.4%), vomiting (47.4%) and abdominal pain (42.1%). The echocardiographic findings found were pericardial effusion (15.8%) and right ventricular dysfunction (5.3%). The main multisystem cardiac manifestations were pericardial dysfunction (10.5%), valvular dysfunction (10.5%), cardiac arrhythmias (10.5%), and pericardial effusion (10.5%). The 26.3% of the patients died. Conclusions: A clear relationship was observed between inflammatory symptoms and cardiac complications after COVID-19 infection.
