ABSTRACT
This paper shows a selection of the most relevant articles in congenital heart diseases in the last year. About intervencional procedures, we comment the latest guidelines in 2021, as well as some interesting papers on the implementation of materials and techniques in the field of percutaneous treatment of congenital heart diseases. In cardiac imaging, we focus on articles related to the revolutionary advance of 4D-NMR and 3D echo in the study of these congenital diseases. Respect pediatrics, there are interesting studies about multisystem inflammatory syndrome linked to SARS-CoV-2 (MIS-C) and also in the field of hypertrophic cardiomyopathy. Related to surgery, we comment the hybrid technique for treating hypoplastic left ventricle. Finally, regarding arrhythmias in congenital heart disease, we focus our attention on atrial fibrillation, due to the peculiarities that exist in this type of patients.

ABSTRACT
AIMS & OBJECTIVES: multisystem inflammatory syndrome in children (MIS-C) is a concerning entity associated to SARS-CoV-2 infection. Reported hospital and pediatric intensive care unit (PICU) admission rates are as high as 88% and 80% respectively. Cardiovascular involvement including shock, ventricular systolic dysfunction or coronary artery (CA) anomalies has been reported as a feature of MIS-C. Our objective is to describe the cardiovascular features of children with severe MIS-C during their admission PICU admission and up to 3-months follow-up. METHODS: single center observational retrospective study. RESULTS: seven children (1/7 female, median age of 10.6 years and range 4.8-13.8) were admitted between April 16th and May 5th 2020. SARS-CoV-2 infection diagnosis was made by respiratory reverse transcriptase polymerase chain reaction or serological tests. All children had shock that was treated with intravenous fluids (median 15 mL/Kg, range 10-30) and norepinephrine infusions (median dose 0.16 mcg/Kg, range 0.05-0.33). Left ventricular dysfunction on echocardiogram defined as a left ventricular ejection fraction (LVEF) < 55% was present in 2/7 patients during PICU admission and 4/7 had CA anomalies. 2/7 patients had altered EKGs (diffuse altered repolarization and prolonged PR interval). Troponin-I was elevated in 7/7 (median 107.3 ng/L, range 30-355) as was N-terminal pro-brain natriuretic peptide (median 12,033 pg/mL, range 1071-34547). All patients had normal LVEF and CAs at 1, 2 and 3-months follow-up. 1/7 patient had an altered EKG at 1-month follow-up that resolved later. CONCLUSIONS: cardiac involvement in severe MIS-C appears to be common and severe but limited in time and with good outcomes.
