The Coronavirus disease 2019 (COVID-19) pandemic has thoroughly and deeply affected the provision of healthcare services worldwide. In order to limit the in-hospital infections and to redistribute the healthcare professionals, cardiac percutaneous intervention in Pediatric and Adult Congenital Heart Disease (ACHD) patients were limited to urgent or emergency ones. The aim of this article is to describe the impact of the COVID-19 pandemic on Pediatric and ACHD cath laboratory activity during the so-called 'hard lockdown' in Italy. Eleven out of 12 Italian institutions with a dedicated Invasive Cardiology Unit in Congenital Heart Disease actively participated in the survey. The interventional cardiology activity was reduced by more than 50% in 6 out of 11 centers. Adolescent and ACHD patients suffered the highest rate of reduction. There was an evident discrepancy in the management of the hard lockdown, irrespective of the number of COVID-19 positive cases registered, with a higher reduction in Southern Italy compared with the most affected regions (Lombardy, Piedmont, Veneto and Emilia Romagna). Although the pandemic was brilliantly addressed in most cases, we recognize the necessity for planning new, and hopefully homogeneous, strategies in order to be prepared for an upcoming new outbreak., (Copyright © 2021 Italian Federation of Cardiology - I.F.C.

: The recent outbreak of 2019 severe acute respiratory syndrome coronavirus-2 is having major repercussions on healthcare services provision in Italy and worldwide. Data suggest the virus has a strong impact on the cardiovascular system, and cardiac imaging will play an important role in patients affected by coronavirus disease-2019. Although paediatric patients are mildly affected, they represent a clear accelerator in spreading the virus, and healthcare workers are at higher risk of infection. The aim of this position paper is to provide clinical recommendation regarding the execution of imaging investigations for the cardiac diagnostic work-up of paediatric patients with suspected or confirmed infection.

Background: Left ventricular noncompaction cardiomyopathy (LVNC) is associated with poor clinical outcome in childhood. Standard diagnostic criteria are still controversial, especially in young patients. Recent studies in adults demonstrated that left ventricular (LV) twist is abnormal in LVNC, but it has not been investigated in pediatric patients to date. Our aim was to assess LV cardiac mechanics, LV twist, and the prevalence of rigid body rotation, using 2-dimensional speckle tracking echocardiography, in young patients with LVNC and LV hypertrabeculation., Methods: Forty-seven children (age range: 0-18 years) were assessed for suspected LVNC. All patients underwent 2-dimensional speckle tracking echocardiography and cardiovascular magnetic resonance imaging at 1.5 Tesla (T). Twenty-three patients fulfilled the cardiovascular magnetic resonance imaging diagnostic criteria for LVNC (LVNC group), while the remaining 24 did not and were included in the LV hypertrabeculation group. Forty-seven age- and sex-matched healthy volunteers were used as controls., Results: The average LV twist was significantly reduced in LVNC compared with control and LV hypertrabeculation. Rigid body rotation was recognized in 13 (56%) children with LVNC and in 1 (4%) child with LV hypertrabeculation and a strong family history for LVNC. Multivariable analysis demonstrated that LV twist is an independent predictor of LVNC ( P=0.006; coefficient=0.462). The receiver operating characteristics curve showed that LV twist had optimal predictive value to discriminate patients with LVNC (cutoff value <5.8°; sensitivity, 82%; specificity, 92%; area under the curve=0.914)., Conclusions: LV twist has good predictive value in diagnosing LVNC in young patients. Our findings strongly support the routine use of 2-dimensional speckle tracking echocardiography in the evaluation of young patients with suspected LVNC.
