AI Article Synopsis
- The study highlights the need for effective surveillance of cardiac implantable electronic devices (CIEDs) in pediatric and congenital heart disease patients, as recommendations for this group are limited.
- Data showed low rates of actionable events during routine remote monitoring, particularly in asymptomatic patients.
- The findings suggest that increasing the frequency of monitoring beyond every 90 days may not provide significant benefits, with tachyarrhythmia being the most common issue identified.
Article Abstract
Background: Heart Rhythm Society expert consensus provides recommendations for surveillance monitoring of cardiac implantable electronic devices (CIEDs), but limited data are available for the pediatric and congenital heart disease population.
Objective: The purpose of this study was to determine the rate of actionable events during CIED surveillance in this population, assess the utility of routine CIED remote monitoring, and assess the potential benefit from more frequent monitoring.
Methods: This was a retrospective cohort study of all CIED patients followed at a pediatric and congenital heart center and enrolled in the Medtronic Carelink system with either (1) a chronic (implanted for >6 months) CIED followed between July 1, 2010, and July 1, 2012, on a bimonthly schedule; or (2) a new CIED (implanted <6 months) between July 1, 2008, and July 1, 2012, followed on a monthly schedule.
Results: Aggregate mean age was 20 ± 13.7 years. There were 608 interrogations on newly implanted CIEDs with an actionable event rate of 11 per 100 patient-years. There were 2614 interrogations of chronic CIEDs with an actionable event rate of 22 per 100 patient-years. The odds of an actionable event on an asymptomatic remote monitoring transmission was lower than if symptomatic (odds ratio 0.04, 95% confidence interval 0.03-0.07). Tachyarrhythmia was the most common event. Predictors of actionable events were identified.
Conclusion: In this population of pediatric and congenital heart disease patients, the rate of actionable events was low, especially on asymptomatic interrogations. Most actionable events were due to tachyarrhythmia. A more frequent than every 90-day monitoring schedule does not appear to be of significant benefit.

Unlabelled: Unilateral absence of pulmonary artery (UAPA) is a rare and underdiagnosed entity. Due to its varied clinical expression, especially respiratory and most frequently associated with congenital heart disease, it can also present in isolation and remain asymptomatic for a long time. There is no consensus on its treatment, which is generally reserved for the presence of complications, mainly pulmonary hypertension, hemoptysis, or recurrent respiratory infections.

The C3PO collaborative, with a history of successful quality improvement (QI) initiatives, leveraged registry participants to develop a multi-center QI initiative to reduce adverse events (AEs) in congenital cardiac catheterization. A 32-person, interdisciplinary working group analyzed audited data for all congenital cardiac catheterization cases from 2014-2017. The primary outcome was the occurrence of any high-severity (level 3/4/5) AE.

Background: Three-dimensional rotational angiography (3DRA) is a promising advancement to guide cardiac catheterizations. It is used with restraint in critically ill infants with congenital heart disease (CHD) due to the lack of research conducted within this patient group.
Methods: Data of all infants with CHD and a body weight <5 kg who underwent cardiac catheterization with the use of 3DRA between November 2011 and April 2021 were retrospectively analyzed.
