Comparison of pediatric VAD infection rates by device type: implanted, durable external, and temporary external.

Prevalence and Risk Factors for Ventricular Assist Device-Associated Infection in Children: An Analysis ACTION Study

About one in ten children supported by a ventricular assist device developed a device-associated infection, and one-year survival was no different for those who did. Drawing on 1,527 patients in the ACTION registry, the study found that implanted devices carried a proportionately higher infection rate than external ones.

RVAD timing in pediatric BiVAD support

Does Earlier Right Ventricular Assist Device Implant Confer a Survival Advantage

Concerns about survival have made biventricular support less common in children. Drawing on 223 pediatric patients in the ACTION registry, this study asked whether the timing of RVAD placement matters. Patients who received both devices in a single operation had better one-year survival, despite being sicker going into surgery.

Bridge to Candidacy VAD Patients

Clinical Outcomes and Complications in Pediatric Ventricular Assist Devices Implanted as Bridge to Candidacy

In this ACTION registry analysis of pediatric VAD recipients, patients bridged to transplant candidacy (rather than already listed at implant) faced significantly higher rates of major adverse events, on-device mortality, and lower rates of successful transplantation compared to bridge-to-transplant patients.

Double Bridge to Heart Transplantation: Outcomes of Early vs Delayed Extra Corporeal Membrane Oxygenator Crossover in Pediatric Population

This study evaluates the progression of the distal aorta in patients with acute type A aortic dissection complicated by malperfusion syndrome who were treated with endovascular fenestration/stenting followed by delayed open aortic repair, finding that although these patients had faster distal aortic growth, their long-term survival and reoperation rates were similar to those without malperfusion syndrome.

Dystrophinopathy in ACTION: The first 500 males enrolled in the Advanced Cardiac Therapies Improving Outcomes Network prospective dystrophinopathy registry

Early data from 500 males in the ACTION dystrophinopathy registry show substantial cardiac involvement and broad use of cardioprotective therapies. Ongoing follow-up will define the modern natural history of cardiomyopathy in dystrophinopathy.

Cardiac Medication Use in ACTION for Duchenne Muscular Dystrophy Cardiomyopathy

In a prospective study of 265 males with Duchenne Muscular Dystrophy, nearly 30% of those with moderate or severe heart dysfunction were not receiving full consensus-directed cardiac therapy, and most did not reach target medication doses—highlighting the need to optimize treatment strategies as cardiac disease becomes a leading cause of death in DMD.
