Background: The Pediatric Interagency Registry for Mechanical Circulatory Support (Pedimacs), supported by The Society of Thoracic Surgeons, provides detailed information on pediatric patients supported with ventricular assist devices (VADs).
Methods: From September 19, 2012, to December 31, 2023, there were 1648 devices in 1349 patients (<19 years) from 39 North American Hospitals with 100 patients enrolled in 2023.
Results: Cardiomyopathy was the most common underlying etiology (59%), followed by congenital heart disease (26%) and myocarditis (8%).
Background: The use of the Ostial Flash balloon (Ostial Corporation) has received limited study in aorto-ostial chronic total occlusion (CTO) percutaneous coronary artery intervention (PCI).
Methods: The authors evaluated the outcomes of Ostial Flash balloon use in a large CTO-PCI registry (PROGRESS-CTO, NCT02061436).
Results: The Ostial Flash balloon was used in 54 of 907 aorto-ostial CTO PCIs in 905 patients (6.
The Melody Valve in Small Children Undergoing First Mitral Valve Replacement: Better Than Mechanical?
Ann Thorac Surg Short Rep
September 2024
Background: In small children with left atrioventricular valve dysfunction, valve repair is preferred but some will require valve replacement. No prosthetic valve has growth potential, bioprostheses have poor durability, and mechanical prostheses have high rates of thromboembolic and hemorrhagic complications. We reviewed our experience with a modified bovine jugular vein valve designed for use in the right ventricular outflow tract (Melody valve, Medtronic) and compared this with contemporary mechanical valve replacement.

Current diagnosis emphasizes the detection of left ventricular hypertrophy (LVH) using a fixed threshold of ≥15-mm maximum wall thickness (MWT). This study proposes a method that considers individual demographics to adjust LVH thresholds as an alternative to a 1-size-fits-all approach.

- Interest in how plant-based diets affect the gut microbiome is increasing, but there's limited research on how different diet patterns (omnivore, vegetarian, vegan) impact microbiome profiles across various populations.
- A study involving over 21,000 individuals found that gut microbiome profiles can effectively differentiate between these diet patterns, with a mean accuracy of 85%.
- Key findings show that omnivore microbiomes are heavily influenced by red meat consumption, which is linked to negative health markers, while vegan microbiomes are associated with healthier outcomes and overlap with specific food and soil microbes.
