Should mitral valve replacement age guidelines be lowered due to better bioprosthetic mitral valve durability?

Objective: Guideline recommendations for mechanical or bioprosthetic valve for mitral valve replacement by age remains controversial. We sought to determine bovine pericardial valve durability by age and risk of reintervention.

Methods: This retrospective study between 2 large university-based cardiac surgery programs examined patients who underwent bioprosthetic mitral valve replacement from 2004 to 2020.

Late results of chord transfer and other techniques for anterior leaflet repair without neochords.

Objective: Anterior and bileaflet degenerative mitral regurgitation repairs are challenging. We examined our early and late outcomes for repair using 4 techniques, without neochord repair.

Methods: Between February 1, 2006, and June 30, 2021, a total of 2368 patients received mitral valve ± other surgery by 1 surgeon, including 1160 with degenerative mitral regurgitation.

Bridging the gap: A library-based collaboration to enhance data skills for clinical researchers.

Introduction: Enterprise data warehouses (EDWs) serve as foundational infrastructure in a modern learning health system, housing clinical and other system-wide data and making it available for research, strategic, and quality improvement purposes. Building on a longstanding partnership between Northwestern University's Galter Health Sciences Library and the Northwestern Medicine Enterprise Data Warehouse (NMEDW), an end-to-end clinical research data management (cRDM) program was created to enhance clinical data workforce capacity and further expand related library-based services for the campus.

Methods: The training program covers topics such as clinical database architecture, clinical coding standards, and translation of research questions into queries for proper data extraction.

Veno-Venous Extracorporeal Rewarming Using Dual-Lumen Cannula in Accidental Hypothermia.

Accidental hypothermia with a core temperature below 28°C is associated with an increased risk of hemodynamic instability. It is difficult to predict which patients will survive with a favorable neurologic outcome; therefore, decision-making regarding extracorporeal support is not straightforward. We report a case of rewarming using veno-venous dual-lumen cannula as an alternative to veno-arterial support with full recovery and normal neurologic examination.

A multiparameter algorithm to guide repair of degenerative mitral regurgitation.

Purpose: Degenerative mitral regurgitation repair using a measured algorithm could increase the precision and reproducibility of repair outcomes.

Methods: Direct and echocardiographic measurements guide the repair to achieve a coaptation length of 5 to 10 mm and minimize the risk of systolic anterior motion. Leaflet reconstruction restored the normal 2 to 1 ratio of anterior to posterior leaflet length without residual prolapse or restriction.

Concurrent Proximal Fractures Are Rare in Distal Forearm Fractures: A National Cross-sectional Study.

Introduction: Distal forearm fractures (DFF) account for 1.5% of emergency department (ED) visits in the United States. Clinicians frequently obtain imaging above/below the location of injury to rule out additional injuries.
