Impella versus Non-Impella for Non-emergent High-Risk Percutaneous Coronary Intervention: Impella vs. Non-Impella for HR-PCI.

Background: The benefit of mechanical circulatory support (MCS) with Impella (Abiomed, Inc, Danvers, MA) for patients undergoing non-emergent, high-risk percutaneous coronary intervention (HR-PCI) is unclear and currently the subject of a large randomized clinical trial (RCT), PROTECT IV. While contemporary registry data from PROTECT III demonstrated improvement of outcomes with Impella when compared with historical data (PROTECT II), there is lack of direct comparison to the HR-PCI cohort that did not receive Impella support.

Methods: We retrospectively identified patients from our institution meeting PROTECT III inclusion criteria (left ventricular ejection fraction [LVEF] <35% with unprotected left main or last remaining vessel or LVEF <30% undergoing multivessel PCI), and compared this group (NonIMP) to the published outcomes data from the PROTECT III registry (IMP).

Outcomes of Concentrated Bone Marrow Aspirate with Extracellular Matrix in Pediatric and Adolescent Patients with Capitellar Osteochondritis Dissecans.

Background: Humeral capitellar osteochondritis dissecans (OCD) lesions can be challenging to treat. Past studies have demonstrated grafting with extracellular matrix with bone marrow aspirate concentrate (ECM-BMAC) to be a viable technique for treatment of talar dome OCD, though little literature exists regarding application of this technique to the capitellum. This study aimed to report patient-reported outcomes (PROs) and return to sport (RTS) of pediatric patients at ≥1-year postoperatively who underwent ECM-BMAC grafting for capitellar OCD lesions.

Opioid Consumption Following Isolated and Recurrent Shoulder Dislocation and Reduction.

Background: Recurrent shoulder dislocations often lead to multiple encounters for reduction and eventual surgical stabilization, both of which involve exposure to opioids and potentially increase the risk of chronic opioid exposure. The purpose of our study was to characterize shoulder instability and compare pre- and post-reduction opioid usage in singular dislocators (SD) and recurrent dislocators (RD).

Methods: This retrospective study was performed at a single academic institution using a prospective database.
