Background: Windsock deformities, though rare, represent a severe form of valvular aneurysm distinguished by localized balloon-like protrusions of the leaflet body. Here, we present a compelling case of windsock mitral valve (MV) formation subsequent to incompletely managed aortic valve (AV) endocarditis. The case is illustrated through radiographic, intraoperative, and histopathologic images.

Camera-trapping is effective for surveying terrestrial wildlife, but many species lack individually unique natural markings that are required for most abundance and density estimation methods. Analytical approaches have been developed for producing population estimates from camera-trap surveys of unmarked wildlife; however, most unmarked approaches have strict assumptions that can be cryptically violated by survey design characteristics, practitioner choice of input values, or species behavior and ecology.

Methods: Within the prospective, multicenter Genomic Research Alliance for Transplantation study, 181 proteins were evaluated from blood drawn at the time of endomyocardial biopsy; protein fold change, logistic regression, and pathway analyses were conducted, with protein discovery adjusted for a 5% false discovery rate.
Results: Among 104 adult heart transplant patients (31% female sex, 53% Black race, median age 52 y), 74 had no rejection, 18 developed acute cellular rejection (ACR), and 12 developed antibody-mediated rejection (AMR).
