Background: To determine if racial disparities exist between African Americans (AA) and Non-Hispanic Whites (NHW) for patients undergoing repair of acute type A aortic dissection (ATAAD) at a rural tertiary academic medical center.
Methods: There were 215 consecutive AA and NHW patients who underwent ATAAD repair at our institution from 1999 to 2019 included in a retrospective analysis of our Society of Thoracic Surgeons Adult Cardiac Surgery Database. Statistical analysis was performed with a p value of less than .
Background: The Society of Thoracic Surgeons current (STS) guidelines recommend delaying coronary artery bypass graft surgery (CABG) for several days or performing platelet function testing in stable patients who received P2Y12 inhibitors. Our program routinely uses thromboelastography-platelet mapping (TEG-PM) to expedite CABG in P2Y12 nonresponders. We hypothesize that P2Y12 nonresponders had no difference in length of stay to surgery and blood product transfusion compared with patients undergoing urgent inpatient CABG not treated with a P2Y12 inhibitor.

- The study examines the outcomes of open repair surgeries for descending thoracic aneurysm (DTA) and thoracoabdominal aortic aneurysm (TAAA) in patients aged 80 and older, comparing them to younger patients.
- Octogenarians faced various health challenges, such as chronic pulmonary disease and peripheral vascular disease, and more often had degenerative aneurysms compared to younger patients, but their operative mortality rate was similar (5.6% for both age groups).
- Overall, age was not a significant predictor of operative mortality or complications; octogenarians experienced a preferred surgical approach that resulted in shorter cross-clamp times.
Accessory mitral valve (AMV) is a rare congenital cardiac malformation associated with left ventricular outflow tract obstruction and endocarditis. We report a patient with an AMV who presented with a cerebellar infarct and discuss the management of this anomaly.

This study evaluated whether retrograde cerebral perfusion (RCP) provides adequate brain protection for prolonged periods of deep hypothermic circulatory arrest (DHCA).
Methods: From January 1997 to December 2014, 1,043 patients underwent aortic arch operations using RCP and DHCA at 18°C.
Cell-deposited matrix improves retinal pigment epithelium survival on aged submacular human Bruch's membrane.

Purpose: To determine whether resurfacing submacular human Bruch's membrane with a cell-deposited extracellular matrix (ECM) improves retinal pigment epithelial (RPE) survival.
Methods: Bovine corneal endothelial (BCE) cells were seeded onto the inner collagenous layer of submacular Bruch's membrane explants of human donor eyes to allow ECM deposition. Control explants from fellow eyes were cultured in medium only.
