Transcatheter aortic valve replacement (TAVR) was FDA approved for the Sapien valve (Edwards Lifesciences) in the United States in November 2011. We sought to examine the impact of TAVR post-FDA approval on aortic valve surgery at our institution. ⋯ Since initiation of the TAVR program at our institution, the total number of aortic valve procedures has increased. Transcatheter aortic valve replacement patients had more preoperative comorbidities, but no difference in postoperative morbidity or mortality and shorter length of stay. Transcatheter aortic valve replacement mortality has continued to improve since the inception of the program.

Level 1 data demonstrate that adjuvant chemotherapy (ACT) improves survival after surgical resection of pancreatic ductal adenocarcinoma (PDAC), (adjuvant gemcitabine, CONKO-001 study; adjuvant 5-FU, ESPAC3 study). The role of adjuvant chemoradiation therapy (ACRT) remains controversial. What is less clear is whether adjuvant therapy influences patterns of recurrence. The purpose of this study was to perform the first multicenter study analyzing patterns of recurrence after adjuvant therapy for PDAC. ⋯ This is the first analysis demonstrating differences in recurrence patterns in PDAC patients based on type of adjuvant therapy. Adjuvant chemotherapy provided an OS advantage likely related to its effect on reducing both LR and DR. Adjuvant chemoradiation therapy appears to decrease LR, but not DR, and therefore has less impact on OS. Future investigations and treatment protocols should consider additional ACT rather than ACRT in the treatment of PDAC.
