(A) BAPN + surgery swine had significantly higher mean aortic dilation compared with non BAPN-treated (surgery alone) swine at 28 days (113.5± 30.2% (52.9–146.2%) vs. 59.7±29.2% (0–86.7%); p<0.01). (B) BAPN-treated swine showed mean aortic dilation of 86.9±47.4% (55.6–157.1%), 105.4±58.1% (50–133.3%), and 113.5±30.2% ( 52.9–146.2%) at 7, 14, and 28-day harvest timepoints, respectively;
