Propensity Score-Matched Analysis of Open Surgical and Endovascular Repair for Type B Aortic Dissection

<table>In-hospital mortality rates for emergently admitted TBAD patients undergoing TEVAR based on the annual hospital volume of TEVAR procedures performed. The following are the number of emergently admitted TBAD patients treated with endovascular repair in each TEVAR volume group: 1–4 (<i>n</i> = 225), 5–8 (<i>n</i> = 237), 9–14 (<i>n</i> = 217), 15–29 (<i>n</i> = 239), 30–55 (<i>n</i> = 241), greater than 55 (<i>n</i> = 167), less than 30 (<i>n</i> = 917), 30 or more (<i>n</i> = 408).</table>
