Pay vs Performance [Table Text Block] |  | Pay Versus Performance Disclosure The following table sets forth a comparison of compensation reported in the summary compensation table to compensation actually paid to our Principal Executive Officer (PEO) and other Named Executive Officers (NEOs) as well as information on our Company performance.
Year | Summary Compensation Table Total for PEO | Compensation Actually Paid to PEO | Average Summary Compensation Table Total for non-PEO NEOs | Average Compensation Actually Paid to non-PEO NEOs | Value of initial fixed $100 Investment based on: | Net Loss ($mm) | AORT Revenue Growth

| (a) | (a) | (b) | (b) | (c) | (c) | ​ | (d)

2020 | $3,415,458 | $327,652 | $977,089 | $454,525 | $87 | $140 | ($17) | -8.1%
(a) |  | Mr. Mackin served as our only PEO for each year.
(b) |  | Our Non-PEO NEOs in 2022 and 2021 were Messrs. Lee, Davis, Stanton and Ms. Holloway. Our Non-PEO NEOs in 2020 were Messrs. Lee, Davis, Simpson and Ms. Holloway. Mr. Stanton joined the company in March 2021.
(c) |  | Shareholder returns reflect $100 invested as of market close on December 31, 2019, the final trading day of fiscal 2019; Index Shareholder Return reflects NASDAQ Medical Equipment Index.
(d) |  | Company selected measure of revenue growth is used in incentive plans. Result is measured in constant currency and adjusted to appropriately reflect baseline. For 2022, the incentive plan measure for constant currency revenue growth was adjusted to exclude PerClot sales in 2021 and 2022. For 2021, the incentive plan measure for revenue growth reflected the 2nd half in 2021 as compared to the 2nd half in 2019. For 2020, revenue, as opposed to revenue growth, was used as a metric in the Company’s annual cash bonus plan, but due to the impact of COVID-19 on the Company’s business, the revenue result (along with adjusted net income which was also used that year as a metric) would have resulted in no payout under the cash bonus program. Accordingly, the payout under the cash bonus program for 2020 was based on executive officer performance to other goals as set forth in the Company’s 2021 Proxy Statement.
The following table sets forth a reconciliation from the Summary Compensation Table (“SCT”) to Compensation Actually Paid (“CAP”) to our PEO and for the average paid to our Non-PEO NEOs for the years ended December 31, 2020, 2021, and 2022.

Compensation Actually Paid vs. Total Shareholder Return [Text Block] |  | Because a majority of total compensation provided to the PEO and the average paid to the Non-PEO NEOs is via equity-based grants that vest over multi-year periods, the primary driver of changes in “Compensation Actually Paid” totals for the PEO and the average for the Non-PEO NEOs is the change in the Company’s stock price. |  |
Compensation Actually Paid vs. Company Selected Measure [Text Block] |  | As discussed in other sections of this proxy statement, in November 2022, the Compensation Committee decided to accelerate equity grants to officers that otherwise were expected to be made in the first quarter of 2023. The grant date and year-end 2022 fair values of these November 2022 grants have a significant impact on both the Summary Compensation Total and Compensation Actually Paid. The chart below shows 2022 Officer Compensation (SCT and CAP values) both as reported and excluding the impact of equity grants made in November 2022. |  |
Tabular List [Table Text Block] |  | Most Important Financial Measures Related To 2022 Officer Compensation As discussed in the CD&A, the annual short-term incentive plan used revenue growth (constant currency) as the primary financial measure for 2022. Annual PSUs granted during 2022 were earned based on revenue growth (constant currency) and adjusted EBITDA. LTIP shares earned during 2022 were based on revenue growth (constant currency) and, with respect to the 2019 LTIP, gross margin.
