FOR IMMEDIATE RELEASE

            ATS Medical Reports Strong Second Quarter Revenue Growth
       Total Revenue Increases 17% Year-Over-Year to New Quarterly Record
        Revenue from Diversification Strategy Increases Nearly Threefold
           Gross Margins Exceed 50% for First Time in Company History
                      Company Reiterates Guidance for 2006

MINNEAPOLIS, August 2, 2006 -- ATS Medical, Inc. (NASDAQ: ATSI) manufacturer and
marketer of state-of-the-art cardiac surgery products and services, today
reported the highest quarterly revenue in its history. Revenue for the second
quarter ended June 30, 2006 was $10.9 million, surpassing the previous record of
$9.9 million set in the fourth quarter of 2005. Revenue for the second quarter
increased 17% from the comparable period a year ago, and 12% from the first
quarter of 2006.

Revenue generated from products and services other than the Company's mechanical
heart valve increased nearly threefold from the second quarter of 2005 to $1.8
million and worldwide mechanical heart valve sales increased 4.3%. Revenue from
ATS Medical's newest products represented 16.4% of total revenue, up from 14.3%
in the first quarter of 2006.

Gross margins for the second quarter increased to 50.2% from 41.2% for the
comparable second quarter of 2005. The operating loss for the period ended June
30, 2006 was $2.4 versus $3.1 million for the second quarter ended June 30,
2005. The net loss for the quarter was $2.8 million, or $0.09 per share compared
with the net loss for the second quarter of 2005 of $3.1 million, or $0.10 per
share.




"The continued development of our product portfolio that focuses on the unique
needs of the cardiac surgery market led to a new record quarter," said Michael
Dale, Chairman, President & CEO. "Our team is executing well and, as a result,
we nearly tripled the sales of new products added to our portfolio during the
past 18 months to nearly $1.8 million. Sales of our CryoCath products for
surgical cryoablation of cardiac arrhythmias more than doubled compared with the
second quarter of 2005. Our second quarter performance underscores the cardiac
surgery community's continued embrace of our products and services, and
illustrates ATS Medical's emergence as a leading innovator and provider of
proprietary technology to the cardiovascular surgeon.

"Since we updated our shareholders on the proposed acquisition of 3F
Therapeutics, we've made further progress toward completing this transaction,"
continued Mr. Dale. "As expected, we have filed amendments to our latest Form
10-K and Form 10-Q with the Securities and Exchange Commission (SEC) reflecting
restated financials for 2005 and the first quarter of 2006, and we have filed an
amendment to our Form S-4 related to the 3F Therapeutics acquisition responding
to the SEC's last round of comments. Our goal remains to hold our shareholder
meeting and close this transaction during the third quarter."

Outlook
- -------
"Despite the tough competitive environment, we remain on track to achieve our
2006 financial goals and are reiterating our guidance," continued Mr. Dale. "We
continue to believe that for the full year we will increase sales by a minimum
of 20% and surpass $40 million in annual revenue. While the third quarter is
impacted by seasonality in both the U.S. and European markets, we do expect
gross margins for the second half of the year to continue to increase beyond the
second quarter's record level. We will continue to focus on 3F Therapeutics
product development programs as well as ATS development programs including the
PARSUS(TM) blood filtration technology and next-generation heart valve related
research. While we will generate a net loss for the year, we do believe we will
substantially improve the enterprise value of ATS Medical through the 3F
transaction as well as the continued execution of our strategy." Mr. Dale
concluded.
