FOR IMMEDIATE RELEASE

           ATS MEDICAL REPORTS 37.5% INCREASE IN FOURTH QUARTER SALES
               Fourth Quarter and Full Year Results Set New Record

MINNEAPOLIS, February 8, 2006 /PR Newswire-First Call/-- ATS Medical, Inc.
(Nasdaq: ATSI), developer, manufacturer and marketer of state-of-the-art cardiac
surgery products and services, today reported that sales for the fourth quarter
of 2005 increased 37.5% to $9.9 million, compared with sales of $7.2 million for
the fourth quarter of 2004. Mechanical heart valve sales represented 86% of
total revenue, while other products and services represented 14% of total
revenue. There was no meaningful impact on revenue from foreign currency
exchange. The operating loss for the fourth quarter of 2005 was $5.1 million,
compared with an operating loss of $5.5 million in the fourth quarter of 2004.
The net loss in both 2005 and 2004 for the fourth quarter was $5.4 million.

For the full year ended December 31, 2005, sales increased 24% to $34.6 million,
compared with sales of $28.0 million for the year ended December 31, 2004. The
net loss for the year was $16.6 million, which was comparable to the net loss of
$16.6 million for 2004.

"We finished 2005 with a record quarter and a strong foundation for success for
the future," said Michael Dale, Chairman, President and CEO. "We achieved sales
growth of 37.5% through an 18.3% year-over-year increase in the sales of our
Open Pivot Heart Valve(R) and a 15.3% sequential increase in the sale of other
products and services. The diversification of our product portfolio over the
last year into surgical ablation of cardiac arrhythmias, cardiac allograft
tissue services, and our entry this quarter into the heart valve repair market,
expand our market opportunities while leveraging existing customer relationships
and distribution infrastructure. Our proposed acquisition of 3F Therapeutics
potentially expands our revenue market opportunity by more than $600 million and
substantially completes our effort to establish a competitive presence in all
segments of




the $1.2 billion heart valve therapy market. Each of the three generations of
the 3F Aortic Bioprosthesis(TM) product line is unique in its advantages while
sharing a common technology platform. We believe 3F's tissue heart valve and
beating heart surgery technology will provide ATS a best of class product
offering capable of capturing tissue heart valve market share in the short- and
long-term.

"Finally, we continued to make operational progress during the fourth quarter
and are on target with our efforts to improve gross margins in 2006," said Mr.
Dale. "Our inventories have declined more than $6 million, or 22%, from the
December 31, 2004 level. During the fourth quarter of 2005, we charged $1.8
million of production variances related to our pyrolytic carbon manufacturing
activities to operations due to the completion of an analysis of the Company's
pyrolytic carbon facility and the determination that certain factory ramp-up
costs should be appropriately charged to cost of sales. Selling and marketing
costs for the fourth quarter of 2005 increased approximately 10% year-over-year
due primarily to the expansion of the product lines we offer the cardiovascular
surgeon, while general and administrative expense has increased 5% primarily due
to the expensing of restricted stock awards.

"Looking ahead, we believe we will increase sales in 2006 by at least 20% and
surpass $40 million in annual revenue," continued Mr. Dale. "The 3F research and
development program will substantially increase our investment in this area
during 2006. However, we do expect to continue to increase our gross margins as
we consume our remaining high-cost pyrolytic carbon inventory during the first
quarter of 2006. In addition, we remain very excited about the market potential
of the PARSUS(TM) blood filtration technology and look forward to reporting on
the next product development milestone in the first half of 2006," Mr. Dale
concluded.
