FOR IMMEDIATE RELEASE


ATS MEDICAL REPORTS 41 PERCENT REVENUE GROWTH IN THIRD QUARTER

                               o US SALES UP 38%
                          o INTERNATIONAL SALES UP 43%
               o CONFERENCE CALL SCHEDULED FOR TODAY AT 5 PM EDT


MINNEAPOLIS, October 27, 2004 -- ATS Medical, Inc. (NASDAQ: ATSI) developer and
manufacturer of the ATS Open Pivot(R) mechanical heart valve and related cardiac
surgical accessories and technologies today reported that revenue for the third
quarter of 2004 increased 41 percent to $6.5 million, compared to sales of $4.6
million for the third quarter of 2003. The net loss for the third quarter of
2004 was $4.5 million and was impacted by approximately $400,000 in factory
production ramp up costs recognized as cost of goods sold. The third quarter
2003 net loss was $307,000, which was benefited by a $2.6 million gain on
extinguishment of debt.

For the first nine months of 2004, revenue increased 62 percent to $20.8
million, as compared to $12.9 million for 2003. Net loss for the first nine
months of 2004 was $11.2 million compared with $4.9 million for 2003.

Michael D. Dale, President and CEO of ATS Medical commented, "We are pleased
with our continued progress in all markets. In the U.S. market we grew sales 38
percent compared to the third quarter of 2003 to $2.0 million. We sold to more
open heart centers during the quarter than in any other quarter of our company's
history. In international markets, we grew sales 43 percent to $4.5 million.

"Worldwide, we now estimate that our procedure share of the mechanical heart
valve market to be more than 13%, and that our growing open heart surgery center
presence is fast becoming the cardiac surgery business platform we set out to
build two years ago. We look forward to leveraging this platform in the coming
year."







Mr. Dale continued, "The production ramp-up at our carbon facility remains on
schedule and most of our work force at the facility has now been hired. We
expect training in large part to be completed by the end of the fourth quarter.
We continue to believe that we will realize significant cost savings by
manufacturing our own pyrolytic carbon components. These lower manufacturing
costs represent a primary factor behind our predicted profitability in 2006.

"Looking ahead to the remainder of 2004, we continue to expect total sales for
the year to be at least $28 million, a growth rate of more than 50 percent over
2003. Our initial estimate for 2005 will be to grow revenue by at least 20 to 25
percent versus 2004." concluded Mr. Dale.
