NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

March 31, 2002


Note A - BASIS OF PRESENTATION

The accompanying unaudited financial statements have been prepared in accordance
with generally accepted accounting principles for interim financial information
and with the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation have been included.
Operating results for the three months ended March 31, 2002 are not necessarily
indicative of the results that may be expected for the year ending December 31,
2002. In our Form 10-K filed with the Securities and Exchange Commission for the
year ended December 31, 2001, we identified critical accounting policies and
estimates for our business.












ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS


We manufacture and market a mechanical bileaflet heart valve with a patented
pivot design. Our heart valve is used to treat valvular heart disease caused by
the natural aging process, rheumatic heart disease and congenital defects. We
have received regulatory approvals to market the ATS heart valve in the United
States and most international markets, principally Europe, Japan, Canada and
Australia.

We commenced selling the ATS heart valve in international markets in 1992. We
sell the valve to independent distributors with assigned territories (generally
a specific country or region) who in turn sell the valve to hospitals or
clinics. Most of our sales to international distributors are denominated in U.S.
dollars so currency risk is borne by the distributor; however, as the dollar
increases in value relative to the distributor's local currency, the cost of the
valve increases for the distributor even though ATS does not change the selling
price. This has caused us to adjust the selling price to the affected
distributors to help offset a portion of the currency loss. During 2001 we hired
a direct sales force and began selling the ATS heart valve in the United States.
As a result of these efforts, our U.S. sales as a percentage of our overall
sales increased from 4% in 2000 to 17% in 2001 and 2002.

We currently purchase all of the pyrolytic carbon components for the ATS heart
valve from Sulzer Carbomedics, Inc. (Carbomedics) pursuant to a multi-year
supply agreement entered into in 1990. The cost of the pyrolytic carbon
components represents approximately 80% of the total cost of the ATS heart
valve. Under the supply agreement with Carbomedics, the cost of the pyrolytic
carbon components has varied according to annual volume purchases and is
adjusted annually by reference to increases in the U.S. Department of Labor
Employment Cost Index. In December 1999, we renegotiated the supply agreement
with Carbomedics. The supply agreement, as amended, provides for significant
reductions in our minimum purchase requirements and unit costs beginning in
2001. In December 2000 we again amended the supply agreement to purchase
additional valves in 2001 and eliminate the minimum units for 2007. We are
obligated to purchase pyrolytic carbon components from Carbomedics through 2006
and the Supply Agreement runs through 2007. In addition, under a new carbon
agreement, Carbomedics has granted us an exclusive right to use its carbon
coating technology to manufacture pyrolytic carbon components for the ATS heart
valve. Carbomedics also has agreed to assist us in establishing our own
pyrolytic carbon component manufacturing facility. In return, we have agreed to
pay a license fee totaling $41 million over seven years, $13 million of which
has been paid as of March 31, 2002.

Results of Operations

Net sales for the quarter ended March 31, 2002 decreased 8% to $3,902,263
compared to $4,253,573 for the quarter ended March 31, 2001. The decrease from
last year's first quarter was primarily due to lower selling prices in several
international markets. Unit sales for the quarter ended March 31, 2002 decreased
4% compared to unit sales for the quarter ended March 31, 2001. Revenue in the







United States increased 66% in the quarter ended March 31, 2002 compared to the
quarter ended March 31, 2001, but decreased 18% compared to the quarter ended
December 31, 2001. Non-U.S. revenue in the quarter ended March 31, 2002
decreased 16% compared to the quarter ended March 31, 2001, but increased 75%
compared to the quarter ended December 31, 2001. Net sales in Europe were
essentially flat for the quarter ended March 31, 2002 compared to the quarter
ended March 31, 2001, however unit sales in Europe increased 14% for the quarter
ended March 31, 2002 compared to the quarter ended March 31, 2001. In the face
of continued weakness of the Euro relative to the U.S. dollar and price-cutting
by our competitors, we have reduced our selling prices in several European
markets.

In the U.S. market, ATS reports the selling price to the hospital. In non-U.S.
markets, ATS reports the selling price to the distributor. As U.S. sales
increase as a percentage of overall sales, the overall average selling price may
increase, even though the average selling prices in some non-U.S. markets may be
steady or declining. Hospital administrators continue to apply pressure for
lower prices, and the willingness of competitors to reduce prices will continue
to put pressure on revenue growth and margins.

In the United States, we have established a direct sales force to sell the
valve. Valves are consigned to hospitals desiring to use the ATS valve and a
sale is recorded once the valve is implanted. We had 12 sales people and four
regional managers located in the United States at March 31, 2002. The launch of
a product of critical importance to patients such as a heart valve is an ongoing
process. The "sales cycle" for new accounts can take from one to three months.
We feel that we have a superior product, however, our competitors have larger
sales staffs and greater financial resources so they are currently able to reach
more potential customers. The rate at which we open new accounts and realize new
implants is difficult to forecast from quarter to quarter.

Cost of sales for the three months ended March 31, 2002 totaled $2,690,911 or
69% of sales compared to $2,608,160 or 61% of sales for the three months ended
March 31, 2001. ATS uses the first-in first-out ("FIFO") method of accounting
for inventory. All of our valves sold in the first quarter of 2002 were made
with carbon purchased in 1999 (under FIFO). A significant portion of our
inventory is made up of finished goods and we also had workforce reductions in
September and November 2001. As a result, production (assembly) is at only a
fraction of capacity and in the first quarter 2002. Overhead cost variances
relating to such reduced level of production and approximating 4% of sales were
charged to cost of goods sold. Until sales increase substantially, we expect the
level of assembly to be insufficient to absorb all of our manufacturing overhead
costs.

Gross profit totaled $1,211,352 for the quarter ended March 31, 2002 or 31% of
sales, compared to gross profit of $1,645,413 or 39% of sales for the quarter
ended March 31, 2001. The average selling price per unit decreased in the first
three months of 2002 compared to the first three months of 2001 by about 4%. The
average cost per unit sold decreased slightly but not enough to increase gross
profit even before taking into account the overhead variances.

Research, development and engineering expenses totaled $925,659 for the quarter
ended March 31, 2002 versus $757,914 for the quarter ended March 31, 2001, an
increase of 22%. In the quarter ended March 31, 2001, we were still installing







equipment, and had eight people on the project. In the quarter ended March 31,
2002, we had 17 people on the project. Approximately 78% of research and
development expenses for the quarter ended March 31, 2002 were related to our
own carbon manufacturing facility. Our focus during 2001 and the first quarter
of 2002 was making qualification and verification coating runs, training ATS
personnel on the new carbon manufacturing equipment installed during the period,
and documenting procedures. This culminated with the submissions at the end of
the first quarter 2002 to the T.U.V., who we use as a notified body for our
European approval, and the U.S. Food and Drug Administration.

Sales and marketing expenses increased as expected in the quarter ended March
31, 2002 to $1,158,932 compared to $1,067,712 in the quarter ended March 31,
2001. We hired U.S. salespeople during the first quarter 2001 and went from
eight salespeople and three regional managers at December 31, 2000 to 15
salespeople and four regional managers employed at March 31, 2001. At March 31,
2002 we had 12 salespeople and four regional managers. The 9% increase in sales
and marketing expense in the quarter ended March 31, 2002 compared to the
quarter ended March 31, 2001 was due to having the salespeople employed for the
entire quarter and increased marketing expenses.

General and administrative expenses totaled $674,243 for the three months ended
March 31, 2002, a decrease from the $815,678 reported for the three months ended
March 31, 2001. We had 81 employees at March 31, 2002 compared to 120 employees
at March 31, 2001. The Company had work force reductions that started in
September 2001 and to date have resulted in the layoff of 48 people.

Interest income totaled $64,111 for the quarter ended March 31, 2002 compared to
$420,574 for the quarter ended March 31, 2001. The decrease in interest income
in the first quarter of 2002 was the result of lower average investable cash
balances during the first quarter of 2002 and lower interest rates.

ATS recorded a net loss of $1,483,371 or ($0.07) per share for the quarter ended
March 31, 2002 compared to a net loss of $575,317 or ($0.03) per share for the
quarter ended March 31, 2001. The decreases in gross margin and interest income,
coupled with the 4.4% increase in expenses, were the reasons for the increased
loss. We are working to increase sales, particularly in the United States, in
order to return to profitability in future quarters. Sales will have to
approximately double in order to report positive operating income.

ATS has accumulated approximately $22 million of net operating loss
carryforwards for U.S. tax purposes. ATS believes that its ability to fully
utilize the existing net operating loss carryforwards could be restricted on a
portion of the NOL for changes in control occurring in prior years. We do not
accrue any tax benefits for such losses.

LIQUIDITY AND CAPITAL RESOURCES

Cash, cash equivalents and short-term investments decreased by $1,947,322 from
$12,277,040 at December 31, 2001 to $10,829,718 at March 31, 2002. ATS will
continue to use more cash than it generates from operations in 2002, as it
expands its direct sales force, purchases carbon components from Carbomedics and
makes the carbon technology milestone payment in December 2002 to Carbomedics.







ATS has contracted to purchase $8.4 million of components during 2002 in
accordance with the terms of its amended long-term supply agreement with
Carbomedics (the "Supply Agreement"). These purchases are not tied to sales of
the ATS valve, and we do not expect sales of the valve to exceed the minimum
purchase requirements under the Supply Agreement in 2002.

In December 1999, ATS renegotiated its Supply Agreement with Carbomedics. The
Supply Agreement, as amended, provides for significant reductions in our minimum
purchase requirements and unit costs for the years 2001 through 2006. ATS
estimates that its minimum purchase requirements under the Supply Agreement from
2003 through 2006 will total approximately $18 million. Under the new carbon
agreement entered into in December 1999, ATS agreed to pay Carbomedics a license
fee of $41 million in installments over the next seven years. In addition to
granting ATS an exclusive worldwide right and license to use its carbon coating
technology to manufacture pyrolytic carbon components for the valve under this
agreement, Carbomedics agreed to assist ATS in designing, building and
commencing operations in its own pyrolytic carbon production facility in
Minneapolis, Minnesota.

Accounts receivable increased from $4,082,992 at December 31, 2001 to $4,944,000
at March 31, 2002, as sales increased from $2,666,904 in the fourth quarter,
2001 to $3,902,263 in the first quarter, 2002.

Current liabilities have remained constant at approximately $2.7 million between
December 31, 2001 and March 31, 2002, as well as the preceding last three
quarters.

Based upon the current forecast rate of 2002 sales, the anticipated purchase
obligations under the Supply Agreement, the license fee payments under the
carbon agreement, the expenses associated with establishing a direct sales force
in the United States and other expected expenses, ATS anticipates that cash and
marketable securities on hand at March 31, 2002 should meet its requirements
through 2002. Our minimum purchase commitment for carbon components in 2003 will
be approximately one half of our 2002 minimum purchase commitment. However, we
must achieve a significant rate of increase in U.S. valve sales, and reverse the
decline in European sales experienced in 2001 or we will need to raise
additional capital in the future. In addition, as identified in our cautionary
statement below, any adverse change that affects our access to the capital
markets, the construction of our carbon facility, or future demand for our
products will affect our longer term liquidity. Maintaining adequate levels of
working capital depends in part upon the success of our products in the
marketplace, the relative profitability of those products and our ability to
control operating and capital expenses. Funding of our operations in future
periods may require additional investments in ATS in the form of equity or debt.
There can be no assurance that we will achieve desired levels of sales or
profitability, or that future capital infusions will be available.







THE SINGLE EUROPEAN CURRENCY

A significant portion of our sales occur in Europe. We sell to all of our
customers in U.S. dollars. Our selling prices are similar to those of most of
our European distributors and therefore should not cause significant disruption
whether in U.S. dollars or Euros. From its introduction in January 1999, the
rate of exchange for the Euro versus the U.S. dollar declined by as much as 34%.
Several of our European distributors were unable to increase their local
currency selling price for the valve, and, as a result, they informed us that
their profits were being significantly reduced and we adjusted our pricing to
give them some relief. Europe is a very important market for us. Disruption or
loss of a portion of the European business could have a material and adverse
impact on our financial position.

CAUTIONARY STATEMENT PURSUANT TO THE PRIVATE SECURITIES LITIGATION REFORM ACT OF
1995

The Private Securities Litigation Reform Act of 1995 (the "Act") provides a
"safe harbor" for forward-looking statements to encourage companies to provide
prospective information about their business, so long as those statements are
identified as forward-looking and are accompanied by meaningful cautionary
statements identifying important factors that could cause actual results to
differ materially from those discussed in the statement. ATS desires to take
advantage of the safe harbor provisions with respect to any forward-looking
statements it may make in this filing, other filings with the Securities and
Exchange Commission and any public oral statements or written releases. The
words or phrases "will likely," "is expected," "will continue," "is
anticipated," "estimate," "projected," "forecast," or similar expressions are
intended to identify forward-looking statements within the meaning of the Act.
Such statements are subject to certain risks and uncertainties that could cause
actual results to differ materially from those projected. ATS cautions readers
not to place undue reliance on any such forward-looking statements, which speak
only as of the date made.

In accordance with the Act, ATS identifies the following important general
factors which if altered from the current status could cause our actual results
to differ from those described in any forward-looking statements: the continued
acceptance of our mechanical heart valve in international markets, the rate of
increase of acceptance of the valve in the United States, our ability to
recruit, hire and manage a direct sales force in the United States, the
continued performance of our mechanical heart valve without structural failure,
the actions of our competitors including pricing changes and new product
introductions, the continued performance of our independent distributors in
selling the valve, the risk of product returns in connection with distributor
terminations, the actions of our supplier of pyrolytic carbon components for the
valve and difficulties we may encounter establishing and operating our own
pyrolytic carbon manufacturing capability. This list is not exhaustive, and we
may supplement this list in filings with the Securities and Exchange Commission
(including Exhibit 99.1 to this Form 10-Q) or in connection with the making of
any specific forward-looking statement.









ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of our investment activities is to preserve principal
while at the same time maximizing the income we receive from our investments
without significantly increasing risk. Some of the securities in which we invest
may have market risk. This means that a change in prevailing interest rates may
cause the fair market value of the principal amount of the investment to
fluctuate. For example, if we hold a security that was issued with a fixed
interest rate at the then-prevailing rate and the prevailing interest rate later
rises, the fair value of the principal amount of our investment will probably
decline. To minimize this risk we maintain our portfolio of cash equivalents and
short-term investments in a variety of securities, including commercial paper,
money market funds, government and non-government debt securities. The average
duration of all of our investments has generally been less than one year. Due to
the short-term nature of these investments, we believe we have no material
exposure to interest rate risk arising from our investments.

We do not use derivatives and, therefore, do not face market risk from currency
or interest rate changes on these types of instruments. If we were required to
finance future operations with debt, we would have exposure to increases in
interest rates or borrowings.
