PLC SYSTEMS REPORTS FOURTH CONSECUTIVE PROFITABLE QUARTER

Company’s U.S. HL2 Laser Base Increases By 60 Percent From a Year Ago

Franklin, MA, April 30, 2003 – PLC Systems Inc. (AMEX: PLC), the worldwide leader in carbon dioxide (CO₂) transmyocardial revascularization (TMR) technology used to treat patients with severe angina, or heart pain, today reported positive financial results for the three months ended March 31, 2003.

First quarter net income increased by $274,000 to $15,000, or $0.00 per share, compared to a net loss of $259,000, or ($0.01) per share, for the first quarter ended March 31, 2002. Revenues for the quarter ended March 31, 2003 were $1,734,000, compared with $2,420,000 in the same quarter of 2002.

“We are very pleased to report PLC’s fourth consecutive quarterly profit,” stated Mark R. Tauscher, president and CEO of PLC Systems. “PLC’s first quarter performance demonstrates that our business can produce profitable results with a reasonable number and mix of lasers and kits sold. The four consecutive profitable quarters is a good reflection of our focused business strategy and our efficient operations at PLC. Expanding our laser base while maintaining profitability is a significant accomplishment for the company.”

During the first quarter of 2003, PLC shipped nine next-generation CO₂ Heart Lasers (HL2) to United States hospitals through Edwards Lifesciences Corporation (NYSE: EW), PLC’s exclusive U.S. sales and marketing partner. Five of the nine HL2 shipments were new lasers and four were redeployed lasers.

PLC ended the first quarter of 2003 with 138 CO₂ Heart Lasers located at heart centers throughout the U.S., comprised of 83 HL2 customers and 55 HL1 customers. As of March 31, 2003, PLC’s U.S. laser base (HL1 and HL2) had increased by more than 20 percent during the preceding twelve months. More significantly, PLC’s U.S. HL2 installed base grew to 83 lasers as of March 31, 2003, up 60 percent from March 31, 2002 and up nine percent from the quarter ended December 31, 2002.

A leading indicator for the adoption rate of the CO₂ TMR therapy is disposable kit shipments to hospitals. During the first quarter of 2003, a total of 413 disposable kits were shipped worldwide. Edwards delivered 383 disposable kits to United States hospitals and PLC shipped 30 disposable kits to International hospitals. In comparison, a total of 399 disposable kits were delivered worldwide during the quarter ended March 31, 2002.

Tauscher concluded, “With respect to kit shipments, I believe we are seeing positive signs that we are moving in the right direction. During 2002, the U.S. average kit shipments to hospitals by Edwards were 117 kits per month. In January and February 2003, this average was maintained, however during March and April the kit shipments have increased by approximately 50 percent. We are encouraged with this positive developing trend.”
