Internationally, the company posted 23% reported growth, with Europe up 33% and Asia Pacific and other regions advancing 12%.
Volume, not price, was the primary growth driver in pain management, as CryoSphere Plus and Max probes saw rapid adoption without a lift in average selling price. Gross margin remained stable, though slightly compressed by less favorable product and geographic mix. Operating expenses rose in line with global expansion and R&D investment, particularly for the LEAPS clinical trial and new product development. Adjusted EBITDA increased sharply year-over-year, and AtriCure generated positive cash flow for the second consecutive quarter, underscoring improved profitability and capital discipline.
- Product Innovation Drives Adoption: New launches in both pain and appendage management segments directly correlated with account expansion and procedure volume.
- International Momentum Sustained: CE mark expansions and new approvals in China and Europe extended the global growth runway.
- Hybrid AF Therapy Faces Headwinds: Broader PFA adoption pressured minimally invasive segment growth, but leadership expects longer-term patient funnel expansion.
Cash strength and operational leverage are enabling AtriCure to self-fund strategic bets, including a $12 million R&D charge for pulsed field ablation (PFA) technology integration, without derailing its positive cash flow trajectory.

Strategic Positioning
1. Pain Management Franchise Reacceleration
Rapid adoption of CryoSphere Plus and Max probes has re-energized the pain management business, with volume-led growth and positive clinical evidence supporting broader use. Clinical data presented at the AATS Summit demonstrated shorter hospital stays, reduced opioid usage, and significant cost savings, strengthening the value proposition for hospital systems and payers. The ongoing expansion into new procedural applications and geographies positions this segment for sustained momentum.
2. Open Ablation and Appendage Management Leadership
The Encompass clamp and AtriClip Flex Mini launches have driven meaningful share gains in both U.S. and international markets. The company is leveraging a strong installed base, clinical guidelines, and robust evidence (including 85 peer-reviewed studies on AtriClip) to defend and expand its leadership position. The recent CE mark expansion and China approval open new growth avenues, while the LEAPS trial could triple the addressable market if successful.
3. PFA Technology Integration and Portfolio Diversification
The exclusive partnership and development push into pulsed field ablation (PFA) mark a strategic pivot to ensure AtriCure’s portfolio remains relevant as the AFib treatment paradigm evolves. Leadership is clear that PFA will complement, not replace, existing RF and cryo modalities, offering physicians a full spectrum of ablation choices. The company expects to provide more details and clinical milestones in 2025, with initial focus on open cardiac clamps before expanding to minimally invasive applications.
4. International Expansion and Market Development
Europe and Asia Pacific are delivering robust double-digit growth, fueled by new product launches, expanded indications, and increased clinical education. The company’s approach leverages regional training, reimbursement navigation, and targeted product introductions to maximize adoption and account activation.
