Thanks, Mike. Worldwide revenue for the first quarter of 2026 was $141.2 million, up 14.3% on a reported basis and 12.8% on a constant currency basis versus the first quarter of 2025. Our performance reflects substantial growth driven by the continued adoption of key new products in the United States and many regions throughout the world. On a sequential basis, worldwide revenue increased approximately 1% compared to the fourth quarter 2025. First quarter 2026 U.S. revenue was $116.2 million, a 14.9% increase from the first quarter of 2025. Open ablation product sales grew 17.3% to $39.1 million, fueled by the strong and sustained adoption of our EnCompass clamp across new and existing accounts. U.S. sales of appendage management products were $48.4 million, up 14.9% over the first quarter of 2025, driven primarily by increasing adoption of our AtriClip FLEX-Mini and PRO-Mini devices. U.S. MIS ablation sales were $6.4 million, a decline of approximately 25% over the first quarter of 2025. And finally, U.S. pain management sales were $22.4 million, up 29.5% over the first quarter of 2025, led by the cryoSPHERE MAX probe, which contributed approximately 70% of pain Management sales in the quarter, driving increased adoption in both thoracic and sternotomy procedures. International revenue totaled $25 million for the first quarter of 2026, up 11.5% on a reported basis and up 3.3% on a constant currency basis as compared to the first quarter of 2025. European sales were $16.1 million, up 13.2% and Asia Pacific and other international market sales were $8.9 million, up 8.4%. International growth was tempered by continued uncertainty in the U.K. as well as lower distributor sales in Asia. Offsetting these headwinds, we saw significant growth across franchises in other major geographies, largely driven by our direct markets. Gross margin for the first quarter of 2026 was 77.4%, up 246 basis points from the first quarter of 2025. The increase was driven primarily by favorable product and geographic mix with strong U.S. performance propelled by our new product launches and adoption. Transitioning to operating expenses for the quarter, total operating expenses increased $10.2 million or 10.3% from $98.6 million in the first quarter of 2025 to $108.8 million in the first quarter of 2026. Rapid enrollment in our BoxX-NoAF clinical trial, which offsets a decrease in LeAAPS clinical trial costs, along with increased headcount focused on product development initiatives, resulted in a 7.6% increase in research and development expense from the first quarter of 2025. SG&A expense increased 11.2% from the first quarter of 2025 as we continue to support growth while driving leverage across the organization. Completing the P&L, first quarter 2026 adjusted EBITDA was $17.1 million compared to $8.8 million for the first quarter of 2025, representing a 95% increase. We recorded net income of approximately $100,000 compared to a net loss of $6.7 million in the first quarter of 2025. Earnings per share and adjusted earnings per share were both breakeven at $0.00 compared to a loss per share and adjusted loss per share of $0.14 in the first quarter of 2025. Our results reflect a balanced approach to allocating capital towards area we believe will sustain and accelerate growth, all while continuing to improve profitability. Now turning to our balance sheet. We ended the first quarter with approximately $146 million in cash and investments. Cash burn for the quarter was slightly improved from the first quarter of 2025 and reflects our normal pattern of cash usage, driven by share vesting, variable compensation and operational needs. As we move through the remainder of the year, we expect positive cash flow, resulting in full year cash generation that is moderately higher than 2025. Our balance sheet remains healthy and supports both current operations and our investment in strategic initiatives that we believe will drive long-term value creation. And now on to our outlook for 2026. We are reiterating our expectations for full year revenue of $600 million to $610 million, reflecting growth of approximately 12% to 14% over full year 2025 results. Consistent with our first quarter results, we expect performance over the remainder of the year to be driven by our pain management, appendage management and open ablation franchises and partially offset by continuation of headwinds from our MIS ablation franchise, along with certain international markets. For the second quarter, we anticipate typical seasonality translating to mid-single-digit sequential growth. On gross margin, while our first quarter 2026 results were exceptional as a result of extremely favorable mix. We continue to expect modest improvement in full year 2026 gross margin over full year 2025. Product and geographic mix are expected to be favorable in the near term. However, we will bring our expanded manufacturing facilities online in the second half of 2026, which will increase manufacturing cost burden, moderating the full year gross margin outlook. Turning to operating expenses. As Mike mentioned, the accelerated timing for full enrollment in our BoxX-NoAF clinical trial has placed us significantly ahead of schedule, and we now expect full enrollment of the trial around the end of this year. As a result, over the next 3 quarters, we expect additional R&D investment. While the cost of BoxX-NoAF acceleration is incremental to our plan, we continue to drive strong gross margins and operating leverage, reflecting discipline across our business. With that in mind, we are reiterating our expectations for full year 2026 adjusted EBITDA of $80 million to $82 million and full year net income, translating to earnings per share of approximately $0.00 to $0.04 and adjusted earnings per share of approximately $0.09 to $0.15. Consistent with our 2025 performance, our quarterly outlook for adjusted EBITDA is largely informed by normal top line cadence and the timing of R&D spend. As a reminder, 2025 R&D spending included LeAAPS enrollment costs for the first half of 2025 only. Therefore, we expect a slightly higher increase in R&D spending in the second half of 2026. In conclusion, our first quarter results highlight the durability of AtriCure innovation and continued improvement in our financial profile while funding investments in growth catalysts for the future. We remain energized by the opportunities in front of us and the exceptional AtriCure team who will make 2026 a success. With that, I will turn the call back to Mike.
