Michael F. Mahoney
Chairman and Chief Executive Officer at Boston Scientific
Well done, Lauren. Thank you and thank you for joining us today. We're pleased with another quarter of excellent results with momentum continuing fueled by new product innovation, clinical evidence and our talented teams across the globe. In Q3 '23, total company sales grew 11% operationally and 10% organically versus Q3 '22, which exceeds the high end of our guidance range of 7% to 9%. This performance is a testament to our category leadership strategy, focus on innovation and strong commercial execution. We believe that most of our global business units grew in line or faster than their respective markets.
Q3 adjusted EPS of $0.50 grew 15% versus Q3 '22, which exceeds the high end of the guidance range of $0.46 to $0.48. Q3 adjusted operating margin was 26.1% slightly higher than anticipated. Now for '23 guidance, we're guiding to Q4 '23 organic revenue growth of 8% to 10% and aligning our full year organic guidance to approximately 11%, the high end of our prior guidance. Our Q4 '23 adjusted EPS estimate is $0.49 to $0.52 and we are raising our full year adjusted EPS range to $1.99 to $2.02.
I'll now provide additional highlights on Q3 along with comments on our 2023 outlook and then Dan will provide more details on the financials. Usually, on an operational basis, the U.S. grew 9% versus Q3 '22, driven by strong performance within our WATCHMAN, EP, endo and urology businesses. Europe, Middle East and Africa grew 11% on an operational basis versus Q3 '22. Performance for the region was broad based with double-digit growth in seven out of eight business units. Within the quarter, we saw strong growth in EP with ongoing momentum in demand for FARAPULSE and POLARx.
Asia-Pac grew 19% operationally versus third quarter '22 led by strength in Japan and China. Japan grew strong double-digits in the quarter with ongoing momentum from new products most notably AGENT DCB, Rezum, POLAR FIT and WATCHMAN FLX. Physician demand for our differentiated AGENT DCB remains high and we've taken a market leadership position within the quarter after launching earlier this year. Double-digit growth in China was led by our imaging and complex PCI portfolio as well as the commercial execution of the team more broadly. These results were further supported by the performance of the Acotec business and we continue to expect double-digit growth in China for the full year.
I'll now provide some additional commentary on the business units. In the quarter, urology sales grew 11% organically with international growth of 18% fueled by new products and globalization efforts with all regions outside the U.S. growing double-digits. Globally, the stone management franchise grew double-digits, driven by LithoVue and laser therapies. Rezum had another strong quarter of double-digit growth backed by long-term clinical data supporting international momentum with the leave nothing behind message resonating in Asia.
Endoscopy sales grew 11% organically and 12% operationally versus third quarter '22 with broad based strength across all regions. Our single use imaging and access technologies continued to perform well both growing double-digits within the quarter. And earlier this month, we received U.S. marketing authorization for an expanded indication of the AXIOS Stent to include gallbladder drainage increasing access to more patients with this platform.
Neuromodulation sales grew 3% organically versus third quarter '22. Our brain franchise grew low double-digits in the quarter with strength from new product launches, including precise Neural Navigator 5 software, which is our fifth generation DBS programming solution furthering our leadership in image guided programing for more streamlined DBS programing in the U.S. Our pain business grew low single-digits, driven by spinal cord stimulation sales, which was slightly below our expectations. We are optimistic about the opportunities ahead of our pain business including our recent U.S. approval to expand indication of our WaveWriter Alpha SCS system to include DPN, which is expected to launch in early '24.
We're also excited to add to our portfolio with our recently announced agreement to acquire Relievant Medsystems and its Intracept procedure. Intracept is the only U.S. cleared system for vertebrogenic pain extending our portfolio of pain offerings, which is expected to close in the first half of 2024. Peripheral intervention sales grew 8% organically and 13% operationally, which includes the results of Acotec versus third quarter 2002. Arterial franchise delivered another strong quarter growing low double-digits led by ongoing success globally with our drug eluting portfolio.
In venous, data from the REAL-PE study was presented earlier this week demonstrating statistically significant lower major bleeding rates in patients with pulmonary embolism who were treated with EKOS compared to a competitive mechanical thrombectomy device. The REAL-PE study analyzed nearly real-time EHR data for over 2,200 PE patients from 2009 to 2023. This study provides new clinical evidence for providers in determining the optimal modality for each patient's needs.
Our interventional oncology franchise grew double-digits including ongoing momentum with our EMBOLD coil launch as well as strong demand for our cancer therapies. Within the quarter, we received FDA clearance to expand the indication of the visual ICE Cryoablation System to treat pain associated with tumors that have metastasized to bone in patients who are unable to receive standard radiation therapy. Our cardiology group delivered another excellent quarter with organic sales growth of 11% versus third quarter '22. Within cardiology, interventional cardiology therapy sales grew 7% organically versus third quarter '22.
Our structural heart valves franchise grew double-digits in third quarter led by ACURATE neo2 sales performance in Europe and growth within our coronary therapies franchise is fueled by ongoing success of our imaging technologies. We're pleased to have received clearance for the AVVIGO+ guidance system. AVVIGO is our next-generation platform that provides high-quality fast imaging with improved physiologic assessment of coronary vessels and lesions. We continue to be pleased with the performance of AGENT DCB in Japan.
Importantly, our AGENT IDE trial results were presented yesterday as a late breaker at TCT with data demonstrating statistical superiority of the AGENT Drug Coated Balloon versus uncoated balloon angioplasty for the treatment of patients with instant restenosis. With our recent regulatory submission to FDA, we anticipate approval of AGENT, the first drug coated balloon indicator for the coronary arteries within the U.S. in the second half of '24. WATCHMAN sales grew 23% organically versus third quarter '22. We're very pleased with the excellent performance of this franchise and have now treated more than 350,000 patients globally.
Last month, we received FDA approval of the latest generation WATCHMAN FLX Pro, which is designed to improve visualization during device placement to enhance healing post implants and treat a broader range of patient anatomies. Additionally, enrollment has commenced in HEAL-LAA, a post market study of the WATCHMAN FLX Pro device in the U.S. We continue to expect strong growth from the WATCHMAN business backed by new technologies and significant investment in clinical evidence.
Cardiac rhythm management sales grew 5% organically versus third quarter '22. In core CRM, our high voltage business grew low single-digits and our low voltage business grew mid single-digits. Our diagnostics franchise grew double-digits in the quarter fueled by our diverse portfolio of ambulatory ECGs and ICM. We continue to further innovate in this space having launched in the U.S. the next-generation LUX-Dx II and the II+ implantable cardiac monitor for long-term monitoring of arrhythmias providing an enhanced diagnostic capabilities and enabling a more efficient workflow.
Electrophysiology sales grew 27% organically versus third quarter '22. International growth of 33% was driven by excellent performance from our differentiated FARAPULSE and POLARx technologies as well as our access solutions franchise and the leading inverse across access platform. U.S. growth of 22% was led by our access solutions franchise along with contribution from the early approval -- I'm sorry, from the approval of the POLAR Cryoablation System including POLAR FIT, which enables physicians to adjust and expand the cryo balloon to best fit the patient's individual anatomy.
Also within the quarter, we launched VersaCross Connect, which provides safe and efficient access to the left side of the heart during procedures expanding our access solutions portfolio. Clinical evidence generation remains a key priority and we're pleased to have completed enrollment in the first phase of the advantage AF clinical trials studying FARAPULSE for the treatment of patients with persistent AFib. Additionally, we commenced enrollment and treated our first patient in an extension arm of the ADVANTAGE study to evaluate FARAPOINT, which is a point by point PFA focal catheter for CTI ablations used to treat atrial flutter.
Finally, within the quarter, we achieved important milestones to bringing our leading PFA technology in the U.S. Recall data from our ADVENT IDE trial was presented at ESC at the end of August comparing FARAPULSE to standard-of-care thermal modalities meeting the primary endpoints. We've also completed our U.S. regulatory submission and continue to anticipate the approval of FARAPULSE in the U.S. in the second half of '24.
Through the first nine months of this year, we have grown organic sales 12%, while growing adjusted EPS 18% with broad-based growth across all of our business units and regions. This performance is supportive of the goal we laid out last month at our Investor Day where we aspire to be highest performing large cap med-tech company over the next three years. We believe our focus on talent and culture, our relentless pursuit of innovation while doing the right thing for society and operating responsibly sets us up to deliver a unique set of financial goals over the '24 to '26 long range period.
Our LRP goals include growing sales 8% to 10% CAGR over the period while expanding adjusted operating margins by 150 basis points over the three years with double-digit adjusted EPS growth annually and the improvement of our free cash flow conversion to approximately 70% by 2026.
With that, I'll pass it off to Dan to provide more details on the financials.
