Late Breaking Data from Independent Government-Funded Trial at ESC Shows Heartflow FFRCT Analysis Reduces Unnecessary Invasive Heart Procedures by Nearly Half

Coronary/Structural Heart by 0 comments

FUSION trial presented at ESC and published in Journal of the American College of Cardiology demonstrates adding non-invasive lesion-specific physiology resolves critical diagnostic uncertainty, supporting Appropriate Use Criteria for cath lab referralsSAN FRANCISCO, Aug. 28, 2026 (GLOBE NEWSWIRE) — Heartflow, Inc. (Heartflow) (Nasdaq: HTFL), the leader in AI technology for diagnosing and managing coronary artery disease (CAD), today announced late-breaking one-year results from an independent randomized clinical trial proving the Heartflow FFRCT Analysis safely and significantly reduced unnecessary invasive heart procedures by 44% (p < 0.001). Presented as Late-Breaking Science at the European Society of Cardiology (ESC) Congress 2026, FUSION trial, funded by the Dutch National Health Care Institute, demonstrates that standard coronary computed tomography angiography (CCTA) alone drives overutilization of invasive catheterizations.1 By adding Heartflow FFRCT Analysis to standard CCTA scans, clinicians dramatically reduced diagnostic catheter lab procedures. The FUSION study has been published simultaneously in the Journal of the American College of Cardiology (JACC). CCTA is the primary first-line test recommended by both European (ESC) and U.S. (ACC/AHA) guidelines for evaluating patients with suspected CAD. However, visual assessment of CCTAs is limited to assessing anatomy and whether plaque is present; it cannot determine lesion-specific physiology or whether a blockage significantly restricts blood flow to the heart. This diagnostic uncertainty frequently leads physicians to refer patients for invasive coronary angiography (ICA), a hospital procedure where a catheter is threaded through an artery, normally in the groin or arm, to get into the heart to assess blocked or narrowed blood vessels.1,2,3,4 These findings show Heartflow FFRCT – the only AI platform prospectively validated against invasive gold standard – bridges this critical diagnostic gap. By applying advanced AI and computational fluid dynamics to standard CT scans with documented narrowings, Heartflow creates a personalized 3D model that quantifies blood flow within the coronary arteries.5 “CCTA is established as the optimal first-line diagnostic test for coronary artery disease as it is noninvasive, but when anatomical scans show intermediate stenosis, determining whether that blockage is clinically significant remains a critical challenge,” said Alexander Hirsch, M.D., principal investigator of the FUSION trial and associate professor of cardiology at Erasmus MC in Rotterdam, Netherlands. “The FUSION trial shows that adding Heartflow lesion-specific physiology makes CCTA even more powerful and improves diagnostic efficiency. It gives clinicians the clarity to know which patients require further invasive testing, safely avoiding unnecessary invasive catheterizations while maintaining excellent patient outcomes.” One-Year FUSION Results Enrolling 528 patients with stable chest pain across twelve hospitals in the Netherlands, FUSION is an independent randomized controlled trial funded through the Dutch government’s Zorginstituut Nederland ‘Potentially Promising Care’ program. The study evaluated Heartflow FFRCT Analysis across diverse scanner vendors in both academic and community hospital settings, with blinded, independent clinical event adjudication. Key 1-year findings include: A sustained 44% relative reduction in unnecessary ICA was demonstrated at one year in the Heartflow pathway compared to the CCTA-only group (22% [57/263] Heartflow vs. 39% [103/265] CCTA alone; p < 0.001), consistent with the 90-day primary endpoint results (18% [48/263] vs. 33% [87/265] CCTA alone; p < 0.001).Overall rates of ICA were significantly lower at one year in the Heartflow pathway compared to the CCTA-only group (43% [114/263] Heartflow vs. 61% [161/265] CCTA alone; p 50% non-obstructive rate in usual care elective caths).2 Gulati M, et al. 2021 AHA/ACC/ASE/CHEST/SAEM/SCCT/SCAI Guideline for the Evaluation and Diagnosis of Chest Pain.

Philips and Imricor launch cardiac interventional MR lab solution, expanding longstanding collaboration

Financial Radiology by 0 comments

Philips MR

Philips and Imricor’s new iMR lab solution combines 1.5T MRI with MR-compatible systems and tools to support MR-guided cardiac interventions.

August 27, 2026 The solution combines Philips’ high-performance 1.5T MRI platform and advanced interventional workflow capabilities with Imricor’s exclusive portfolio of systems and consumables for MR-guided cardiac interventions. Amsterdam, the Netherlands – August 27, 2026: Royal Philips (NYSE: PHG, AEX: PHIA), a global leader in health technology, and Imricor Medical Systems (ASX: IMR), a pioneer and world-leading developer of MR-compatible products for interventional MR procedures, today announced a new Interventional MR (iMR) lab solution for Philips 1.5T MR. The first commercially available configuration [1] combines Philips’ 1.5T MRI platform and Imricor’s portfolio of iMR systems and consumables, enabling an MR-guided workflow for cardiac intervention, without compromising on MR field strength.  Meeting the need for greater tissue insight during cardiac intervention Cardiac arrhythmias affect millions of people worldwide, and catheter ablation is an established and increasingly utilized treatment for many complex cardiac arrhythmias. Yet today, these procedures continue to rely primarily on X-ray fluoroscopy, which provides only indirect visualization of soft tissue while exposing patients and clinical teams to ionizing radiation.  MRI has already transformed cardiac diagnosis by enabling clinicians to visualize cardiac anatomy and tissue in exceptional detail. Bringing that same level of tissue insight into intervention has the potential to help physicians guide therapy more precisely, assess treatment response during procedures and identify potential therapy gaps before a patient leaves the procedure room – all within a radiation-free work environment of an iMR.  “Our ambition is not only to advance what clinicians can see with MRI, but also what they can do with it,” said Ioannis Panagiotelis, PhD, Business Leader, Magnetic Resonance at Philips. “Philips has a long history of helping clinicians perform image-guided procedures with confidence, and we believe MRI can play an even greater role in providing care. With this new iMR lab solution, enabled through our collaboration with Imricor, we’re expanding the role of cardiac MRI from diagnosis into the treatment environment.”  Panagiotelis added, “Cardiac electrophysiology is just the beginning. This iMR lab solution represents an important step in Philips’ strategy to advance MRI across the care continuum, creating a platform that can expand into additional clinical areas while helping clinicians deliver the best possible care for their patients.” iMR built on Philips’ leading cardiac 1.5T MRI platform The iMR lab solution combines Philips’ high-performance 1.5T MRI platform with Imricor’s portfolio of MR-compatible systems and consumables to create a complete, connected environment for MR-guided cardiac intervention – marking the next milestone in the companies’ long-standing collaboration to bring MR-guided cardiac intervention into routine clinical practice.  The first commercially available configuration includes Philips’ Cardiac MR Suite, featuring SmartHeart AI-powered cardiac planning and advanced cardiac imaging applications alongside Imricor’s NorthStar® iMR mapping and guidance system, Advantage-MR® EP Recorder/Stimulator and Vision-MR® family of electrophysiology catheters [2]. Together, these technologies enable physicians to visualize cardiac anatomy and arrhythmia substrate, actively track catheters, perform electroanatomical mapping, assess lesion formation and evaluate treatment response throughout procedures within Philips’ 1.5T MR environment.  For hospitals, the iMR lab solution provides a turnkey platform for MR-guided cardiac intervention, bringing together advanced imaging, intelligent workflows and MR-compatible interventional technologies. The solution is built on Philips’ BlueSeal helium-free MRI technology[3], reducing siting complexity and enabling installation closer to cardiology departments, helping support adoption today while establishing a scalable foundation for future iMR-guided procedures.  “With interventional MR, the idea is not to move procedures into diagnostic MRI suites, but rather to bring MR imaging into the procedure room, a room we call an iMR lab,” said Steve Wedan, Founder and CEO of Imricor. “Our collaboration with Philips has always been driven by this shared vision, and with our combined iMR lab solution, that vision becomes a reality today. Pairing Philips’ world-class 1.5T MR platform with Imricor’s exclusive portfolio of advanced iMR systems and interventional tools creates the world’s first state-of-the-art high-performance iMR lab solution. We believe the future is about advanced image guidance for therapies and interventions, and the future is here now.”  The iMR lab solution will be showcased in Munich at ESC Congress 2026 and is commercially available immediately in CE-marked markets and, in some configurations, the U.S. Further Imricor configurations are expected to become available in the U.S. and additional markets, subject to regulatory clearances.  [1] Philips issued a Third-Party Product Compatibility Declaration for Imricor’s interventional MRI (iMR) equipment and consumables.  [2] NorthStar and the Vision-MR Diagnostic Catheter are commercially available in the U.S. Other Imricor products are not yet cleared/approved for sale in the U.S. [3] Helium-free operations. 7 liters of helium is permanently enclosed in the cryogenic circuit.  For further information, please contact: Name Jayme ManiatisPhilips Global External RelationsTel.: +16178948368E-mail: jayme.maniatis@philips.com About Royal Philips Royal Philips (NYSE: PHG, AEX: PHIA) is a leading health technology company focused on improving people’s health and well-being through meaningful innovation.

Milestone Pharmaceuticals Announces Data Presented at ESC Congress 2026 on the Impact of Paroxysmal Supraventricular Tachycardia (PSVT) on Patients’ Daily Lives and Quality of Life Between Episodes

Coronary/Structural Heart by 0 comments

Research Shows that Patients with PSVT Experience a Substantial Burden Between Episodes, with Negative Impacts on Anxiety, Daily Activities, Sleep, and WorkMONTREAL and CHARLOTTE, N.C., Aug. 27, 2026 (GLOBE NEWSWIRE) — Milestone® Pharmaceuticals Inc. (Nasdaq: MIST), a biopharmaceutical company focused on the development and commercialization of innovative cardiovascular medicines, today announced findings from a longitudinal study describing how paroxysmal supraventricular tachycardia (PSVT) affects patients’ daily lives and quality of life in the periods between episodes. The findings are being presented in a moderated ePoster session titled “The Impact of PSVT on Patients’ Daily Life and QoL in Between Episodes” at the European Society of Cardiology (ESC) Congress 2026 on August 30, 2026, 15:15-16:00 CET, Station 6, Research Gateway, Hall A1. “This study’s findings broaden our understanding of the patient experience with PSVT and show that its impact can extend well beyond the acute episode,” said Sean D. Pokorney, M.D., MBA, Assistant Professor of Medicine, Duke University Medical Center and the Duke Clinical Research Institute, and study presenter. “The changes patients reported in activities such as driving, travel and exercise, together with persistent anxiety between episodes, illustrate a burden that is not captured by looking at episode frequency or duration alone.” PSVT is a common heart rhythm disorder in which the heart suddenly beats very fast affecting an estimated two million people in the United States. The acute symptoms of a PSVT episode are well recognized. However, the impact of living with the condition between episodes has not been well established. This study assessed patient-reported outcomes over nearly a year, capturing how PSVT shaped participants’ activities, emotions, and quality of life outside of a healthcare setting. The results show that many people living with PSVT change their behavior, avoid everyday activities, and carry anxiety with them even when they are not having an episode. Key Findings Approximately two in three patients adjusted their lifestyle between episodes to avoid stress, and nearly 40% reduced their activity or exercise routine because of PSVT.73% of patients reported daytime activity interruption between PSVT episodes.Automobile driving (53%) and travel (43%) were the everyday activities for which avoidance between PSVT episodes was most frequently rated as bothersome or extremely bothersome (score of 6 or 7 on a 7-point scale).Anxiety persisted between PSVT episodes. Patients reported an average anxiety level of 3.1 on a 7-point scale; 26% of patients reported feeling extremely anxious at some point during the study, and 16% reported the maximum anxiety score at least once.Side effects of medications taken chronically (e.g., daily) for PSVT were frequently reported as burdens. Fatigue and weakness were each rated as bothersome or extremely bothersome (6 or 7 on a 7-point scale) by 65% of patients.Sleep (30%) and capacity for work (22%) were the most commonly reported areas of lifestyle dissatisfaction (score of 1 or 2 on a 5-point scale). Conclusions PSVT imposes a substantial quality-of-life burden between episodes, affecting anxiety, daily activities, sleep, and work. Medication side effects and activity avoidance further contribute to this burden, underscoring that the impact of PSVT extends beyond acute symptomatic episodes and highlighting an unmet treatment need.The authors call for future research to evaluate the quality-of-life impact of at-home, self-administered treatments to terminate PSVT episodes. The prospective, longitudinal, web-based survey study enrolled 247 adults in the United States and United Kingdom with a self-reported diagnosis of PSVT and no history of catheter ablation at enrollment. Participants completed a baseline survey in February 2019, weekly tracking surveys through December 2019, and a closing survey. During weeks without a PSVT episode, participants completed quality-of-life assessments, including the World Health Organization Quality of Life–Brief Version (WHOQOL-BREF), and answered questions about lifestyle changes, avoidance behaviors, emotional symptoms, and anxiety. Participants had a mean age of 52 years, 72% were female, and the population carried a substantial comorbidity burden. The study was funded by Milestone Pharmaceuticals. “Better understanding the impact of PSVT on the patients’ daily lives – including between acute events – is important as we consider the management and treatment options which can more fully address the needs of people living with this condition,” said David Bharucha, M.D., PhD, FACC, Chief Medical Officer of Milestone Pharmaceuticals. About Paroxysmal Supraventricular Tachycardia (PSVT) An estimated two million people in the United States are currently diagnosed with PSVT, which is a type of arrhythmia or abnormal heart rhythm. PSVT is characterized by episodes of sudden onset rapid heartbeats often exceeding 150 to 200 beats per minute. The heart rate spike is unpredictable and may last several hours. The rapid heart rate often causes disabling severe palpitations, shortness of breath, chest discomfort, dizziness or lightheadedness, and distress, forcing patients to limit their daily activities. The uncertainty of when an episode of PSVT will strike or how long it will persist can provoke anxiety in patients and negatively impact their day-to-day life between episodes. The impact and morbidity from an attack can be especially detrimental in patients with underlying cardiovascular or medical conditions, such as heart failure, obstructive coronary disease, or dehydration. Many healthcare providers are dissatisfied with the lack of effective treatment options, with patients often electing to pursue prolonged, burdensome, and costly trips to the emergency department or even undergo invasive cardiac ablation procedures. About Milestone Pharmaceuticals Milestone Pharmaceuticals Inc. (Nasdaq: MIST) is an emerging commercial-stage biopharmaceutical company advancing innovative cardiovascular medicines to benefit people living with certain heart conditions. Milestone’s lead product is CARDAMYST® (etripamil) nasal spray, a novel calcium channel blocker, which is FDA-approved for the conversion of acute symptomatic episodes of paroxysmal supraventricular tachycardia (PSVT) to sinus rhythm in adults. Etripamil is also in Phase 3 development for the control of symptomatic episodic attacks associated with AFib-RVR. https://milestonepharma.com/ Contact:Investor RelationsKevin Gardner, kgardner@lifesciadvisors.com Media RelationsRebecca Novak, rnovak@milestonepharma.com

Cardurion Pharmaceuticals Announces Late-Breaking Presentation of Phase 2 Results for Tovinontrine (CRD-750), a PDE9 Inhibitor, in Heart Failure

Coronary/Structural Heart by 0 comments

Results from two Phase 2 clinical trials assessing tovinontrine in both major types of chronic heart failure will be presented at the Heart Failure Society of America annual scientific meetingBURLINGTON, Mass., Aug. 27, 2026 (GLOBE NEWSWIRE) — Cardurion Pharmaceuticals, Inc. (“Cardurion”), a clinical-stage biotechnology company discovering and developing new therapeutic approaches for the treatment of patients with cardiovascular diseases, today announced that the Company will present results from the Phase 2 CYCLE clinical trials evaluating tovinontrine (CRD-750), a novel phosphodiesterase-9 (PDE9) inhibitor, in chronic heart failure. The results will be presented in late-breaking presentations at the Heart Failure Society of America (HFSA) Annual Scientific Meeting in Phoenix, Arizona taking place on October 9–12, 2026. Tovinontrine is an orally administered PDE9 inhibitor that represents a new mechanism to enhance the natriuretic peptide signaling (NPS) pathway, a clinically validated pathway for the treatment of patients with heart failure. Cardurion is the first company to bring a PDE9 inhibitor into clinical development for the treatment of chronic heart failure. “We look forward to sharing the exciting results from our CYCLE trials, which represent the first time that robust Phase 2 data have been completed for PDE9 inhibition in heart failure. Despite current standard of care, a large unmet medical need remains, and patients with chronic heart failure continue to experience high rates of morbidity and mortality,” said Howard Surks, MD, Chief Medical and Scientific Officer of Cardurion. “It is a major milestone for our company to successfully complete this large, global clinical program in both major types of heart failure, and the results of the CYCLE studies will guide the next stage of clinical development for tovinontrine as we move closer to our goal of bringing this novel PDE9 inhibitor to patients with chronic heart failure.” The presentations at HFSA in October will describe the results from Cardurion’s global, multi-center, Phase 2 clinical trials (NCT06215911 and NCT06215586) assessing the safety and efficacy of tovinontrine in the two major types of chronic heart failure: heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF). Details for the presentations at HFSA are as follows: CYCLE-1 REF presentation title: A Phase 2, Randomized, Double-Blind, Placebo-Controlled, Dose-Finding Study to Assess the Safety and Effectiveness of Tovinontrine (CRD-750) in Patients With Chronic Heart Failure With Reduced Ejection Fraction: The Cycle-1 REF TrialCYCLE-2 PEF presentation title: A Phase 2, Randomized, Double-Blind, Placebo-Controlled, Clinical Study to Assess the Safety and Effectiveness of Tovinontrine (CRD-750) in Patients With Chronic Heart Failure With Preserved Ejection Fraction: The Cycle-2 PEF Trial About PDE9 InhibitionPhosphodiesterase (PDE) 9 is an enzyme whose elevated activity in patients with heart failure reduces the beneficial effects of the natriuretic peptide signaling (NPS) pathway. The NPS pathway plays an important and protective role in cardiac function, and its activation has been shown to confer outcomes benefit for patients with heart failure. PDE9 is significantly upregulated in patients with chronic heart failure, causing disruption in the NPS pathway. Cardurion is the first company to demonstrate clinical proof-of-mechanism for PDE9 inhibition in patients with chronic heart failure with its PDE9 program. About Heart FailureHeart failure is a prevalent and growing condition that is responsible for substantial morbidity and mortality. Approximately 6.7 million adults in the United States suffer from heart failure, and approximately 50 percent of these patients die from the condition within five years of diagnosis. One in five patients with heart failure are hospitalized annually, and approximately 25 percent of these patients are re-admitted within a month of discharge. Approximately half of all patients with chronic heart failure have reduced ejection fraction (HFrEF) and half have preserved ejection fraction (HFpEF), categorized as different diseases based on the pumping ability of the heart. Significant unmet medical needs remain in heart failure, despite the reductions in morbidity and mortality from currently approved treatments for heart failure.
