HeartSciences Receives FDA 510(k) Clearance for its MyoVista® wavECGTM Device

Southlake, TX, Oct. 06, 2026 (GLOBE NEWSWIRE) — HeartSciences Inc. (Nasdaq: HSCS; HSCSW) (“HeartSciences” or the “Company”), a healthcare information technology (“HIT”) company focused on advancing electrocardiography (“ECG” or “EKG”) through the integration of artificial intelligence (“AI”), today announced that the U.S. Food and Drug Administration (“FDA”) has granted 510(k) clearance (K260005) for its MyoVista® wavECGTM device as a 12-lead resting electrocardiograph. The clearance covers the acquisition and interpretation of ECG signals from adult and pediatric patients in hospitals and healthcare facilities, with interpretive statements provided to clinicians on an advisory basis. The clearance does not include an AI-ECG algorithm. As previously reported, HeartSciences separated the FDA submissions for the MyoVista wavECG device and its impaired cardiac relaxation AI-ECG algorithm following updated guidance published by the American Society of Echocardiography regarding the assessment of left ventricular diastolic dysfunction. The Company does not intend to commercialize the device without a cleared AI-ECG algorithm and has made no commitment to, and has no timeline for, commercialization of the device. The clearance does, however, broaden the potential options available to the Company for the device and its related intellectual property, which the Company intends to evaluate. Andrew Simpson, CEO of HeartSciences, said, “This clearance is the result of several years of work by our clinical, regulatory and engineering teams, and I want to thank them for the quality and persistence of that effort. Our commercial focus remains on MyoVista Insights, but clearance makes the device and the intellectual property behind it a more readily realizable asset, and we will take the time to consider the best route to realizing that value.” Proposed Transaction with Fortitude The proposed business combination with Fortitude Mining Holdings, Inc. (“Fortitude”), announced in June 2026 (the “Proposed Transaction”), continues to progress. The Company expects to close the Proposed Transaction in Q4 calendar 2026, subject to customary closing conditions, including approval by HeartSciences’ shareholders.

Balt Announces First Patients Enrolled in Silk Vista Baby™ PIONEER Study

IRVINE, Calif., Oct. 01, 2026 (GLOBE NEWSWIRE) — Balt announced today it has enrolled the first patients in North America in the premarket approval (PMA) clinical trial, PIONEER (PIvotal Study Of the Silk Vista Baby Flow Diverters iN the TrEatmEnt of Unruptured Intracranial AneuRysms). Pioneer is the first prospective trial exclusively assessing the role of flow diversion in the treatment of aneurysms in distal small arteries in the brain. This landmark trial is actively enrolling at hospitals in both the U.S. and Canada and is the U.S. approval study for the Silk Vista Baby flow diverter. Co-Primary Investigator, Vitor Mendes-Pereira, M.D., MSc (St. Michael’s Hospital, Toronto, Canada) stated, “The Silk Vista Baby has been a paradigm shift in the care of neurovascular patients. It provides physicians with a significant improvement on access to distal aneurysms with a low profile microcatheter over the treatment options we have available and enables us to provide better care for more patients.” The Silk Vista Baby device was the first flow diverter in the world that delivers through a small 0.017-inch diameter microcatheter. Obtaining European Union regulatory approval in 2018, the device has been used to treat thousands of aneurysm patients around the world and studied extensively in several clinical studies. Patients with distal brain aneurysms often have those aneurysms arise off very small blood vessels and the endovascular treatment options often require access devices that are too big, or the anatomy is not suitable for open surgical solutions. “The PIONEER study is an important advance for the care of aneurysm patients in the U.S.,” said co-Primary Investigator, Ricardo Hanel, M.D., PhD (Baptist Medical Center, Jacksonville, FL), “This study will add tremendously to our knowledge of how to care for patients with distal aneurysms and potentially brings another life-saving tool to the patients of the United States. One that has already changed care for much of the rest of the world.” Balt CEO Pascal Girin commented, “PIONEER marks the second PMA trial for Balt, following the groundbreaking STEM study which resulted in the PMA approval of the SquidTM Liquid Embolic for chronic subdural hematoma patients. We are currently working on multiple additional PMA studies and are committed to continue bringing Balt’s innovative solutions to novel indications for physicians and patients around the world.” About Balt: Since it was established in 1977, Balt has worked with interventional physicians to develop devices to treat complex life-threatening neurovascular diseases such as ischemic strokes, aneurysms and other hemorrhagic conditions including arteriovenous malformations, dural arteriovenous fistulas and chronic subdural hematomas. A pioneer in the neurovascular field, Balt designs, manufactures and distributes the broadest portfolio of products in the neurovascular space and is now focused on expanding its geographic presence in the U.S. Visit Balt at https://www.baltgroup.com/   ContactGreg ChodaczekGilmartin Groupgreg@gilmartinir.com

Milestone Pharmaceuticals Enrolls First Canadian Study Participant in ReVeRA-301 Phase 3 Pivotal Trial Evaluating Etripamil Nasal Spray for AFib-RVR

Montreal Heart Institute Joins Multinational Study Evaluating a Self-Administered 70 mg Repeat-Dose Regimen of EtripamilMONTREAL and CHARLOTTE, N.C., Sept. 24, 2026 (GLOBE NEWSWIRE) — Milestone® Pharmaceuticals Inc. (Nasdaq: MIST), a biopharmaceutical company focused on the development and commercialization of innovative cardiovascular medicines, today announced that the Montreal Heart Institute, recently activated as the first Canadian clinical trial site for the ReVeRA-301 Phase 3 pivotal trial evaluating etripamil nasal spray for the treatment of atrial fibrillation with rapid ventricular rate (AFib-RVR), has enrolled their first patient. The expansion into Canada advances the multinational study toward its target of 150 patients with treated AFib-RVR events. ReVeRA-301 is evaluating the same 70 mg repeat-dose regimen that is U.S. Food and Drug Administration (FDA)-approved for paroxysmal supraventricular tachycardia (PSVT) as CARDAMYST® (etripamil) nasal spray. “Activating clinical trial sites and enrolling study participants in Canada are important steps toward advancing ReVeRA-301 and reflect the momentum behind our global enrollment efforts following the recent first enrolled patient in the United States,” said David Bharucha, M.D., PhD, FACC, Chief Medical Officer of Milestone Pharmaceuticals. “We are honored to continue our work with the strong Canadian community of cardiovascular investigators and centers with deep experience in atrial fibrillation research.” “Following the promising Phase 2 data, we are pleased to advance etripamil into this pivotal Phase 3 trial in AFib-RVR,” said Adrian Petzl, M.D., Cardiologist-Electrophysiologist, Montreal Heart Institute, and investigator on ReVeRA-301. “The ability to intervene promptly with a self-administered therapy outside of the emergency department could represent a meaningful change for patients living with this condition. We are excited that the Montreal Heart Institute is at the forefront of this global research initiative.” About ReVeRA-301 ReVeRA-301 is a Phase 3 multinational, multi-center, randomized, double-blind, placebo-controlled study to evaluate the effects of etripamil nasal spray in approximately 150 patient events with AFib-RVR. Prompted by symptoms, patients will self administer, in a medically unsupervised setting (e.g., at home), the same 70 mg dose of etripamil and repeat-dose regimen that supports the current FDA indication for the treatment of PSVT. Based on safety data demonstrated to date, Milestone is currently pursuing a single-study supplemental new drug application (sNDA) registration pathway for the treatment of AFib-RVR. The primary endpoint for ReVeRA-301 is reduction in ventricular rate (VR) within 30 minutes. The study will also evaluate a key secondary endpoint of symptom improvement via patient-reported outcomes. Clinical trial sites and enrollment information can be found at https://clinicaltrials.gov. The trial advances research from ReVeRA-201, a multi-center Phase 2, randomized controlled study of the efficacy and safety of etripamil nasal spray for the acute reduction of symptomatic AFib-RVR in an emergency room setting. The clinical trial showed that a single dose of etripamil nasal spray at 70 mg reduced VR and improved both relief of symptoms and treatment satisfaction. About Atrial Fibrillation with Rapid Ventricular Rate (AFib-RVR) Atrial fibrillation (AFib) is the most common sustained arrhythmia, affecting over 6 million people in the United States. The prevalence of AFib in Canada is similarly problematic to that in the United States. The Canadian Cardiovascular Society estimates that AFib affects approximately 1-2% of the population, up to approximately 800,000 people in Canada, and represents a substantial and growing public health burden. AFib presents with an irregular heart rate and is classified as paroxysmal, persistent, or permanent. When there is a rapid heart rate during AFib, it is referred to as “atrial fibrillation with rapid ventricular rate (AFib-RVR).” Market research indicates that 30-40% of patients with AFib experience at least one episode of RVR per year requiring urgent medical attention. These episodes commonly cause palpitations, shortness of breath, and weakness. While AFib is rarely life-threatening, it is a serious condition that often requires treatment and increases the risk of serious complications if not properly managed. Current options for acute AFib-RVR management are limited and often involve an emergency department visit for IV beta blockers, IV calcium channel blockers, or electrical cardioversion. About CARDAMYST in the United States CARDAMYST® (etripamil) nasal spray is approved by the U.S. Food and Drug Administration (FDA) for the conversion of acute symptomatic episodes of paroxysmal supraventricular tachycardia (PSVT) to sinus rhythm in adults. It is a novel calcium channel blocker nasal spray designed as a self-administered rapid response therapy for patients, thereby bypassing the need for immediate medical oversight. The product is intended to provide health care providers with a new treatment option to enable on-demand care and patient self-management. This portable treatment may provide patients with active management and a greater sense of control over their condition. CARDAMYST is well studied with a robust clinical trial program that includes a completed Phase 3 clinical-stage program for the treatment of PSVT. Currently, etripamil is in Phase 2 development for treatment of PSVT in pediatric patients and Phase 3 development for control of acute atrial fibrillation with rapid ventricular rate (AFib-RVR) in adults.
