Solid Biosciences Inc. has announced approvals of its IND application and CTA by the U.S. FDA and Health Canada, respectively, for SGT-501, a novel gene therapy approach for the treatment of catecholaminergic polymorphic ventricular tachycardia (CPVT), a highly malignant, arrhythmogenic channelopathy caused by mutations in the RYR2 and CASQ2 genes.

Arrhythmogenic cardiomyopathy is an inherited disorder that typically manifests in people younger than 40 years and for which only palliative treatments exist. For advanced cases, heart transplantation is the only therapeutic option.

Cellular atlases and omics studies, such as genomics, transcriptomics and proteomics, have become key tools for identifying the diversity of all the elements that make up the cardiovascular system. These approaches help scientists understand how cells, genes and molecules function and interact in both healthy and diseased conditions, revealing critical points where targeted interventions could not only relieve symptoms but potentially reverse the underlying pathology at its origin.

Boston Scientific Corp. gained a second U.S. FDA approval for its Farapulse pulsed field ablation catheter, expanding its use into drug-refractory, symptomatic persistent atrial fibrillation (AF) in addition to its existing approval for paroxysmal AF. The expanded indication marks the first of several regulatory approvals the company expects in the coming months.

After delaying a June PDUFA date, the U.S. FDA has approved Kalvista Pharmaceuticals Inc.’s Ekterly (sebetralstat) for hereditary angioedema (HAE) in those aged 12 and older. The plasma kallikrein inhibitor now joins a market with previously approved drugs for the rare, genetic, life-threatening condition, as well as other companies with HAE drugs in development. Ekterly is the first orally-delivered on-demand treatment, as all others in the U.S. are intravenously or subcutaneously administered.

Heartbeat.bio AG and Biotx.ai GmbH have partnered to identify and validate novel therapeutic targets in heart failure. The collaboration combines Biotx.ai’s causal mapping of the genome for target discovery with Heartbeat.bio’s human-based Cardioid drug discovery platform.

All kinds of substances circulate through the bloodstream. Some are beneficial, like oxygen or nutrients, and others less so, like waste products, toxins, pathogens and certain trafficking cells. Among these harmful substances are deleterious factors associated with aging, which can prematurely damage different tissues. The big question is what are those factors that mediate such effects, and what can be done to prevent them. The 11th Cardiac Regeneration and Vascular Biology Conference, held on the Island of San Servolo, Venice, from June 30 to July 2, 2025, included presentations, oral sessions and posters addressing the impact of aging on the cardiovascular system.

Field Medical Inc. continues to reap funding from investors for its pulsed field ablation (PFA) system with a $35 million oversubscribed series B financing round. With treatment of atrial fibrillation already upended by PFA technology, Field sees ventricular tachycardia as a fertile new territory for transformation.

Lunit Inc. reported a new collaboration with Microsoft Corp. July 2 to jointly develop medical AI programs accessible on Microsoft’s Azure cloud platform.

The final Medicare coverage memo for transcatheter edge-to-edge repair for tricuspid valve regurgitation largely replicates the April 2025 draft, but cardiology centers will not have to bring an electrophysiologist to the patient’s care team to be permitted to practice these devices.
