The sedate uptake of pulsed field ablation (PFA) in Europe failed to presage the enthusiasm that drove the technology’s extraordinarily rapid adoption in the U.S. in 2024. Used to treat atrial fibrillation, PFA received its first U.S. FDA approval in Dec. 2023. At the time, Clarivate estimated that PFA had 7% of the global cardiac ablation market. By year-end 2024, it had 20% and Boston Scientific Corp. projected that PFA would represent up to half of the market by the close of 2025.

U.S. Medicare coverage of renal denervation (RDN) for uncontrolled hypertension may soon be a fact of life if the manufacturers of these systems have their way. CMS opened a national coverage analysis for RDN, but as is routine practice recently, the agency is asking for comment before posting even a draft coverage memo for this technology.

Timing is everything. Just days after confirming a pause in the U.S. rollout of its Varipulse pulsed field ablation (PFA) catheter, Johnson & Johnson’s electrophysiology program received an epic reprieve from European regulators who granted the company’s dual-energy Thermacool Smarttouch SF catheter CE mark.

Researchers from The George Washington University and Northwestern University filed for protection of a bioresorbable, transparent, microelectrode array (MEA) technology that they believe offers unique advantages.

Affinia Therapeutics Inc. has nominated AFTX-201 as a development candidate for the treatment of BAG3 dilated cardiomyopathy. The gene therapy, using Affinia’s cardiotropic capsid, is given as a one-time intravenous injection.

New Anglo/U.S. obesity and cardiometabolic specialist Verdiva Bio Ltd. has launched with a massive $411 million series A and a portfolio of GLP-1 and amylin agonists in-licensed from China.

Johnson & Johnson halted the limited rollout of its Varipulse pulsed field ablation system on Jan. 5 to “investigate the root causes of four reported neurovascular events in the U.S. external evaluation.” So far, just 130 cases have been completed in the U.S. since the company received U.S. FDA approval in November for use in paroxysmal atrial fibrillation.

Fire1 Ltd. secured $120 million in financing to conduct a pivotal trial for its heart failure management system, Norm. The technology measures fluid in the inferior vena cava (IVC) and is expected to help the millions of people living with heart failure manage their condition and get their normal life back.

The company is advancing a pipeline of therapeutics, including programs acquired from Denali Therapeutics Inc., focused on treating neurological, cardiometabolic and ophthalmic diseases.

Fauna Bio Inc. has nominated Faun-1083 as its first development candidate, for the treatment of heart failure with preserved ejection fraction (HFpEF). Faun-1083 is a novel small-molecule therapeutic that has demonstrated promising in vivo efficacy in multiple preclinical animal models.
