Pulsed field ablation dominated the news out of the Heart Rhythm Society meeting this week with three late-breaking studies highlighting the safety and efficacy of the technology replacing thermal ablation for treatment of atrial fibrillation and active discussion of the ‘unprecedented’ growth of these procedures. Boston Scientific Corp’s Farapulse is rapidly building dominance in the field, while results from Johnson & Johnson’s Varipulse study and Medtronic plc’s trial of the Affera system set up those companies for U.S. FDA approval later this year.
The Surveillance Heartcare Outcomes Registry trial demonstrated that Caredx Inc.’s Heartcare test identifies acute cellular rejection in heart transplant patients better than donor-derived cell-free DNA (dd-cfDNA) alone, while reducing biopsies and improving clinical outcomes. Heartcare combines two non-invasive tests, dd-cfDNA and Allomap Heart gene-expression profiling.

Field Medical Inc. kicked off its first-in-human study for its Fieldforce ablation system, designed for use in ventricular arrhythmias. The Ventricular Catheter Ablation Study study will enroll 60 patients in five centers around the world, most recently kicking off in the Na Homolce Hospital in Prague, Czech Republic.
This time a positive result for a cancer screening test brought good news, as Geneoscopy Inc. secured U.S. FDA approval for its RNA screening test for colorectal cancer.

Masimo Corp.’s pride and joy, the Stork baby monitor, achieved a new developmental milestone with U.S. FDA clearance for over-the-counter marketing.
