Implanted patches of iPS cell-derived heart muscle integrated with heart tissue in a primate model of heart failure, and in patients being treated in a clinical trial, marks progress toward a potential option for patients with advanced heart failure.

A new bioprinting platform to create tissues that can change shape as a result of forces generated by the cells, similar to what happens naturally during organ development, was developed by researchers from the University of Galway, Ireland.

Researchers from Children’s Hospital Los Angeles and the University of Southern California filed for protection of a pacemaker with a unique shape and configuration which is low profile.

Boston Scientific Corp. reported positive data for two key atrial fibrillation therapies at AF Symposium 2025 on January 17. In late-breaking data presentations, the ADVANTAGE AF trial for the Farapulse PFA system met its primary endpoints, showing a 2.3% safety event rate and 63.5% effectiveness rate in treating persistent atrial fibrillation (AF) patients, with an 85.3% symptomatic AF recurrence-free rate. Additionally, a sub-analysis of the OPTION trial demonstrated that the Watchman FLX device significantly reduced bleeding outcomes compared to oral anticoagulants.

The Medicare coverage story of the Cardiomems device has a Homeric air about it, spanning nearly a decade starting with an adverse local coverage determination in 2016.
