CAR T cells engineered to target fibroblast activating protein (FAP) could reverse cardiac fibrosis and restore cardiac function in mice, researchers have reported in the Sept. 12, 2019, issue of Nature.

The recent progress in interventional cardiology has largely been driven by the aortic valve, although calcification of the aortic root has proven a difficult hurdle to overcome. A newly published study demonstrates that the Tendyne device by Abbott Vascular Inc., of Santa Clara, Calif., can be readily used not just to treat failing mitral valves, but works well in these patients with severe calcification, an achievement that could quickly vault the transcatheter approach past conventional surgical approaches in this population.

The FDA has granted breakthrough device designation to Sonivie Ltd.'s Therapeutic Intra-Vascular Ultrasound (TIVUS) system for the treatment of pulmonary arterial hypertension (PAH). Early clinical studies suggest that the catheter-based system could stabilize or reduce pressure in the pulmonary vasculature of PAH patients, a population with an average survival rate of five years.
