Abbott has initiated a Class I recall of the HeartMate 3 Left Ventricular Assist System due to a malfunction in the device’s outflow graft assembly. The company said the malfunction may cause the outflow graft to twist and close up (occlusion) over time. Occlusion of the outflow graft can reduce or stop pump flow and set off a persistent low flow alarm in the system. A reduction in pump can lead to serious adverse events such as blood clots and death. The U.S. Food and Drug Administration (FDA) has identified this as a Class I recall, the most serious type of recall.

LuxCath LLC showcased the next generation of its proprietary OmniView light-guided catheter ablation system at the 2018 Heart Rhythm Society (HRS) conference, May 9-12 in Boston. The OmniView light-guided ablation catheter is the only technology, according to the company, that can see into tissue during cardiac ablation and assess catheter-tissue contact and lesion progression in real time. This offers electrophysiologists a simple and more definitive end point for lesion quality, increasing the potential for complete and more effective cardiac ablation.
