"Wednesday after market close, NEJM published a three-center study highlighting a meaningful increase in thrombus formation in HeartMate II implants performed after March 2011 -- to 8.4% at three months post-implant from 2.2% in the period of 2004- March 2011. This high thrombus rate compares to published HeartMate II clinical trials demonstrating a three-month thrombus rate in the 2%-4% range. While THOR shares could trade down temporarily in reaction to the NEJM article, we continue to believe mid-teens LVAD market growth is sustainable over the next few years, as the study sample is still relatively small and centers are unlikely to dramatically adjust clinical practice on this study alone," said Antalffy.
"Conversely, HTWR shares could react positively to this study as it seemingly mitigates the concerns around high thrombus rates with LVADs and evens the playing field from a competitive perspective," he added.
