Which TAVR device is the best? It depends, researchers say


Researchers published a paper in the Journal of the American Medical Association citing insufficient evidence regarding the superiority of TAVR devices.

Currently, only three TAVR devices are commercially available in the U.S., belonging to Edwards Lifesciences (NYSE:EW), Medtronic (NYSE:MDT) and Boston Scientific (NYSE:BSX), although several others are being used in clinical trials to evaluate safety and efficacy.

The researchers determined that, because each TAVR device on the market or undergoing clinical investigation has “fundamental differences in engineering features,” each one has its own specific strengths and limitations in the efforts to treat aortic valve stenosis through transcatheter aortic valve replacement (TAVR).

In conclusion, the researchers determined that a lack of large-scale head-to-head comparisons of the many TAVR devices, along with the continued development of new iterations of devices, means that there isn’t evidence supporting superiority for one device compared to another.

Instead, the researchers believe that, with each TAVR device design and its own unique characteristics, the favor may lean toward one or multiple specific designs based on patient-related and anatomy-related factors.
