The concept of TAVR(Trancutaneous aortic valve replacement ) is trying hard  to prevail over surgical aortic valve replacement .Two companies Medtronic and Edwards life have their products (Core and Sapiens)  tested and used with varying success.Meanwhile, Boston scientific has come out with a new one , Lotus valve made with stainless steel and bovine pericardium.

Lotus valve  seems to have a distinct  advantage* (over the Core and Sapiens ) in terms of easy delivery and adjustment (or retrieval ) of valve till  final position and efficient adoptive steel technology in preventing para-valvular leak.

* Outcome awaited.

Human  trials has started with lotus valve in USA 2014.The REPRISE III trial would compare  one to one Lotus vs core valve . Results will be out by 2017.Unlike many interventions the utility value and long-term outcome of  TAVR  seem to be genuine and patients  waiting for aortic valve surgery can look forward to this as a genuine non surgical alternative.

Responding to this , Medtronic and Edwards are  improving upon core valve with Evolute R /Engager and SAPIEN3 , expected  to give a tough time for LOTUS.
