ACC 2017: Disappointing Absorb Results Blamed On Implant Approach
Executive Summary
Two-year results of the ABSORB III trial, comparing Abbott's Absorb bioresorbable stent to its Xience metal drug-eluting stent, showed a higher risk of target vessel failure with Absorb, prompting the US FDA to send-out a "Dear Doctor" letter reiterating the importance of following the recommended implantation technique.

'All-Comers' Trial Finds Increased Risk Of Thrombosis With Abbott's Absorb BVS Stent
Preliminary two-year results from the randomized AIDA trial comparing Abbott's Absorb GT1 BVS and Abbott's Xience Prime drug-eluting stent found patients treated with Absorb were almost four times as likely to develop a stent thrombosis. The results are the latest in disappointing clinical news for the bioabsorbable scaffold.
TCT 2016: Three-Year ABSORB II Data Fail To Show The Hoped-For Long-Term Benefit Of Bioresorbable Stent
The data, presented Oct. 30 at the TCT Conference in Washington, DC, also showed higher rates of device-related adverse events including myocardial infarction with Abbott’s Absorb bioresorbable stent than a metallic drug-eluting stent, but the study was not powered to show differences in clinical endpoints, so this adverse safety signal must be evaluated in future clinical trials.
Robert Byrne: Absorb, Synergy, And The Future Of Coronary Stents
One of the most controversial, and potentially impactful, questions in medical device development today is how to better prevent late events, especially late stent-thrombosis, in coronary stent patients. The two leading answers to this question are a completely bioresorbable drug-eluting stent and a metal drug-eluting stent with a bioresorbable polymer, but there may be even more ideas on the horizon. One of the leading experts in the field and a cardiologist with experience with most of these new technologies, Robert Byrne of Deutsches Herzzentrum in Munich, recently talked to Medtech Insight about the questions that still need to be answered in this field and how it can move forward.
