Summer is upon us here in Europe, and we have a few things to challenge and inform you as the days get warmer...
Robotics in structural heart interventions
In this expert review, Xiang Chen, Maurizio Taramasso and colleagues bring us up to date on the latest advances in robotics for structural heart interventions. Although still limited in some cases to animal models, many transcatheter and interventional imaging procedures have seen significant developments towards robot-guided or robot-assisted interventions. In addition to a detailed review of these technologies, the authors look at the context of robotics in interventional medicine and how it might be assisted by artificial intelligence, as well as the social, technical, and safety challenges that remain.
Re-evaluating colchicine: the debate
Although colchicine is the first anti-inflammatory drug to be recommended by guidelines for the management of acute and chronic coronary syndromes, it has never received a Class I recommendation. Kevin R. Bainey and Xavier Rossello discuss whether – given the results of recent randomised controlled trials such as CLEAR SYNERGY –the recommendation for colchicine should be maintained or downgraded.
Intra- versus supra-annular SEV in small aortic annuli
Masanori Yamamoto, Kentaro Hayashida and colleagues use data from the OCEAN-TAVI registry to compare clinical outcomes and echocardiographic parameters of the latest-generation intra- versus supra-annular self-expanding valves (SEV) in patients undergoing TAVI for small aortic annuli. Both short-term valve haemodynamics and clinical outcomes were largely similar in the overall cohort and after propensity score matching. Liesbeth Rosseel, Arif A. Khokhar and Ole De Backer comment on this retrospective study in an accompanying editorial.
Antithrombotic strategies for microembolisms post-TAVI
In the AUREA trial, Victor Alfonso Jimenez Diaz, Andres Iñiguez Romo and colleagues investigate strategies to reduce cerebral embolic lesions after transcatheter aortic valve implantation (TAVI) by comparing outcomes in patients taking dual antiplatelet therapy (DAPT) versus acenocoumarol (a vitamin K antagonist) for 3 months post-procedure. Using diffusion-weighted magnetic resonance imaging at day 6, day 90 and at 1 year, the authors found a lower mean brain lesion volume at 3 months in those treated with DAPT, along with unanticipated findings on silent cerebral microembolisms in aortic stenosis patients. This article is accompanied by an editorial from George Dangas and Johny Nicolas.
4-year Myval durability
In one of the first durability studies to use Valve Academic Research Consortium-3 criteria, Akash Jain, Ignacio J. Amat-Santos and colleagues examine the Myval valve at 4 years. With primary endpoints of haemodynamic valve deterioration, bioprosthetic valve failure and patient-prosthesis mismatch, this midterm evaluation shows the Myval device to be comparable to other contemporary devices, with an 81.8% survival rate and favourable haemodynamics without significant aortic regurgitation. Philippe Pibarot and Eric Van Belle contribute an accompanying editorial.
