EuroIntervention 2013;8:1388-1397 Until a few years ago, aortic valvuloplasty had been abandoned by many centers due to its limited results and frequent complications. The current guidelines recommend aortic valvuloplasty to treat patients with symptomatic<a href="https://solaci.org/en/2013/05/21/aortic-valvuloplasty-in-the-transcatheter-aortic-valve-implantation-era/" title="Read more" >...</a>

It takes more patience to implant stents.

Original title:&nbsp;Duration of Balloon Inflation for Optimal Stent Deployment: Five Seconds Is Not Enough.&nbsp;Reference:&nbsp;Thomas Hovasse et al. Catheterization and Cardiovascular Interventions 81:446&ndash;453 (2013). Adequate stent expansion and apposition to the vessel wall is essential to optimize the results of percutaneous transluminal coronary angioplasty (PTCA). If the above is not adequate, it increases the risk of<a href="https://solaci.org/en/2013/02/22/it-takes-more-patience-to-implant-stents/" title="Read more" >...</a>

Clinical Significance of Collaterals in Chronic Total Occlusions

Again in the bifurcation, less is more.

It has been reported that the two stents technique is not superior to a provisional stent when treating bifurcations. However, the optimal approach to rescue a secondary branch (SB) when initially opting for provisional stenting has not been established.  &nbsp; The aim of this study was to determine angioplasty indication using balloon or stent for<a href="https://solaci.org/en/2012/11/20/again-in-the-bifurcation-less-is-more/" title="Read more" >...</a>
