Bench Testing Analysis of Perforation Management in the Setting of Bifurcation Coronary Intervention
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Management of coronary perforation in bifurcation lesions with covered stents remains challenging. Aims We aimed to describe a proper practice and toolbox for “jailed‐branch” management after covered stent deployment. Methods Using a bench model, we tested various wires with a 120° angulated microcatheter for their ability to ...
