Step by step, the description of the “biodegradable” strategy for the treatment of coronary bifurcation lesions

Metallic and Polymeric Scaffold: Too Soon to Pension the Drug-Eluting Stent

“…However, the progressive and continuous extension of scaffold use to lesion subsets previously unimaginable, such as ST-segment elevation myocardial infarction (STEMI) patients [6], chronic total occlusions [7], bifurcation lesions [8,9,10], and other complex subsets, has allowed the correction of mistakes over time, thus improving their use. It is now considered essential to follow 3 steps - predilatation, scaffold sizing, and postdilatation (PSP) - and to use the PSP score [11], where each step has its weight and role.…”
