This thesis provides an in-depth overview of the use of Drug-Eluting Stents for the revascularization of coronary arteries affected by atherosclerotic stenosis. Following an initial framework on the pathogenesis and clinical consequences of this condition, the analysis focuses on the structural composition of the device — metallic platform, polymer coating and antiproliferative drug — and on design criteria, geometric configuration and properties of the metal alloys used. Finally, a clinical comparison is presented with the main contemporary therapeutic alternatives, such as bioresorbable scaffolds and coronary artery bypass grafting, highlighting their advantages and limitations.
Il presente lavoro di tesi offre una panoramica approfondita sull’impiego degli stent a rilascio di farmaco per la rivascolarizzazione delle arterie coronariche affette da stenosi aterosclerotica. Dopo un iniziale inquadramento sulla patogenesi e sulle conseguenze cliniche di tale patologia, l'analisi si focalizza sulla suddivisione strutturale del dispositivo in piattaforma metallica, rivestimento polimerico e farmaco anti-proliferativo, sui criteri di progettazione dello stent, sul suo design geometrico e sulle proprietà delle leghe metalliche utilizzate. Viene, infine, proposto un confronto clinico con le principali alternative terapeutiche contemporanee, quali gli scaffold bioriassorbibili e l’intervento di bypass aorto-coronarico, evidenziando vantaggi e limiti.

Abstract
This thesis provides an in-depth overview of the use of Drug-Eluting Stents for the revascularization of coronary arteries affected by atherosclerotic stenosis. Following an initial framework on the pathogenesis and clinical consequences of this condition, the analysis focuses on the structural composition of the device — metallic platform, polymer coating and antiproliferative drug — and on design criteria, geometric configuration and properties of the metal alloys used. Finally, a clinical comparison is presented with the main contemporary therapeutic alternatives, such as bioresorbable scaffolds and coronary artery bypass grafting, highlighting their advantages and limitations.| File | Dimensione | Formato | |
