Interventional cardiology is experiencing a major advancement with the development of bioresorbable vascular scaffolds (BVS), also known as dissolvable heart stents. Unlike permanent metal stents that remain in the artery forever, these temporary scaffolds provide structural support to narrowed or blocked coronary arteries only during the critical healing period, typically six to twelve months.Made from biocompatible materials such as polylactide (PLLA) polymers or magnesium alloys, the stents gradually break down through natural metabolic processes. PLLA-based scaffolds are converted into lactic acid, which the body further metabolizes into water and carbon dioxide. Magnesium scaffolds are similarly absorbed and excreted. The entire process is usually complete within two to three years, leaving no foreign material behind.This “vanishing” property allows the treated artery to restore its natural flexibility, pulsation, and vasomotor function — abilities often permanently restricted by rigid metal implants. By disappearing, these stents also reduce long-term risks such as chronic inflammation, late thrombosis, and in-stent restenosis. They may also make future interventions easier and improve overall vessel health.While early versions faced some limitations (particularly in smaller vessels), newer generations of bioresorbable stents continue to improve in strength, deliverability, and safety. This technology represents a significant shift in cardiovascular care — moving away from permanent mechanical support toward temporary assistance that ultimately restores the artery’s natural state.[Byrne, R.
