When choosing the correct size stent, it is important to keep Finet’s Law in mind. It is very important that it sized according to the distal main vessel reference diameter and then over-expanded, if required, in the proximal vessel using an appropriate sized balloon.
The SYNERGY Stent is indicated for treatment of patients presenting unprotected left main coronary artery lesions and has a labeled overexpansion indication of up to 5.75mm allowing the physician to customize the stent to the appropriate vessel size.
The SYNERGY 4.00mm diameter stent utilizes a customized architecture for strength and a 9% thicker (81µm) PtCr strut design3 which offers excellent radial strength. In addition, radial strength increases as diameter increases based on bench test measurements.
Adapted from a presentation by Jiang Ming Fam, MD at AsiaPCR 2015. 4.0mm diameter x 16mm length stent shown; n = 10. Data pending publication. Bench test results not necessarily indicative of clinical performance.
Bench testing performed by Boston Scientific Corporation. Data on file at Boston Scientific. All stents 2.5mm. SYNERGY Stent n = 5, all other stents are n = 3. Bench test results not necessarily indicative of clinicial performance.
The SYNERGY Stent’s bioabsorbable polymer and abluminal coating are designed for early healing as the polymer is gone when no longer needed, shortly after completion of drug elution at 3 months.
Boston Scientific is committed to supporting studies evaluating the SYNERGY Stent in patient populations that interventional cardiologists see in their everyday practice; including left main stenting.
