• Interventional Cardiology
• Medical Devices

Background:

• Coronary artery disease necessitates effective stent implantation.
• Comparing different stent delivery systems is crucial for optimizing patient outcomes.
• Hand-mounted and premounted stents offer distinct procedural advantages.

Purpose of the Study:

• To compare the 1-year angiographic and clinical results of the hand-mounted JoStent and the premounted Multi-Link Duet coronary stent.
• To assess the efficacy and safety of two distinct coronary stent models.
• To determine if there are statistically significant differences in late lumen loss, restenosis, and target vessel revascularization between the two stent types.

Main Methods:

• A multicenter randomized study involving 505 patients.
• Random assignment to either the hand-mounted JoStent (n=252) or the premounted Multi-Link Duet stent (n=253).
• Primary endpoint: late lumen loss at 1 year, with secondary endpoints including restenosis and target vessel revascularization.

Main Results:

• Statistically equivalent late lumen loss: 1.12 mm (JoStent) vs. 1.17 mm (Multi-Link Duet) (P=0.02).
• No significant difference in restenosis rates: 24.2% (JoStent) vs. 25.2% (Multi-Link Duet).
• Similar target vessel revascularization rates: 13.9% (JoStent) vs. 15.4% (Multi-Link Duet).

Conclusions:

• The hand-mounted JoStent and the premounted Multi-Link Duet stent achieve excellent procedural success rates.
• Both stent models demonstrate equally favorable 1-year angiographic and clinical outcomes.
• The choice between these stent models does not appear to significantly impact patient outcomes at one year.
