Summary
Stenting coronary arteries without predilation using premounted stents is safe and effective in selected patients. This approach reduces procedure time and may lower the risk of dangerous coronary dissections.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Medical Device Technology
Background:
- Extensive coronary dissections are rare but serious complications of percutaneous transluminal coronary angioplasty (PTCA).
- This study evaluated stent implantation without predilatation to prevent dissections in large coronary vessels (≥ 2.5 mm).
Purpose of the Study:
- To assess the feasibility and safety of coronary stenting without predilatation in selected patients.
- To evaluate the potential of this technique to reduce procedural time and the risk of coronary dissections.
Main Methods:
- Coronary stenting without predilatation was performed in 98 patients with favorable coronary anatomy and lesion morphology (Type A and B lesions).
- Premounted stents were exclusively used.
- Patients with Type C lesions were excluded from the study.
Main Results:
- Stenting without predilatation was successful in 94% of cases (92 patients).
- Minor dissections were observed in 8% of patients, and procedural success for PTCA was 100%.
- Reduced inflation and fluoroscopic times were noted compared to standard procedures.
Conclusions:
- Coronary stenting with premounted stents without predilation is feasible and safe in selected patients.
- This technique can reduce fluoroscopic and procedural time, potentially saving costs.
- The procedure may decrease the incidence of hazardous coronary dissections.
