Summary
Direct stenting (DS) shows a lower incidence of sidebranch occlusion (SBO) compared to conventional stenting (CS), though not statistically significant. SBO risk increases with specific sidebranch morphologies and stenosis severity.
Area of Science:
- Interventional Cardiology
- Cardiovascular Research
Background:
- Direct stenting (DS) is an emerging technique for coronary artery lesions.
- While DS demonstrates high success rates, data on sidebranch occlusion (SBO) incidence remain limited.
Purpose of the Study:
- To evaluate the incidence of sidebranch occlusion (SBO) after direct stenting (DS).
- To compare SBO rates between DS and conventional stenting (CS) with balloon predilation.
Main Methods:
- A comparative study involving 151 patients undergoing percutaneous coronary intervention (PCI).
- 88 patients received DS, and 63 received CS, involving 185 jailed sidebranches.
- Sidebranch occlusion was assessed post-procedure.
Main Results:
- SBO occurred in 18.2% of sidebranches in the DS group and 24% in the CS group.
- The difference in SBO rates between DS and CS was not statistically significant (p > 0.05).
- SBO was significantly associated with type D sidebranch morphology and ostial stenosis ≥ 50%.
Conclusions:
- Direct stenting may offer a potential advantage in reducing sidebranch occlusion compared to conventional stenting.
- Further randomized trials with larger cohorts are needed to confirm these findings and optimize PCI strategies.
