Insights
Provisional side-branch stenting is an effective strategy for coronary artery bifurcation lesions. Technical refinements enhance its suitability for complex cases, improving procedural outcomes.
Area of Science:
- Interventional Cardiology
- Cardiovascular Surgery
Background:
- Provisional side-branch stenting is recommended for percutaneous coronary intervention (PCI) of bifurcation lesions.
- Complex bifurcation lesions remain a challenge, with many interventional cardiologists deeming provisional stenting unsuitable.
Purpose of the Study:
- To systematically review the technical aspects and refinements of provisional stenting for complex bifurcation lesions.
- To highlight the flexibility and safety of provisional stenting with specific techniques.
Main Methods:
- Systematic overview of arguments for provisional stenting strategy.
- Detailed examination of key procedural steps: branch wiring, side-branch predilation, crossover stenting, proximal optimization, kissing balloon, and side-branch rescue.
Main Results:
- Provisional stenting can be performed using various techniques.
- Specific technical refinements significantly influence procedural outcomes in complex cases.
Conclusions:
- Provisional stenting is a flexible technique for treating a wide spectrum of bifurcation lesion complexity.
- With appropriate technical tricks, provisional stenting can be performed safely and effectively.
Abstract:
A series of scientific evidence supports the concept that provisional side-branch stenting should be the preferred strategy for percutaneous coronary intervention of bifurcation coronary lesions. However, to date, many interventional cardiologists still consider this technique unsuitable for complex bifurcation lesions. This is mainly due to the fact that provisional stenting may be performed in different ways and several technical refinements may influence the procedural outcome. We here systematically overviewed the arguments which should be considered during the following steps of the provisional strategy: branch wiring, side-branch predilation, "crossover" stenting, proximal optimization, kissing balloon and the side-branch rescue techniques. We suggest that provisional stenting should be regarded as a highly flexible technique which, with specific technical tricks, may allow us to safely treat patients with wide spectrum of bifurcated lesion complexity.
