Brief summary

Nowadays, no studies compare the T-stenting And Minimal Protrusion (TAP) and External Minicrush techniques in treating complex coronary bifurcation, so eventually, procedural, clinical and safety differences remain unknown.

Detailed description

1. According to DEFINITION criteria, PCI of the complex coronary bifurcation with up-front two stent techniques is associated with lower target vessel revascularization (TVR) compared to Provisional Stenting 2. The Double-Kissing Crush stenting (DK-Crush) has been tested with the Culotte and the Classic Crush techniques in the unprotected left main disease (ULMD) and in no-ULMD setting, respectively, showing better clinical outcomes. 3. However, due to its technical complexity and simultaneous improvement of the Classic Crush technique evolving in the External Minicrush, it has meant that the latter has become the most used technique in the clinical practice in treating complex coronary bifurcation 4. The DK-Crush technique has never been tested with the External Minicrush, leaving the operators to choose one or the other according to their experience and preferences. 5. The T-stenting And Minimal Protrusion (TAP) is a two-stent technique described to treat coronary bifurcation after provisional treating. Compared to crush techniques, it does not require crushing of the side branch stent but only minimal protrusion of the side branch stent before main vessel stenting. 6. Nowadays, no studies compare theTAP and the External Minicrush in treating complex coronary bifurcation, so eventually, procedural, clinical and safety differences remain unknown. 7. The issue's importance is highlighted by higher rates of stent thrombosis (ST) and in-stent restenosis (ISR) of the two stent techniques compared to Provisional Stenting in treating coronary bifurcation8. 8. Consequently, investigating the efficacy and safety differences between the techniques could improve the treatment of complex coronary bifurcation to reduce post-PCI TLR.

Interventions

PROCEDUREPercutaneous Coronary Intervention

Percutaneous coronary intervention is a procedure that require coronary stenosis dilatation with dilatation catheter balloon and generally stent implantation. The study involve coronary stenosis at bifurcation level that require complex coronary techniques such as External Minicrush or TAP technique.
