Clinical Trial Summary

The presence of a coronary bifurcation complicates percutaneous revascularization. Bifurcation stenting needs to take into account the difference of diameter between proximal and distal vessels and the necessity to limit the side branch obstruction. Provisional stenting techniques with balloon juxtaposition as Kissing Balloon Inflation (KBI) fail to demonstrate a clinical benefits. This is probably explain by the detrimental effect during these technics on the proximal segment with an arterial overstretch. A new sequential technique, named rePOT, demonstrated experimentally a mechanical superiority compared to juxtaposition balloon techniques included KBI. RePOT associates an initial proximal optimizing technique (POT), a side branch inflation and a final POT.

A first clinical study (n=106 patients) confirmed these excellent mechanical results with serial OCT analysis and demonstrated an excellent short term safety. Since 2017, rePOT is recommended in Europe in clinical practice.

This large registry is dedicated to confirm the clinical benefits at long term after bifurcation revascularization with rePOT technique before a large randomise trial.

Eligibility

Inclusion Criteria:

• Discovery, during angiography, of a significant coronary lesion (by angiographic or functional assessment) including a bifurcation under a provisional stenting strategy. Bifurcation have to be significant according to the operator and the coronary anatomy (but the side branch diameter have to be greater than 1.75mm)

• Stable lesion without high thrombus burden

• Patient agreement to study participation and = 18 years

Exclusion Criteria:

• Complex lesion or anatomy requiring revascularization strategy with more than one stent

• Contraindication to a double platelet anti-aggregation = 6mois (recommended implantation of active stent)

• Unstable patient according to the operator (used of hemodynamic drug support, mechanical ventilation)

• Indication of cardiac surgery.

• Lesion culprit in ST- or non ST-elevation myocardial infarction <12h.

• High thrombus burden in angiography or endocoronary imaging (IVUS, OCT).

• Pregnancy, loose of legal right

• Other interventional study participation <30 jours.

Related Conditions & MeSH terms

• Coronary Disease

Intervention

Other:
• Provisional stenting with rePOT technique
All revascularizations have to be performed with complete rePOT technique: initial POT + side branch inflation + final POT. Compliant or semi compliant balloon have to be preferred to inflations. The POT balloon positioning have to be precise as obtain the loose of the parallelism just at the carina cut plan. The rest of the medication or procedure characteristics stay at the discretion of the operator. The follow-up will be clinic every years.
