Restenosis after percutaneous coronary intervention for coronary chronic total occlusion. The central role of an optimized immediate post-procedural angiographic result.

Background: Factors of restenosis after percutaneous coronary intervention (PCI) for chronic total coronary occlusion (CTO) have not been fully explored. In particular, although the last ACC/AHA guidelines on PCI suggest that a minimum diameter stenosis of 10% with an optimal goal of as close to 0% as possible should be the new benchmark for lesions treated by stenting, angiographic success of PCI for CTO remains in the literature most often defined as a <30% residual diameter stenosis. Whether an optimized immediate post-PCI angiographic result (OAR) defined by a minimal diameter stenosis as close to 0% is associated with a lower restenosis rate in this subset of coronary lesions remains unknown.

Long-term clinical outcome and routine angiographic follow-up after successful recanalization of complex coronary true chronic total occlusion with a long stent length: a single-center experience.

Objectives: To evaluate clinical and angiographic outcomes after successful recanalization of chronic total coronary occlusion (CTO) with implantation of a long total stent length (SL).

Background: Routine follow-up angiogram (RFUA) data after successful recanalization of CTO with a long SL are lacking.

Methods: RFUAs were performed at 6 months after successful recanalization of 106 CTOs using drug-eluting stents (DESs) with a long SL (≥ 20 mm) in 102 consecutive patients.

Immediate and long-term results of a modified simultaneous kissing stenting for percutaneous coronary intervention of coronary artery bifurcation lesions.

Objectives: We propose a modified simultaneous kissing stenting technique (MSKS) based on systematic implantation of a protective stent in the proximal main vessel (PMV) proximally to the bifurcation before simultaneous kissing stenting (SKS).

Background: SKS has been proposed in large-size coronary vessel bifurcation lesions (BLs) when the PMV can accommodate two stents. SKS implies, however, low-pressure simultaneous final balloon inflations to avoid retrograde PMV dissection or rupture and therefore may not ensure optimal final stent apposition.

Simultaneous dual vascular access site for the treatment of coronary artery bifurcation lesions by complex 2-stent technique.

Objectives: To propose an original approach based on simultaneous dual vascular access site (DAS) using 2 small-size guiding catheters to easily perform complex 2-stent techniques for bifurcation coronary lesions (BL).

Background: Simultaneous kissing stenting and classic crush technique require large 7 or 8Fr guiding catheters leading to large amounts of contrast medium, vascular access site complications, and sometimes frictions or criss-cross of the 2-stent delivery systems.

Methods: DAS was used in 30 patients with BL (11 radio-radial, 16 radio-femoral, and 3 femoro-femoral).

Return to work after acute ST-segment elevation myocardial infarction in the modern era of reperfusion by direct percutaneous coronary intervention.

Background: Previous studies have evaluated return to work after acute ST-segment elevation myocardial infarction (STEMI) treated medically, after bypass surgery or after percutaneous coronary intervention (PCI) for stable coronary artery disease. However, there are few data regarding return to work after acute STEMI treated by direct PCI.

Aims: To analyse the factors influencing return to work after STEMI treated by direct PCI.
