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).
