Predictors of high-degree conduction disturbances and pacemaker implantation after transcatheter aortic valve replacement: Prognostic role of the electrophysiological study.

Background: Predictors of high-degree atrioventricular block (HAVB) after transcatheter aortic valve replacement (TAVR) are recognized, but the electrophysiological study's (EPS) role is still a subject to debate. The objective of our study was to determine factors associated with PPM implantation including the potential role of EPS before and/or after TAVR.

Methods And Results: Seventy four consecutive patients (pts) were included and 21 pts (28.

Impact of very high pressure stent deployment on angiographic and long-term clinical outcomes in true coronary bifurcation lesions treated by the mini-crush stent technique: A single center experience.

Background: Percutaneous coronary intervention (PCI) for bifurcation lesions (BL) using 2 stents technique is known to be associated with high rates of procedural failure especially on the side branch (SB) mainly due to stent incomplete apposition. Stent deployment at very high pressure (SDHP) may lead to better stent expansion and apposition. However, SDHP may also be at the origin of deeper wall injury resulting into major cardiac adverse events.

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.
