REVIEW
Mariama Akodad, Marie-Claude Morice
Though infrequent, left main stenosis has a major prognostic impact. The management of left main disease has evolved over the last few decades with the growing evidence of the efficacy and safety of percutaneous interventions, as attested by the most recent trials. However, mastery of the technical aspects of left main bifurcation stenting is essential in ensuring optimal results. This review focuses on recent data concerning left main angioplasty results as well as the current technical approaches.

A 61-year-old man with a history of percutaneous coronary intervention (PCI) of the mid right coronary artery (RCA) with a drug eluting stent (DES), presented with non-ST segment elevation myocardial infarction. Coronary angiography demonstrated complex disease of the distal RCA as well as in-stent stenosis of the previously placed mid RCA stent. The patient underwent bifurcation PCI of the distal RCA followed by attempted intervention with a DES on the mid RCA lesion. The stent could not cross the lesion and eventually became dissociated from its delivery system...

The progress and development of drug-coated balloons (DCBs) represents an emerging alternative treatment in peripheral and coronary artery diseases, particularly when a non-stent approach is necessary. Several studies and meta-analyses have evaluated the clinical outcomes of DCBs in different lesions and this review aims to compile the progress and updated clinical data of DCB strategy in both peripheral artery diseases (PAD) and coronary artery diseases (CAD). The review highlights that clinical data encouraged the use of DCB for applications in PAD and in the treatment of coronary in-stent restenosis (ISR)...

BACKGROUNDS: Drug coated balloons (DCBs) are new on stented-based anti-proliferative drug delivery systems, recently introduced in interventional cardiology. Their primary aim is to transfer an anti-proliferative drug to reduce the subsequent neo-intima hyperplasia and to maintain the normal vessel diameter and function. METHODS: A review of the most recent influential studies about DCBs in all the fields of interventional cardiology has been performed. RESULTS: As demonstrated by different studies, DCBs have different theoretical advantages over drug eluting stents (DESs), especially for the treatment of some endovascular lesions, as in-stent restenosis (ISR), coronary bifurcations, small vessels disease and peripheral artery disease at femoropopliteal and below the knee sites...

Intravascular Ultrasound (IVUS) is an intra-operative imaging modality that facilitates observing and appraising the vessel wall structure of the human coronary arteries. Segmentation of arterial wall boundaries from the IVUS images is not only crucial for quantitative analysis of the vessel walls and plaque characteristics, but is also necessary for generating 3D reconstructed models of the artery. The aim of this study is twofold. Firstly, we investigate the feasibility of using a recently proposed region detector, namely Extremal Region of Extremum Level (EREL) to delineate the luminal and media-adventitia borders in IVUS frames acquired by 20 MHz probes...

Background: Whether primary tear size impacts extent of type A dissection is unclear. Using statistical groupings based on dissection morphology, we examined its relationship to primary tear area. Methods: We retrospectively reviewed 108 patients who underwent acute ascending dissection repair from 2000-2016. Dissection morphology was characterized using 3-dimensional (3D) reconstructions of computed tomography (CT) scan images. Two-step cluster analysis was performed to group the dissections by examining the true lumen area as a fraction of the total aortic area at various levels...

BACKGROUND: The optimal strategy to treat bifurcation lesions (BFLs) in a percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) remains unknown. AIMS: We sought to assess whether T-provisional or mini-crush is appropriate for BFLs within CTO vessels. PATIENTS AND METHODS: From January 2011 to December 2013, patients who underwent successful CTO guidewire crossing and with a BFL within the CTO target vessel were enrolled prospectively and assigned randomly to either T-provisional stenting or the mini-crush technique for BFL treatment...

OBJECTIVES: To confirm clinically that coronary balloon catheter tips may be damaged during bifurcation treatment with side-branch access through the side of a stent. On the bench, we aimed to assess the susceptibility of different balloon designs to damage. We compared catheter tip widths. We tested whether balloon tip flaring can cause stent distortion. BACKGROUND: We had observed that balloon catheters that failed to cross to a side-branch frequently exhibited tip damage...

BACKGROUND: Drug-eluting stents (DES) represent a significant evolution in the treatment of patients with acute myocardial infarction with ST elevation. However, stent-related adverse events have led to an introduction of drug-coated balloons (DCB) applied particularly to bifurcation lesions, in-stent restenosis and small vessel disease. The aim of this study was to determine whether a DCB-only strategy has a similar safety profile and equal angiographic and clinical outcomes to DES implantation in primary percutaneous coronary intervention (pPCI)...

Bifurcation lesions may be encountered in approximately 15%-20% of percutaneous coronary interventions. A 2-stent approach is required in up to 30% of these procedures. We describe a novel technique based on a modification of TAP stenting, suitable for procedures where a 2-stent strategy is predetermined.
