BACKGROUND: Optimal imaging is essential for catheter-based interventions in CHD. The three-dimensional models in volume-rendering technique currently in use are not standardised. This paper investigates the feasibility and impact of novel three-dimensional guidance with segmented and tessellated three-dimensional heart models in catheterisation of CHD. In addition, a nearly radiation-free two- to three-dimensional registration and a biplane overlay were used. Methods and results We analysed 60 consecutive cases in which segmented tessellated three-dimensional heart models were merged with live fluoroscopy images and aligned using the tracheal bifurcation as a fiducial mark...

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.

BACKGROUND AND PURPOSE: The Barrel device is an electrolytically detachable laser cut, closed-cell microstent that is used for neck reconstruction in wide-necked bifurcation and branching aneurysms to support coiling. The key feature is a barrel section that herniates over the aneurysmal ostium. The objective was to evaluate the safety, feasibility and the immediate and mid-term occlusion results of this new device. MATERIAL AND METHODS: The databases of two tertiary care centers were screened for all Barrel-based stent-assisted intracranial coil embolization of wide-necked aneurysms between June 2015 and September 2016...

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...

PURPOSE: To describe a modified up-and-over access technique for treatment of iliac artery aneurysms in patients with prior bifurcated stent-grafts for endovascular aneurysm repair (EVAR). TECHNIQUE: This technique uses a coaxial 12-F flexible sheath that is docked with a through-and-through wire into a 7-F sheath advanced from the contralateral femoral approach. This maneuver allows both sheaths to be moved as a unit while maintaining position of the apex of the system as it loops over the flow divider, avoiding damage to or displacing the extant endograft...

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...

A comparison of the transit compartment ordinary differential equation modelling approach to distributed and discrete delay differential equation models is studied by focusing on Quartino's extension to the Friberg transit compartment model of myelosuppression, widely relied upon in the pharmaceutical sciences to predict the neutrophil response after chemotherapy, and on a QSP delay differential equation model of granulopoiesis. An extension to the Quartino model is provided by considering a general number of transit compartments and introducing an extra parameter that allows for the decoupling of the maturation time from the production rate of cells...

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...

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.

OBJECTIVES: We propose a new systematic approach in bifurcation lesions, modified jailed balloon technique (M-JBT), and report the first clinical experience. BACKGROUND: Side branch occlusion brings with a serious complication and occurs in more than 7.0% of cases during bifurcation stenting. METHODS: A jailed balloon (JB) is introduced into the side branch (SB), while a stent is placed in the main branch (MB) as crossing SB. The size of the JB is half of the MB stent size...

Premature aging occurs most frequently to various tissues and organs ultimately causing the tissue-specific chronic diseases. The mechanisms of tissue-specific premature aging are largely unknown. In response to environmental cues, aging may originate from cytoplasm or nuclear aging with the former in association with organelle degeneration in terminally differentiated cells and the latter with dysfunctional telomeres and permanent cell cycle arrest in stem and cancer cells. Either cytoplasm aging or nuclear aging may bifurcately result in extracellular senescence-associated low grade inflammation (SALI) to spread aging...

As bifurcation PCI can often be resource demanding due to the use of multiple guidewires, balloons and stents, different technical options are sometimes being explored, in different local settings, to meet the need of optimally treating a patient with a bifurcation lesion, while being confronted with limited material resources. Thereby, it seems important to keep a proper balance between what is recognized as the contemporary state-of-the-art, and, what is known as potentially harmful, and to be discouraged...
