Conflicting evidence exists on gender differences in outcomes after coronary stenting, and gender-based data in patients with chronic total occlusions (CTO) who underwent percutaneous coronary intervention (PCI) are scarce. Consecutive patients who underwent CTO PCI from January 2005 to December 2013 were included in the analysis and stratified according to gender. The primary outcome measure was all-cause mortality. Median follow-up was 2.6 years (interquartile range 1.1 to 3.1). Of 2002 patients, 332 (17%) were women...

BACKGROUND AND PURPOSE: Chronic hypoperfusion from athero-stenotic lesions is thought to lead to better collateral recruitment compared to cardioembolic strokes. It was sought to compare collateral flow in stroke patients with atrial fibrillation (AF) versus stroke patients with cervical atherosclerotic steno-occlusive disease (CASOD). METHOD: This was a retrospective review of a prospectively collected endovascular database. Patients with (i) anterior circulation large vessel occlusion stroke, (ii) pre-treatment computed tomography angiography (CTA) and (iii) intracranial embolism from AF or CASOD were included...

Beneficial properties of bioresorbable vascular scaffolds (BVS) regarding to vasomotility restoration and no caging of the vessel make them attractive devices in chronic total occlusions (CTO) revascularization. However, more evidence is needed attending to their use in this specific setting. We aim to determine feasibility and safety of BVS use in CTO revascularization attending to struts coverage and apposition, as well as re-stenosis and stent thrombosis (ST) rates. 29 BVS were deployed in 9 CTO lesions revascularization (mean J-CTO score ≥3) with an acute procedural success rate of 100%...

The careful assessment of collateral channels is important for a retrograde approach for a chronic total coronary occlusion (CTO). This case report describes a percutaneous coronary intervention for CTO of the distal right coronary artery with good collateral circulation. All visible collateral channels failed by the retrograde approach; however, the procedure was successful using the distal atrial circumflex (AC) channel. Although this distal channel was poorly visualized on standard coronary angiography, it was clearly contrasted retrogradely from the CTO exit using a super-selective injection through the proximal AC channel as the antegrade flow was obstructed by the anchor balloon...

Rotational atherectomy is performed infrequently (∼3.5%) during chronic total occlusion (CTO) percutaneous coronary intervention (PCI) for two indications: treatment of balloon uncrossable and balloon undilatable lesions. Use of rotational atherectomy in CTO PCI was associated with high success and acceptable complication rates. Rotational atherectomy remains a "must have" device for interventional cardiologists performing complex PCI.

Dissection and re-entry (DR) techniques have played a key role in the increase of success rates of chronic total occlusion (CTO) recanalization. DR usually allows wiring complex occlusions, even in case of important calcification. In extreme cases, such as in balloon failure-to-cross, rotational atherectomy (RA) might be decisive. However, according to experts' recommendations, RA should not be performed in dissection planes because of the high risk of perforation and further extending the dissection, so that its use after DR might be limited...

A chronic total occlusion in a non-infarct-related artery is an independent predictor of mortality in non-ST elevation myocardial infarction. There are no mortality data about the impact of a chronic total occlusion in patients with non-ST elevation myocardial infarction according to gender. The purpose of this study was to evaluate the prevalence of the chronic total occlusion in in men and women and examine its impact on clinical outcomes. Data from consecutive patients with multivessel coronary artery disease treated in a high-volume center between 2006 and 2012 were included in a prospective registry and divided according to gender and the presence of chronic total occlusion...

OBJECTIVES: The study sought to investigate the long-term outcomes and predictors of adverse events of percutaneous coronary intervention (PCI) for in-stent chronic total occlusion (IS-CTO). BACKGROUND: IS-CTO PCI has traditionally been associated with suboptimal success rates. METHODS: We performed a multicenter registry of consecutive patients undergoing CTO PCI at 3 specialized centers. Patients were divided in IS-CTO and de novo CTO. The primary endpoint (major adverse cardiac events [MACE]) was a composite of cardiac death, target-vessel myocardial infarction, and ischemia-driven target-vessel revascularization (TVR) on follow-up...

Background The development and use of minimally invasive procedures provide improved options for the management of symptoms of chronic venous insufficiency. While many patients with iliac venous occlusive disease and superficial venous insufficiency improve with combined iliac venous stenting and correction of superficial venous reflux, some patients have symptoms which persist. The goal of this study was to identify clinical factors related to persistent symptoms in patients with leg swelling after treatment of both iliac vein stenting and thermal ablation...

In patients with complete venous occlusion requiring venous access for cardiac device lead placement, venous revascularization is a viable option. A percutaneous approach to venous revascularization has gained popularity. This method reduces patient exposure to more invasive therapies. In this case series, we describe two cases of a total venous occlusion that were successfully revascularized using a "wire externalization" technique. This technique requires the use of antegrade and retrograde access.

BACKGROUND: Sickle cell anemia (SCA) patients exhibit sub-phenotypes associated to hemolysis and vaso-occlusion. The disease has a chronic inflammatory nature that has been also associated to alterations in the lipid profile. This study aims to analyze hematological and biochemical parameters to provide knowledge about the SCA sub-phenotypes previously described and suggest a dyslipidemic sub-phenotype. METHODS: A cross-sectional study was conducted from 2013 to 2014, and 99 SCA patients in steady state were enrolled...

Coronary computed tomography angiography (coronary CTA) is being increasingly used to detect and rule out coronary artery stenoses. Beyond stenosis detection, the abundance of anatomic, morphologic, and physiological information incorporated from a single one-stop-shop CT study has generated considerable interest in the context of preprocedural planning for coronary revascularization. Specifically, preprocedural CTA data sets can assist interventional cardiologists with selective catheter placement, appropriate guidewire choice, accurate stent size selection, and, most importantly, development of a stepwise revascularization strategy plan...
