In recent years, the retrograde tibiopedal approach is increasingly being used for revascularization of complex chronic total occlusions of infrainguinal arteries to bailout those cases where a guidewire was not possible to pass through the lesion from antegrade and therefore the treatment would have failed. The present popularity of this technique is in contrast to the paucity of data published so far. Nevertheless, from the reports that are available and from the authors' experience we conclude that it is not only a successful but also a safe technique...

The current study examined whether the steroid hormone, 17β-estradiol (E2) can exert long-lasting beneficial effects upon axonal health, synaptic plasticity, dementia-related amyloid-beta (Aβ) protein expression, and hippocampal-dependent cognitive function in an animal model of chronic cerebral hypoperfusion and vascular dementia (VaD). Chronic cerebral hypoperfusion and VaD was induced by bilateral common carotid artery occlusion (BCCAO) in adult male Sprague Dawley rats. Low dose E2 administered for the first 3-months after BCCAO exerted long-lasting beneficial effects, including significant neuroprotection of hippocampal CA1 neurons and preservation of hippocampal-dependent cognitive function when examined at 6-months after BCCAO...

OBJECTIVE: To evaluate the safety and effectiveness of neglecting superficial femoral artery (SFA) recanalization for chronic lower extremity arteriosclerosis obliterans (ASO). METHODS: Thirty-six cases treated for severe stenosis or occlusion of superficial femoral artery resulted from ASO were randomly divided into 2 groups. Twenty of them were treated by endovascular reconstruction of superficial femoral artery and the other 16 cases were not treated with their superficial femoral artery, but were only treated with the accompanied iliac and/or profunda femoral artery lesion...

Inability to cross the lesion with a guidewire is the most common reason for failure in percutaneous revascularization (PCI) of chronic total occlusions (CTOs). An ostial or stumpless CTO is an acknowledged challenge for CTO recanalization due to difficulty in successful wiring. IVUS imaging provides the opportunity to visualize the occluded vessel and to aid guidewire advancement. We review the value of this technique in a single-centre experience of CTO PCI. This series involves 22 patients who underwent CTO-PCI using IVUS guidance for stumpless CTO wiring at our institution...

BACKGROUND: Although studies have demonstrated comparable efficacy and safety profiles of everolimus- and zotarolimus-eluting stents (EES and ZES, respectively) for a broad spectrum of coronary artery diseases, there is paucity of data concerning their safety and efficacy for coronary chronic total occlusions (CTOs). This study compared the clinical performance of EES and ZES following successful percutaneous coronary intervention for CTOs. METHODS: The cohort included 539 consecutive CTO patients who underwent successful PCI using EES (n=313) and ZES (n=226) between September 2006 and August 2014...

Primary percutaneous coronary intervention (PCI) is the treatment modality of choice in patients presenting with ST elevation myocardial infarction (STEMI). Clinical outcomes have dramatically improved with the wide adoption of primary PCI in patients with STEMI because of acute thrombotic native coronary artery occlusion. However, patients with prior coronary artery bypass graft (CABG) surgery who present with STEMI because of acute saphenous vein graft (SVG) occlusion continue to have worse outcomes because of poor acute and long-term results of SVG stenting...

BACKGROUND: The optimal strategy to manage chronic total occlusion (CTO) remains unclear. The Japanese CTO multicenter registry (J-CTO) score is an established tool for predicting successful recanalization. However, it does not take into account nonangiographic predictors for final technique success. In the present study, we designed and tested a scoring model called the Busan single-center CTO registry (B-CTO) score combining clinical and angiographic characteristics to predict successful CTO recanalization in Korean patients...

A 55-year-old man underwent successful percutaneous coronary intervention for the middle left circumflex artery with a 3.5 × 28-mm bioresorbable vascular scaffold (BVS). At 18 months, follow-up coronary angiography showed ectatic change with aneurysm formation over the BVS. Optical coherence tomography revealed absence of strut continuity at the aneurysm site, in the middle of the BVS. A literature review identified nine patients with intrascaffold aneurysm, including the present patient, which developed 6-32 months after BVS implantation...

Alcohol septal ablation (ASA) is an effective semi-invasive alternative to surgical myectomy in selected patients for the management of severely symptomatic and drug-refractory hypertrophic obstructive cardiomyopathy (HOCM). One contraindication of this procedure is the presence of collateral flow originating from the target septal perforator to a remote myocardial territory. In such circumstances, ethanol injection could cause remote non-target myocardial necrosis in the collateralized territory. Percutaneous revascularization of the collateralized vessel prior to ASA might cope with this contraindication by restoring normal antegrade flow in the occluded artery...
