OBJECTIVES: Data on bioresorbable vascular scaffolds for recanalization of chronic total occlusions (CTOs) are limited. We compared the bioresorbable scaffold Absorb with everolimus-eluting stents for the treatment of true CTO. METHODS: After recanalization of CTO, 15 lesions treated with the bioresorbable scaffold Absorb were matched with 15 lesions receiving everolimus-eluting stent (EES) (http://www.clinicaltrials.gov NCT02162082). Match criteria were presence of diabetes mellitus, total device length and maximal device diameter...

BACKGROUND: Patients with chronic total occlusions of a coronary artery represent a complex, yet common, clinical conundrum among patients with ischemic heart disease. Chronic total occlusion angioplasty is increasingly being used as a treatment for these complex lesions. There is a compelling need to better quantify the safety, efficacy, benefits, and costs of the procedure. METHODS: To address these gaps in knowledge, we designed the Outcomes, Patient Health Status, and Efficiency IN Chronic Total Occlusion Hybrid Procedures (OPEN CTO) study, an investigator-initiated multicenter, single-arm registry including 12 centers with a planned enrollment of 1000 patients...

BACKGROUND: Few data are available on long-term follow-up of DES in the treatment of chronic total occlusion (CTO). The LEADERS CTO sub-study compared the long-term results in CTO and non-CTO lesions of a Biolimus A9™-eluting stent (BES) with a sirolimus-eluting stent (SES). METHODS: Among 1,707 patients enrolled in the prospective, multi-center, all-comers LEADERS trial, 81 with CTOs were treated with either a BES (n = 45) or a SES (n = 36). The primary endpoint was the occurrence of major adverse cardiac events (MACE): cardiac death, myocardial infarction (MI) and clinically-indicated target vessel revascularization (TVR)...

OBJECTIVES: This study sought to assess the impact of chronic total occlusion (CTO) on long-term prognosis in patients with ischemic cardiomyopathy. BACKGROUND: The presence of concomitant CTO in a nonculprit lesion in acute coronary syndromes is associated with worse prognosis. Coronary artery disease is the main cause of heart failure and in many cases at least 1 CTO is observed. METHODS: The study included all patients with systolic heart failure who underwent elective coronary angiography and were registered from January 2009 to December 2014 in the ongoing single-center COMMIT-HF (COnteMporary Modalities In Treatment of Heart Failure) registry (NCT02536443)...

BACKGROUND: Excimer laser coronary atherectomy (ELCA) recently became available in Japan, but ELCA's effectiveness and safety are not clear. METHODS AND RESULTS: We enrolled consecutive patients who underwent ELCA and were registered in the Utility of Laser for Transcatheter Atherectomy-Multicenter Analysis around Naniwa (ULTRAMAN) registry comprising six Japanese medical centers around Naniwa in Japan with patients registered from April 2006 to June 2015. We evaluated the catheter sizes used and compared the success rate, thrombolysis in myocardial infarction (TIMI) flow, blush score, and complications between the rich-thrombus (RT) group [acute coronary syndrome (ACS) and saphenous vein graft (SVG)] and the poor-thrombus (PT) group [in-stent restenosis (ISR), chronic total occlusion (CTO), calcification, and long or bifurcation (L&B) lesions]...

Chronic total occlusions (CTOs) are frequently detected on diagnostic coronary angiograms. For the selection of patients for CTO percutaneous coronary intervention, factors such as the level of symptoms, level of myocardial viability and extent of ischemia must be taken into account. Remarkable progress has been achieved in the success of complex CTO procedures during the past decade. In addition to antegrade wire escalation strategy, subintimal passage of the guidewire with or without dissection and re-entry techniques and retrograde techniques can be utilized...

INTRODUCTION: The bioresorbable vascular scaffold system (BVS) is the latest fully absorbable vascular therapy system that is used to treat coronary artery disease. The BVS has been used in different coronary lesion subsets, such as acute thrombotic lesions, bifurcation lesions, ostial lesions and lesions originating from bypass grafts. However, data about the use of BVS in chronic total occlusions (CTO) are limited. We report our BVS experience for the treatment of CTOs in terms of procedural features and one-year clinical follow-up results...

BACKGROUND: After successful guidewire passage, failure to cross the occluded segment with a balloon is the most common cause of procedural failure in coronary chronic total occlusion (CTO) intervention. We evaluated the safety and efficacy of the balloon-assisted microdissection (BAM) technique for treating these complex balloon-uncrossable lesions. METHODS: We identified consecutive cases treated with BAM for balloon-uncrossable CTOs between January 2012 and February 2015 at two experienced CTO percutaneous coronary intervention (PCI) centers and reviewed their clinical and angiographic characteristics and procedural outcomes...

OBJECTIVES: To evaluate angiographic and clinical results of ZES compared with EES after recanalization of CTOs. BACKGROUND: ZES and EES showed similar clinical results in non-CTO lesions. Whether ZES and EES are also comparable in true CTO lesions (TIMI 0 flow, duration of occlusion of more than 3 months) with a higher risk of restenosis has not been addressed so far. METHODS: 125 patients with successful CTO recanalization via antegrade or retrograde approach were included...

The reverse CART technique provides the potential to modify the retrograde procedure by improving the controlled movement of the retrograde wire and improve the success rates of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). Development of interventricular hematoma is a rare complication of CTO PCI. A 63-year-old man with effort angina with a right coronary artery CTO lesion underwent PCI by retrograde approach from the LAD to a septal branch. A contrast "stain" was demonstrated surrounding the septal collateral channel used for the retrograde approach at the end of the procedure without symptom...
