BACKGROUND: There are only limited studies reporting clinical outcomes after bioresorbable vascular scaffold (BVS; Absorb; Abbott Vascular, Santa Clara, CA) implantation for coronary chronic total occlusions (CTO). The aim of this study was to evaluate the real-world feasibility and safety of BVS implantation for the treatment of CTO. METHODS AND RESULTS: We retrospectively evaluated CTO cases treated with BVS from a multicenter registry. The primary end point was target lesion failure defined as a composite of cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization...

BACKGROUND: The impact of hyperoxia on exercise limitation is still incompletely understood. OBJECTIVES: We investigated to which extent breathing hyperoxia enhances the exercise performance of healthy subjects and which physiologic mechanisms are involved. METHODS: A total of 32 healthy volunteers (43 ± 15 years, 12 women) performed 4 bicycle exercise tests to exhaustion with ramp and constant-load protocols (at 75% of the maximal workload [Wmax] on FiO2 0...

This case report describes a successful percutaneous coronary intervention (PCI) of a severely calcified aorto-ostial chronic total occlusion (CTO) of the right coronary artery (RCA). The lesion was treated by a retrograde approach implementing long spiral subintimal wire tracking and final coronary stenting creating a subintimal neo-luminal helix around the natively occluded RCA. After 6 months of follow-up valuable angiographic results were proven.

: Many low- and middle-income countries lack the resources and services to manage cancer, from screening and diagnosis to radiation therapy planning, treatment and quality assurance. The challenges in upgrading or introducing the needed services are enormous, and include severe shortages in equipment and trained staff. In this symposium, we will describe examples of technology and scientific research that have the potential to impact all these areas. These include: (1) the development of high-quality/low-cost colposcopes for cervical cancer screening, (2) the application of automated radiotherapy treatment planning to reduce staffing shortages, (3) the development of a novel radiotherapy treatment unit, and (4) utilizing a cloud-based infrastructure to facilitate collaboration and QA...

OBJECTIVE: This study evaluated long-term results following successful endovascular therapy (EVT) for chronic total occlusion (CTO) below the knee (BTK) using the retrograde approach after a failed antegrade approach. METHODS: Nineteen patients (19 limbs) with critical limb ischemia (CLI) who underwent successful EVT for BTK-CTO using the retrograde approach after a failed antegrade approach during 2010-2014 were studied. RESULTS: Mean duration of the follow-up period was 25...

OBJECTIVE: Treatment of chronic total occlusion (CTO) with everolimus-eluting bioresorbable vascular scaffold (BVS) is safe and effective at short-term follow-up (FU). The current study investigated clinical and angiographic outcomes after treatment of CTO with BVS at >1 year. METHODS: Thirty patients who underwent successful recanalization of 35 CTOs were included in this study. Quantitative coronary angiography (QCA) was performed at median FU period of 402 days...

AIMS: We sought to investigate the clinical impact of chronic total occlusion (CTO) in non-infarct-related artery (IRA) on long-term cardiovascular outcomes in patients with ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS: Among 5429 patients enrolled in the CREDO-Kyoto AMI registry, the current study population consisted of 2045 STEMI patients with multi-vessel disease (MVD) who underwent primary PCI within 24 hours after the symptom onset. The cumulative 5-year, 30-day and 30-day-to-5-year incidences of all-cause death were all significantly higher in the CTO group than in the non-CTO group (37...

INTRODUCTION: We aimed to assess if ranolazine would improve angina symptoms among patients with documented myocardial ischemia. METHODS: Eligible subjects had chronic stable angina and at least one coronary stenosis with fractional flow reserve (FFR) ≤0.80 or at least one chronic total occlusion (CTO) without attempted revascularization. Subjects were randomized to oral ranolazine 500 mg twice daily for 1 week, then ranolazine 1000 mg twice daily for 15 weeks versus matching placebo...

BACKGROUND: The presence of a bifurcation (BL) in the context of a coronary chronic total occlusion (CTO) represents an additional difficulty. This study analyzes the incidence of BLs in CTO recanalization, the treatment, predictors of bifurcation technical success and their clinical impact. METHODS AND RESULTS: BLs with a side branch (SB) ≥2.0mm located proximally, distally or within the occluded segment were observed in 130 (33%) of 391 CTO. Provisional stenting was the strategy more frequently used (94%)...

BACKGROUND: Percutaneous coronary intervention (PCI) of total chronic coronary occlusion (CTO) still remains a major challenge in interventional cardiology. To predict the probability of a successful intervention different scoring systems are available. We analyzed in this study the validity of two scoring systems, the Japanese CTO score (J-CTO score) and the newly developed Clinical and Lesion-related score (CL Score). METHODS: Between 2012 and 2015 we included 379 consecutive patients...

BACKGROUND: Collateral filling of chronic total occlusion (CTO) segments is considered to affect hemodynamic stability in primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) with CTO, however its value as a prognostic indicator for mortality is uncertain. The present study examined the relationship between collateral filling of CTO segments and short-term mortality in patients with STEMI with a comorbid CTO lesion. METHODS: Among 829 STEMI patients who underwent primary PCI, 74 patients with CTO were identified...

OBJECTIVES: Community Treatment Order (CTO) is a legal regime that obliges patients suffering mental disorder to adhere to treatment in the community and allows for a swift admission to hospital if necessary. Study aims were to: (i) determine CTO frequency in a large representative sample of first episode psychosis (FEP) patients; (ii) compare the characteristics of patients with or without CTO before entry, during treatment and at discharge from an early psychosis program. METHODS: Information on 660 patients treated at the Early Psychosis Prevention and Intervention Centre (EPPIC) between 1998 and 2000 was collected from medical files...

OBJECTIVES: To study the long-term outcomes of rotational atherectomy (RA) for chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: There is little evidence on the incidence, procedural results and long-term outcomes of RA for CTO PCI. METHODS: This registry included data from consecutive patients undergoing CTO PCI at four specialized centers. Major adverse cardiac events (MACE: cardiac death, target-vessel myocardial infarction and ischemia-driven target-vessel revascularization) on follow-up were the primary endpoint...

Recovery is a crucial concept in the mental health field. The research of recovery is split into the categories of personal, social and clinical recovery. The purpose of this study was to explore the fragmented concept of recovery in light of assertive community treatment (ACT) in Norway. The study has a mixed methods design with a pragmatic approach. The Questionnaire about the Process of Recovery and open-ended questions posed to 70 participants from 12 ACT teams in Norway, gathered by the "Users interview users" method, are combined with interviews or focus groups with eight of these participants...

BACKGROUND: The recanalization success rate of chronic total occlusion (CTO) percutaneous coronary interventions (PCI) can be increased by the retrograde approach; however, the long-term outcome of patients undergoing retrograde procedures is unknown.

AIMS: Limited data exist on the treatment and outcomes of patients with chronic total occlusions due to in-stent restenosis (CTO-ISR). We sought to evaluate results and clinical outcomes in percutaneous interventions over CTO-ISR. METHODS AND RESULTS: Registry in 16 centers involving consecutive patients undergoing attempt of percutaneous intervention over CTO-ISR. A total of 233 patients were included, 192 (82.4%) with successful acute result. Success rate was significantly lower in patients with: lesion in circumflex artery, ostial lesion, J score > 3 and no femoral access...
