Black carbon and total organic carbon (TOC) along with organochlorines (OCs) were analyzed in soils from four sampling zones of Lesser Himalayan Region based on source proximity/anthropogenic influences along the altitude. CTO-375 method was used for BC analysis while OCs were analyzed by GC-MS/MS system. BC and TOC ranged between 0.16-1.77 and 6.8-41.3 mg g(-1) while those of OCPs and PCBs ranged between 0.69 and 5.77 and 0.12-2.55 ng g(-1), respectively. ∑DDTs were the dominant (87.9%) among OCPs while tri- and tetra- (65...

Patient selection for and predicting clinical outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) remain challenging. We hypothesized that both J-CTO (Multicenter Chronic Total Occlusion Registry of Japan) and PROGRESS CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention) scores will predict not only angiographic success but also long-term clinical outcomes of the patients who underwent PCI of CTO. Of 325 CTO PCIs performed at 2 Emory University hospitals from January 2012 to August 2015, 249 patients with complete baseline clinical, angiographic and follow-up data, were included in this analysis...

OBJECTIVES: Percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) has historically been associated with higher event rates during follow-up. The hybrid algorithm and contemporary wiring and dissection re-entry (DR) techniques can potentially improve long-term outcomes after CTO-PCI. This study assessed the long-term clinical outcomes of the hybrid CTO practice, when applied by operators with varying experience levels. METHODS: We examined the 1-year clinical events after hospital discharge of the RECHARGE population, according to technical outcome and final technique...

BACKGROUND: Retrograde percutaneous coronary intervention (PCI) of native coronary artery chronic total occlusion (CTO) via left internal mammary artery (LIMA) graft has received limited study. METHODS AND RESULTS: We compared the clinical and procedural characteristics and outcomes of retrograde CTO-PCI through LIMA grafts vs other conduits in a contemporary multicenter CTO registry. The LIMA was used as the collateral channel in 20 of 990 retrograde CTO-PCIs (2...

BACKGROUND: Bioresorbable vascular scaffolds (BVS) have been heralded with potential benefits that are especially desired in long lesions, including chronic total occlusions (CTOs). Procedural feasibility and mid-term outcomes of BVS in CTOs have been reported. However, there is still a paucity of data regarding the vascular and healing response to BVS in CTOs evaluated by optical coherence tomography (OCT). METHODS: This study included prospectively 21 patients who had a CTO lesion treated with a BVS...

BACKGROUND: Nowadays, due to advanced techniques and well-trained interventionists in catheter labs, new scientific research has shown percutaneous coronary intervention (PCI) to be a safe treatment procedure in patients with chronic total occlusion (CTO). However, no study has systematically compared PCI outcomes in CTO patients with versus without type 2 diabetes mellitus (T2DM). Therefore, through this meta-analysis we aimed to systematically solve this issue. METHODS: Between September 2016 and June 2017, the Cochrane Database of Randomized Trials, EMBASE, and MEDLINE databases were carefully searched for publications comparing PCI outcomes in CTO patients with versus without T2DM...

Glucose metabolism status may play a predictive role in the severity of the complications among patients with type 2 diabetes mellitus (DM). However, few studies have focused on the prognostic value of glycosylated hemoglobin (HbA1c) and Homeostatic Model Assessment 2 for Insulin Resistance (HOMA2-IR) in patients with DM, non-ST-segment elevation infarction (NSTEMI), and single concomitant chronic total occlusion (CTO) following primary percutaneous coronary intervention (PCI). Short- and long-term prognostic value of HbA1c and HOMA2-IR in patients with DM with NSTEMI and single CTO who received primary percutaneous transluminal coronary intervention (pPCI)...

BACKGROUND: Chronic kidney disease (CKD) adversely affects outcomes in patients with coronary artery disease. Data on the impact of renal impairment on prognosis of patients undergoing percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) are scarce. METHODS: A total of 2002 patients undergoing CTO PCI were stratified according to baseline renal function (group 1: estimated glomerular filtration rate [eGFR] ≥ 90 ml/min/1.73 m(2), group 2: 60 to 89 ml/min/1...

OBJECTIVES: A single-centre, observational study was performed in order to investigate the relationship between anemia and outcomes after percutaneous coronary intervention (PCI) for chronic total occlusion (CTO). BACKGROUND: Anemia has been identified as adverse predictor in patients with coronary artery disease undergoing coronary revascularization. Data on the impact of anemia on outcomes in patients undergoing PCI for CTO lesions are lacking. METHODS: A total of 1,964 patients undergoing CTO PCI were stratified according to the presence/absence of anemia (hemoglobin of <13 g/dl for men and <12 g/dl for women)...

OBJECTIVES: Few studies have evaluated the relationship of diabetes with technical success and periprocedural complications, and no studies have compared patient-reported health status after chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in patients with and without diabetes. BACKGROUND: CTOs are more common in patients with diabetes, yet CTO PCI is less often attempted in patients with diabetes than in patients without. The association between diabetes and health status after CTO PCI is unknown...

Although the hybrid chronic total occlusion (CTO) algorithm had many excellent recommendations, there has been infrequent adoption in the Asia Pacific region. The Asia Pacific CTO club propose an algorithm for case selection based on the Japan-CTO score and a new CTO algorithm, which is applicable globally. This algorithm allows for differing skill sets and equipment availability and contains practical teaching for CTO percutaneous coronary intervention. Similar to the hybrid algorithm there are 3 main questions that determine whether the primary approach is antegrade or retrograde: 1) is there proximal cap ambiguity; 2) is the distal vessel of poor quality; and 3) are there interventional collaterals present...

Antegrade and retrograde dissection/re-entry techniques are frequently utilized in contemporary CTO PCI, especially for complex lesions. One-year outcomes with modern dissection/re-entry techniques appear favorable and comparable with those achieved after intraplaque crossing, supporting their increased use. Randomized data on the procedural safety, efficiency, and long-term outcomes of subadventitial CTO PCI techniques are needed.

Chronic total occlusions (CTO) are common in patients with symptomatic peripheral arterial disease. Endovascular CTO intervention remains a challenging endeavor for interventionalists, but is being increasingly considered as a plausible alternative to surgical revascularization, even for complex CTO lesions. We review common endovascular techniques using antegrade, retrograde and transcollateral approaches in femoropopliteal CTO intervention. In addition, we review the current literature on the utility, efficacy, and safety of novel crossing and re-entry devices in femoropopliteal CTO interventions...
