BACKGROUND Superficial femoral artery chronic total occlusion (SCTO) is a common type of peripheral arterial disease (PAD). Endovascular therapy is a treatment approach that has a poor long-term success rate in this group. The aim of this study was to compare the mid-term results of two different uses of nitinol stents in long SCTO lesions (>100 mm): the use of one long stent or two shorter stents. MATERIAL AND METHODS Of 154 patients who underwent percutaneous infrainguinal interventions from 2011 to 2014, a total of 170 CTO lesions were selected for this retrospective study analysis...

Hemal Bhatt, Sean Janzer, Jon C George
Coronary chronic total occlusion (CTO) intervention remains one of the most challenging domains in interventional cardiology. Due to the technical challenges involved and potential procedural complications, CTO percutaneous coronary intervention (PCI) attempt and success rates remain less than standard PCI. However, the use of several adjunctive tools such as intravascular ultrasound, optical coherence tomography, rotational atherectomy, orbital atherectomy, excimer laser coronary atherectomy and percutaneous left ventricular assist device may contribute to improved CTO PCI success rates or provide better hemodynamic assessment of CTO lesion (i...

We investigated the relationship between the neutrophil-lymphocyte ratio (NLR) and in-stent restenosis (ISR) in patients with femoropopliteal chronic total occlusions (CTOs). The study enrolled 180 patients who had undergone successful stenting treatment for femoropopliteal CTO. Patients with ISR were subsequently classified into 2 groups: early-ISR (within 1 year) and late-ISR (after 1 year). The clinical characteristics, angiographic data, and follow-up data were recorded. The baseline NLR was significantly higher in the early-ISR group than that in the non-ISR group [3...

BACKGROUND: Following the development of breakthrough techniques for percutaneous coronary intervention (PCI) in the treatment of chronic total occlusions (CTO), the initial success rate of PCI in CTO lesions (CTO-PCI) has improved; however, there are few reports regarding the effects of successful CTO revascularization on long-term mortality in Japan. The aim of this study was to compare the long-term clinical outcomes of patients with successful versus failed CTO recanalization and to identify related factors...

The aim of this review is to highlight the technical details and the scientific data on percutaneous coronary interventions (PCIs) in chronic total occlusion (CTO) performed by transradial approach (TRA). Transfemoral approach (TFA) is commonly regarded as the standard for CTO PCI, but there are a growing number of CTO recanalization procedures performed by TRA. We discuss the relevant technical details to approach a CTO by transradial access, especially the compatibility of various CTO recanalization techniques with specific guiding catheter sizes...

OBJECTIVE: To compare the use of a dose mapping software to Gafchromic film measurement for a simplified peak skin dose (PSD) estimation in interventional cardiology procedure. METHODS: The study was conducted on a total of 40 cardiac procedures (20 complex coronary angioplasty of chronic total occlusion (CTO) and 20 coronary angiography and coronary angioplasty (CA-PTCA)) conducted between January 2014 to December 2015. PSD measurement (PSDFilm) was obtained by placing XR-RV3 Gafchromic under the patient's back for each procedure...

OBJECTIVES: The aim of this study was to develop a hybrid approach-specific model to predict chronic total coronary artery occlusion (CTO) percutaneous coronary intervention success, useful for experienced but not ultra-high-volume operators. BACKGROUND: CTO percutaneous coronary intervention success rates vary widely and have improved with the "hybrid approach," but current predictive models for success have major limitations. METHODS: Data were obtained from consecutively attempted patients from 7 clinical sites (9 operators, mean annual CTO volume 61 ± 17 cases)...

Retrograde dissection re-entry can cause pericardial trauma of sufficient degree to lead to the development of an auto-immune postpericardial injury syndrome. Clinical suspicion for this condition should be high in the event of fever, symptoms, pericardial/pleural effusion, and pleuritic chest pain following chronic total occlusion (CTO) Post cardiac injury syndromes (PCI).

PURPOSE: To describe the feasibility and safety of an anterolateral popliteal puncture technique as a retrograde access to chronic total occlusions (CTOs) in the femoropopliteal segment. METHODS: Twenty consecutive patients (mean age 75.1±10.9 years; 13 women) with symptomatic femoropopliteal occlusive disease underwent endovascular therapy via a retrograde access using the anterolateral popliteal puncture technique. With the patient supine, the P3 segment of the popliteal artery was accessed with a sheathless technique intended to provide minimally invasive access...

METHODS: The baseline clinical and angiographic characteristics and procedural outcomes of 1618 consecutive CTO-PCIs performed between 2012 and 2016 at 14 United States centers in 1589 patients were reviewed. RESULTS: Mean patient age was 65.3 ± 10.0 years and 85% were men. Moderate/severe proximal vessel tortuosity was present in 35...

OBJECTIVES: The present study examined the association between Multicenter CTO Registry in Japan (J-CTO) score in predicting failure of percutaneous coronary intervention (PCI) correlating with the estimated duration of chronic total occlusion (CTO). BACKGROUND: The J-CTO score does not incorporate estimated duration of the occlusion. METHODS: This was an observational retrospective study that involved all consecutive procedures performed at a single tertiary-care cardiology center between January 2009 and December 2014...

Total occlusion of a coronary artery for more than 3 months is defined as chronic total occlusion (CTO). The goal of this study was to develop a risk score in predicting failure or success during attempted percutaneous coronary intervention (PCI) of CTO lesions using antegrade approach. This study was based on retrospective analyses of clinical and angiographic characteristics of CTO lesions that were assessed between February 2012 and February 2014. Success rate was defined as passing through occlusion with successful stent deployment using an antegrade approach...

BACKGROUND: Due to ischemic time delays from the chest pain occurrence in acute STEMI, prompt recruitment collaterals (PRCCs) to infarct related artery (IRA) are the major protective structures during this period. So, we aimed to investigate the clinical significance and determinants of PRCCs in acute STEMI patients. METHODS: A total of 1375 consecutive acute STEMI patients were prospectively enrolled in the study. The patients were divided in two groups, according to PRCCs to IRA; Rentrop≤1 were defined as inadequate collateral development (ICD) group and Rentrop≥2 defined as adequate collateral development (ACD) group...

Objective: To explore the relationship between fragmented QRS complex(fQRS) and coronary collateral circulation(CCC) in patients with chronic total occlusion(CTO)lesion without prior myocardial infarction. Methods: This retrospective study analyzed 238 consecutive patients with CTO lesion in one of the major coronary arteries from May 2014 to October 2015 in our department. Patients were divided into poor CCC group (grade 0 and 1, 58 cases) and good CCC group(grade 2 and 3, 180 cases) based on Rentrop's classification of CCC...

The aim of this study was to evaluate the feasibility and efficacy of the Guidezilla guide extension catheter in a reverse controlled antegrade and retrograde subintimal tracking (CART) technique for chronic total occlusion (CTO) recanalization.We retrospectively collected 80 CTO cases using reverse CART technology from January 2015 to October 2015 and 20 CTO cases using Guidezilla reverse-CART technology from October 2015 to March 2016. Guidezilla was applied in cases when it was difficult to advance a retro-guidewire through an occlusion segment into the antegrade guide catheter...

OBJECTIVES: Using intravascular ultrasound (IVUS), the authors compared outcomes by observed wire position (intraplaque vs. subintimal) achieved during successful chronic total occlusion (CTO) lesion treatment. BACKGROUND: Recent successes in CTO percutaneous coronary intervention (PCI) have used both intraluminal and subintimal wire tracking to improve procedural success. IVUS may be used to determine the course of wire tracking after crossing a CTO. METHODS: From March 2014 to March 2016, data were collected into a single-center database from 219 patients undergoing CTO PCI with concomitant IVUS imaging...
