REVIEW
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...

During the last 25 years angiotensin-converting enzyme inhibitors spectacularly conquered the field of cardiovascular diseases therapy. Nevertheless, lack of new studies concerning side effects associated with their chronic administration seems to be rather confusing. In our previous research, we proved that the main furnidipines' metabolite (M-2) possess multiple cardioprotective actions. Currently, we compared effects of post-infarction long-term oral treatment with M-2 and captopril on hemodynamic parameters and "ischemic cardiomyopathy" development in rats...

BACKGROUND: Development of the CrossBoss and Stingray devices for antegrade dissection and reentry (ADR) of chronic total occlusions has improved historically suboptimal outcomes. However, the outcomes, safety, and failure modes of the technique have to be studied in a larger patient cohort. This preplanned substudy of the RECHARGE registry (Registry of CrossBoss and Hybrid Procedures in France, the Netherlands, Belgium and United Kingdom) aims to evaluate the value and use of ADR and determine its future position in contemporary chronic total occlusion intervention...

OBJECTIVES: The aim of this study was to compare the ability of conventional versus computed tomography angiography (CTA) to predict procedural success and 30-min wire crossing rates in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) lesions. BACKGROUND: Coronary CTA can be used to assess the morphology of CTO lesions. METHODS: We examined 205 consecutive patients (218 CTO lesions) who underwent coronary CTA pre-PCI...

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...

Trans-ulnar access is a viable alternative approach by experienced operators when the radial and femoral arteries cannot be accessed or used to preserve the contralateral radial artery as possible vascular graft for coronary bypass surgery, hemodynamic monitoring, or shunt creation for hemodialysis. We report a challenging case of ipsilateral trans-ulnar recanalization of a chronic radial artery occlusion, which allowed us to perform a complex trans-ulnar PCI.

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)...

OBJECTIVE: Ghrelin exerts protective effects on cardiovascular system by inhibiting progression of atherosclerosis, supression of vascular inflammation, and stimulating angiogenesis. Thus, the aim of this study was to investigate the effect of serum ghrelin on coronary collateral development and SYNTAX score in patients with severe coronary artery disease. METHODS: Total of 91 patients who had ≥90% stenosis in at least one major coronary artery were prospectively included in this cross-sectional, observational study...

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).

The role of KATP channels in myocardial infarct size-limiting effect of chronic continuous normobaric hypoxia was examined in a rat model based on a 20-min coronary occlusion and subsequent 3-h reperfusion. Rats were adapted to normobaric hypoxia (12% O2) for 21 days. This hypoxia produced a pronounced infarct size-limiting effect, which had been prevented by 0.3 mg/kg glibenclamide, a non-selective inhibitor of entire pool of KATP channels, or 5 mg/kg 5-hydroxydecanoate, an inhibitor of mitochondrial KATP channels...

INTRODUCTION: We examined the impact of proximal vessel tortuosity on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). 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.

A 72-year-old man was referred to our catheterization laboratory 48 hours after a non-ST-segment elevation myocardial infarction. His medical history included coronary artery disease (CAD) (percutaneous coronary intervention of the right coronary artery and chronic total occlusion of the circumflex artery), atrial fibrillation (AF), and chronic kidney disease. An electrocardiogram showed a pre-existent left bundle-branch block and the patient's maximum cardiac troponin concentration was 8.64 µg/L (upper limit of normal: 0...

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...
