Percutaneous treatment of chronic total occlusions (CTO) is one of the major challenges in contemporary interventional cardiology. These lesions are identified in 15% to 30% of all patients referred for coronary angiography. Percutaneous coronary intervention (PCI) of CTOs is technically challenging and requires familiarity with advanced interventional techniques as well as specialty equipment. The choice of strategy and materials is based on clinical features and coronary anatomy; the correct choice is essential to improve the success probability...

BACKGROUND: We aimed to evaluate the mid-term outcomes of a novel thin-strut bioresorbable-polymer sirolimus-eluting stent (BP-SES) in chronic total occlusion (CTO) percutaneous coronary intervention (PCI), as compared with durable-polymer everolimus-eluting stents (EES). METHODS: We compiled a multicenter registry of patients undergoing CTO recanalization followed by BP-SES or EES implantation. The primary endpoint was the incidence of target-lesion failure (TLF, a composite of cardiac death, target-vessel myocardial infarction, and target-lesion revascularization) at one year...

BACKGROUND: The extent of coronary collateral formation is a primary determinant of the severity of myocardial damage and mortality after coronary artery occlusion. Type 2 diabetes mellitus (T2DM) represents an important risk factor for impaired collateral vessel growth. However, the mechanism of reduced coronary collateralization in type 2 diabetic patients remains unclear. METHODS: With the reference to the recent researches, this review article describes the pathogenic effects of T2DM on collateral development and outlines possible clinical and biochemical markers associated with reduced coronary collateralization in type 2 diabetic patients with chronic total occlusion (CTO)...

Coronary chronic total occlusions can be recanalized by expert operators with high success and acceptable complication rates. Developing a procedural plan (using the hybrid or another algorithm) is critical for success. Live case demonstrations appear safe and can be of high educational value. The key factor for achieving good outcomes in chronic total occlusion interventions remains operator expertise. Development of more expert operators will improve the treatment options for this challenging group of lesions and patients...

BACKGROUND: Coronary perforations (CP) have been described as a rare but potentially fatal complication in percutaneous coronary interventions (PCI). Our aim is to compare temporal trends in frequency, management and outcomes of coronary perforations (CP). METHODS: All cases of CP recorded in our prospective institutional percutaneous coronary intervention (PCI) registry from 2003 to 2015 were included. Patients were divided in 2 groups according to the time frame in which the CP occurred: the early period (before 2009, when the chronic total occlusions and primary PCI programs started) and the current period...

During recent years, equipment and techniques for percutaneous coronary intervention (PCI) of chronic total occlusions (CTO) have significantly improved. The retrograde approach remains critical to the improved success of CTO PCI. Currently, the reverse controlled antegrade and retrograde tracking (CART) technique has become the dominant retrograde wire crossing technique. In this article, we propose a standardized terminology and classification of this technique into 3 subtypes: a) conventional reverse CART, that usually involves use of large balloons on the antegrade wire to achieve reentry within the CTO segment; b) "directed" reverse CART which is characterized by small antegrade balloon size and more active, intentional vessel tracking and penetration with a controllable retrograde wire, still within the CTO segment; and c) "extended" reverse CART in which the intimal/ subintimal dissection is extended proximal or distal to the CTO segment, achieving reentry outside the CTO segment...

Percutaneous coronary interventions (PCI) of coronary chronic total occlusions (CTO) increase the risk of high radiation exposure for both the patient and the cardiologist. This study evaluated the maximum dose to the patients' skin (MSD) and the exposure of the cardiologists during CTO-PCI. Moreover, the efficiency of radioprotective drapes to reduce cardiologist exposure was assessed. Patient dose was measured during 31 procedures; dose to the cardiologist's extremities were measured during 65 procedures, among which 31 were performed with radioprotective drapes...
