Gender differences exist in clinical outcomes after routine percutaneous coronary intervention (PCI), but studies reporting such outcomes after chronic total occlusion (CTO) PCI are limited. We assessed the characteristics and outcomes of female patients undergoing CTO PCI. We retrospectively analyzed a dedicated national (United Kingdom) prospective CTO database from 2011 to 2015 for outcomes and characteristics of female patients undergoing CTO PCI (unmatched and propensity matched). Female patients constituted 20...

OBJECTIVES: We examined a contemporary, unselected cohort of patients with coronary chronic total occlusions (CTOs) to determine the impact of CTO revascularization on long-term outcomes. METHODS: We retrospectively assessed the impact of CTO revascularization on clinical outcomes of consecutive patients found to have a CTO during coronary angiography performed at our institution during 2011 and 2012. The primary endpoint was the incidence of a major adverse cardiac event (MACE, defined as a composite of death, myocardial infarction, stroke, and target-vessel revascularization [TVR])...

OBJECTIVE: To examine the presence and localization of lipid-core plaque (LCP) in coronary vessels with chronic total occlusions (CTOs) using near-infrared spectroscopy (NIRS). METHODS: NIRS imaging was performed after guidewire crossing of the occlusion in 15 patients with CTOs. LCP was defined as ≥2 adjacent 2 mm yellow blocks on the block chemogram. We also measured the maximum lipid-core burden index (LCBI) in a 4 mm length of artery (maxLCBI4mm). Large LCP was defined as maxLCBI4mm ≥500...

AIM: Coronary collateral circulation (CCC) has an important impact on cardiovascular prognosis and well-developed CCC is associated with better clinical outcomes. We investigated whether lymphocyte/monocyte ratio (LMR) has an association with CCC in patients with stable coronary artery disease (SCAD). METHODS: The study population consisted of 245 patients with SCAD. Patients were classified into a poor CCC group (Rentrop grades 0/1, n = 87), or good CCC group (Rentrop grades 2/3, n = 158)...

Objective: Previous studies have revealed that the red blood cell distribution width (RDW) was associated with long-term prognosis in patients undergoing percutaneous coronary intervention (PCI). However, they did not exclude patients with anemia. This study, thus, investigated the association between RDW and prognosis in non-anemia patients. Methods: A total of 2 732 patients underwent elective PCI from July 2009 to September 2011 were enrolled in the study. These patients were divided into two groups based on their baseline median RDW levels: low RDW group (RDW<12...

Many animal models have been established for the study of myocardial remodeling and heart failure due to its status as the number one cause of mortality worldwide. In humans, a pathologic occlusion forms in a coronary artery and reperfusion of that occluded artery is considered essential to maintain viability of the myocardium at risk. Although essential for myocardial recovery, reperfusion of the ischemic myocardium creates its own tissue injury. The physiologic response and healing of an ischemia/reperfusion injury is different from a chronic occlusion injury...

BACKGROUND: Multivessel disease (MVD) is a significant risk factor in patients with acute ST-segment elevation myocardial infarction (STEMI). Whether the presence of chronic total occlusion (CTO) poses an additional hazard is still unknown. The objective of this study was to evaluate the impact of CTO on survival in STEMI patients. METHODS: The study group consisted of 836 STEMI patients treated with primary percutaneous coronary intervention (PCI). MVD was diagnosed in 52...

Coronary heart disease is still the leading cause of death in industrialized nations. Even though revascularization strategies such as coronary artery bypass graft surgery, percutaneous coronary intervention and enhanced drug therapy significantly improved the outcome, about 30 % of patients develop chronic heart failure. Ischemic heart disease and heart failure are characterized by an adverse remodeling of the heart, featuring cardiomyocyte hypertrophy, increased fibrosis and capillary rarefaction. Therefore, gene therapeutic approaches for the treatment of heart failure, such as the modulating contractile function or therapeutic neovascularization, seem to be promising...

BACKGROUND: Heavy coronary artery calcification is responsible for stent underexpansion, which is associated with increased in-stent restenosis. Here we report a case in which optical coherence tomography (OCT) demonstrated that the metal component of an underexpanded stent previously implanted in a heavy calcified lesion had been completely removed after ablation with rotational atherectomy. CASE PRESENTATION: An 83-year-old man with exertional angina was referred to our hospital...

BACKGROUND: Chronic total occlusion (CTO) in a noninfarct-related artery (non-IRA) is an independent predictor of mortality in non-ST elevation myocardial infarction (NSTEMI). Mean platelet volume (MPV) is associated with cardiovascular events in NSTEMI. Little is known about the predictors of non-IRA-CTO in patients with NSTEMI. The purpose of this study was to evaluate the relationship between the presence of non-IRA-CTO with MPV level in patients with NSTEMI and multivessel coronary artery disease (MVCAD)...

BACKGROUND: There are few data regarding the procedural and follow-up outcomes of different antegrade dissection/re-entry (ADR) techniques for chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS: We compiled a multicenter registry of consecutive patients undergoing ADR-based CTO PCI at four high-volume specialized institutions. Patients were divided according to the specific ADR technique used: subintimal tracking and re-entry (STAR), limited antegrade subintimal tracking (LAST), or device-based with the CrossBoss/Stingray system (Boston Scientific, Marlborough, MA)...

BACKGROUND: Secondary percutaneous coronary intervention (PCI) in patients with prior coronary artery bypass graft surgery is increasingly common. Graft vessel PCI has higher rates of adverse events compared with native coronary vessel PCI. AIM: To investigate the clinical outcomes of patients with prior CABG who underwent secondary PCI of either a graft vessel (GV), a native coronary vessel (NV) or both graft and native (NG) vessels. METHODS: 220 patients (84% male) who underwent PCI in our institution to either GV (n=89), NV (n=103) or both GV and NV (NG group) (n=28) were studied...

BACKGROUND: Inability to advance a balloon is a well-recognized cause leading to a failure in recanalization of chronic total occlusions (CTOs) despite successfully passing a guidewire. A few techniques and devices have been introduced to facilitate balloon passage, especially the use of Tornus catheter. However, complex manipulation, expensive cost, and availability limit the application of these methods. This study was to evaluate the efficiency and safety of "seesaw balloon-wire cutting" technique in comparison with Tornus catheter for balloon uncrossable CTOs...

Sneddon syndrome (SS) is a rare condition and the diagnosis is made only when other more common disease entities have been excluded. Common manifestations in SS patients include hypertension, coronary artery disease, venous thrombosis, miscarriages, psychiatric disturbances, and arterial and venous thrombotic events. Most patients present in their early 30s with classic neurovascular and dermatologic signs. Currently, the main criteria for the diagnosis of SS include livedo racemosa, focal neurological deficits or evidence of stroke on magnetic resonance imaging, or characteristic vascular alterations seen on biopsy...
