Impact of chronic total occlusion in a non-infarct-related coronary artery on myocardial injury assessed by cardiac magnetic resonance imaging and prognosis in ST-elevation myocardial infarction.

Mechanisms underlying increased mortality in patients with chronic total occlusion (CTO) of a non-infarct-related artery (non-IRA) are unknown. Cardiac magnetic resonance (CMR) is uniquely suited to provide important mechanistic and pathophysiological information on myocardial damage and reperfusion injury. Aim of this study was to investigate the association of a CTO in a non-IRA with myocardial damage assessed by CMR in patients with ST-elevation myocardial infarction (STEMI).

Radiofrequency ablation of a middle cardiac vein inserted accessory pathway resulting in posterolateral coronary artery occlusion: A case report.

Posteroseptal accessory pathways account for 34.5% of the total. Of these, 36% are located within the coronary sinus (CS). Its ablation requires technical alternatives to avoid damage to surrounding tissues, especially branches of the right coronary artery.

Relationship of Autophagy and Apoptosis with Total Occlusion of Coronary Arteries.

BACKGROUND The primary aim of this study was to evaluate the level of autophagy and apoptosis enzymes in patients with coronary artery disease (CAD). Furthermore, we investigated the role of autophagy and apoptosis in the progression of coronary collateral and coronary total occlusion (TO). MATERIAL AND METHODS We enrolled 115 patients in this prospective, observational, controlled study, who were categorized into 3 groups as follows: group 1, patients with chronic TO (n=49); group 2, patients with acute TO...

Impact of chronic total occlusion on ventricular arrhythmia and mortality in ischaemic cardiomyopathy patient with implantable cardiac defibrillator: a meta-analysis.

Recent studies suggested that chronic total occlusion of the coronary artery increased risk of ventricular arrhythmia (VA) and all-cause mortality in ischaemic cardiomyopathy (ICM) patient who underwent implantable cardiac defibrillator (ICD) implantation. We aim to demonstrate an association between a presence of CTO and poor cardiovascular outcome in ICD implanted ICM patients.

The atherogenic index of plasma and its impact on recanalization of chronic total occlusion.

The plasma-derived atherogenic index (AIP) is associated with an increasing risk for cardiovascular diseases. Whether an increased AIP may predict the complexity of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO), according to available research, has never been investigated before.

Chronic total coronary occlusion treated with excimer laser coronary atherectomy: a case report.

Association of lipoprotein(a) and coronary artery disease in 1003 patients with stage 3-5 chronic kidney disease undergoing coronary angiography.

Lipoprotein(a) [Lp(a)] is considered a risk factor for cardiovascular disease. However, the role of Lp(a) in chronic kidney disease (CKD) patients is not well understood. The aim of this study was to evaluate the association between Lp(a) levels and the presence of coronary artery disease (CAD) and the severity of coronary artery stenosis (CAS) in patients with stage 3-5 CKD.

Distal Thrombectomy for Acute Anterior Circulation Stroke with Chronic Large Vessel Occlusion.

Endovascular therapy has been increasingly recommended for the treatment of acute ischemic stroke with large vessel occlusion of the anterior circulation. However, occlusions of the distal cerebral artery are not uncommon and may cause clinical deficits, especially when combined with ipsilateral chronic large vessel occlusion. Therefore, in this patient population, the recognition of chronic occlusion and recanalization of the distal occlusive artery might be of great value for flow compensation.

Percutaneous Coronary Intervention in Chronic Total Occlusion.

Percutaneous coronary intervention in chronic total occlusion is a rapidly evolving area, being considered the last frontier of interventional cardiology. In recent years, the development of new techniques and equipment, as well as the training of specialized personnel, increased their success rates, making it the most predictable procedure available. Although the number of randomized and controlled studies is still limited, results from large multicentered registries allow us to safely offer this intervent...

Contrast-Induced Nephropathy After Percutaneous Coronary Intervention for Chronic Total Occlusion Versus Non-Occlusive Coronary Artery Disease.

Contrast volume is associated with the incidence of contrast-induced nephropathy (CIN), and CIN risk could be particularly high in chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Our aim was to evaluate the incidence of CIN in patients who underwent CTO versus non-CTO PCI. All PCIs performed at our institution from January 2012 to December 2016 were included in this study. CIN was defined as an increase of ≥0.3 mg/dl or ≥50% from baseline within 72 hours. Multivariable logistic r...

Flowmetric and angiographic predictors of occlusion of coronary bypass grafts.

The study was aimed at assessing remote (up to 42 months) results of coronary artery bypass grafting (CABG) and revealing flowmetric and angiographic predictors of coronary bypass graft occlusion.

Nonrobotic Total Endoscopic Coronary Artery Bypass Grafting: A Proof-of-Concept Study in 20 Patients.

At present, minimal invasive direct coronary artery grafting is the least invasive nonrobotic surgical approach to revascularize the left anterior descending artery with the left internal mammary artery. Total endoscopic coronary bypass grafting is performed with the help of a telemanipulator ("robot"). A prospective proof-of-concept study was initiated to investigate a nonrobotic total endoscopic coronary bypass grafting approach.

Repeat stent implementation for recanalization of the proximal right coronary artery: a case report.

A stent in a false lumen is a common cause of stent occlusion after coronary percutaneous coronary artery intervention therapy, particularly in the culprit lesion of acute myocardial infarction. Here, we present an unusual case of successful recanalization of the proximal right coronary artery with implementation of another stent to crush the previous stent in the false lumen.

Impact of the angiographic burden on the incidence of out-of-hospital ventricular fibrillation in patients with acute myocardial infarction.

Ventricular fibrillation (VF) is a catastrophic complication of spontaneous (type 1) acute myocardial infarction (AMI). This study sought to clarify the angiographic coronary characteristics related to out-of-hospital VF in AMI patients. We retrospectively reviewed 464 consecutive cases of suspicious AMI, including type 1 AMI, with or without out-of-hospital VF. In addition to patient demographics, proximal left coronary artery (LCA) disease, multivessel disease (MVD), and chronic total occlusion (CTO) were...

High-sensitivity Cardiac Troponin T as a Predictor of Acute Total Occlusion in Patients with Non-ST-segment Elevation Acute Coronary Syndrome.

A large percentage of patients with non-ST-segment acute coronary syndrome (NSTE-ACS) present with acute total occlusion (TO) of some major epicardial vessel that does not generate electrocardiographic changes. Ongoing research into the methods of accurately predicting acute TO have not yielded great success. The present study aimed to evaluate the predictive value of high-sensitivity cardiac troponin T (hs-cTnT) for the presence of acute TO of the culprit artery in patients with NSTE-ACS.

Clinical usefulness of the angle between left main coronary artery and left anterior descending coronary artery for the evaluation of obstructive coronary artery disease.

A wider angle between the left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX) has been suggested to induce plaque formation in the arterial system via changes in shear stress. However, the relationship between the left main coronary artery (LM)-LAD angle and LAD stenosis has not been investigated. Therefore, we aimed to evaluate the associations between the LM-LAD and LAD-LCX angles and LAD stenosis.

Use of chronic total occlusion percutaneous coronary intervention techniques for treating acute vessel closure.

Acute vessel closure due to dissection is a known complication of percutaneous coronary intervention and can be challenging to treat, especially if guidewire position is lost. Re-entering into the distal true lumen is commonly done during chronic total occlusion interventions, as part of antegrade dissection strategies. We report two cases of acute vessel closure and guidewire position loss in which the Stingray LP system was successfully used to advance a guidewire into the distal true lumen and recanalize...

Fistulae ligation and left main artery ligation for a bilateral giant coronary arterial fistulae-related aneurysm.

Bilateral congenital coronary artery fistulae complicated with a giant coronary artery aneurysm is a very rare condition. A coronary artery aneurysm is a coronary artery dilatation that exceeds the diameter of normal adjacent segments or the diameter of the patient's largest coronary vessel by 1.5 times. The complications associated with a coronary artery aneurysm include thrombosis, embolization, rupture, vasospasm, congestive heart failure and infectious endocarditis. We report on a 63-year-old woman pres...
