The success of opening single chronic total occlusion lesions to improve myocardialviabilitytrial (SOS-COMEDY): Study protocol of a prospective multicenter study.

Success of opening single (SOS)-comedy is a prospective multicenter study to compare the improvement in the decrease of myocardial viability by percutaneous coronary intervention (PCI) with that by optimal medical therapy (OMT) alone in patients with chronic total occlusion (CTO) of a single coronary artery.

First prospective multicenter experience with left distal transradial approach for coronary chronic total occlusion interventions using a 7-french glidesheath slender.

to assess the feasibility and safety of the left distal transradial artery (LDTRA) approach using a 7 Fr Glidesheath Slender for chronic total occlusion (CTO) percutaneous coronary interventions (PCIs).

Use of sodium nitroprusside in retrograde percutaneous coronary intervention for chronic total occlusion: A case report.

Chronic total occlusion continues to be a challenging lesion subset for percutaneous coronary intervention.

Late potentials abolition reduces ventricular tachycardia recurrence after ablation especially in higher-risk patients with a chronic total occlusion in an infarct-related artery.

Late potentials (LP) abolition is recognized as an effective strategy for substrate ablation of ventricular tachycardia (VT). The presence of a chronic total occlusion in a coronary artery responsible for a previous myocardial infarction (infarct related artery CTO, IRA-CTO) is emerging as a predictor of ventricular arrhythmias and VT recurrence after ablation. We sought to analyze the effects of LP abolition, focusing on the high-risk sub-group of patients with IRA-CTO.

In-Hospital Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention in Patients With Chronic Kidney Disease.

The effect of chronic kidney disease (CKD) on in-hospital outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study.

Endovascular recanalisation with drug coated balloon for chronic symptomatic middle cerebral artery total occlusion.

The optimal treatment for patients with chronic symptomatic middle cerebral artery (MCA) total occlusion is not well established. In addition to medical therapy, vessel recanalisation with stenting has shown much promise, especially for patients with recurrent ischemic symptoms. Nevertheless, the incidence of symptomatic in-stent restenosis (ISR) is high, and is associated with an unfavorable prognosis. Drug coated balloons (DCBs) have been proven to be effective in treating and preventing ISR. However, the...

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).

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...

Door-to-balloon time and cardiac mortality in acute myocardial infarction by total occlusion of the left circumflex artery.

Acute myocardial infarction (AMI) caused by total occlusion of the left circumflex artery (LCX) can present as non-ST-segment elevation myocardial infarction (NSTEMI). We evaluate whether door-to-balloon time (DBT) is associated with cardiac mortality in patients with total occlusion of the LCX.

Motion-corrected whole-heart PET-MR for the simultaneous visualisation of coronary artery integrity and myocardial viability: an initial clinical validation.

Cardiac PET-MR has shown potential for the comprehensive assessment of coronary heart disease. However, image degradation due to physiological motion remains a challenge that could hinder the adoption of this technology in clinical practice. The purpose of this study was to validate a recently proposed respiratory motion-corrected PET-MR framework for the simultaneous visualisation of myocardial viability (F-FDG PET) and coronary artery anatomy (coronary MR angiography, CMRA) in patients with chronic total ...

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.

Prevalence, Predictors, and Health Status Implications of Periprocedural Complications During Coronary Chronic Total Occlusion Angioplasty.

Contemporary coronary chronic total occlusion (CTO) PCI has been associated with increased success rates. However, the rate of periprocedural complications for hybrid CTO PCI remains incompletely defined. We leveraged the OPEN CTO study to describe the prevalence, predictors, and health status outcomes of complications during contemporary CTO PCI.

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...

Interventional Management of "Balloon-Uncrossable" Coronary Chronic Total Occlusion: Is There Any Way Out?

It has been estimated that coronary chronic total occlusion (CTO) is encountered in 15 to 20% patients referred for coronary angiography (CAG). The success of percutaneous coronary intervention (PCI) of CTO can be attributed to the vast array of hardware that has now become available and also to the vastly enhanced operator expertise. It is however realistic to state that despite the tremendous increase in the rate of success, there then comes a subset of CTO where PCI attempts fail. The reason for such fai...

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.

Long-term clinical outcomes after coronary artery bypass graft versus everolimus-eluting stent implantation in chronic hemodialysis patients.

It remains controversial whether coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI) should be optimized to treat coronary artery disease in patients on chronic hemodialysis (HD). Recently, further refinement of drug-eluting stents, such as the everolimus-eluting stent (EES), has led to marked development in this field. We compared long-term clinical outcomes after CABG versus PCI with EES implantation in patients on chronic HD.

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...

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.

Case 2 / 2018 - Coronary-Cavitary Fistula of Right Ventricular Coronary Artery 5 Years after its Occlusion by Interventional Catheterization.

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...
