Donor artery stenosis interactions with diastolic blood pressure on coronary collateral flow in type 2 diabetic patients with chronic total occlusion.

We investigated whether and to what extent stenosis of predominant collateral donor artery (PCDA) affects coronary collateral flow in relation to blood pressure (BP) in type 2 diabetic patients with chronic total occlusion (CTO).


Complications of chronic total occlusion percutaneous coronary intervention: Subepicardial hematoma.

A 67-year-old man with coronary artery disease and previous coronary underwent successful Guideliner reverse CART percutaneous coronary intervention of a chronic total occlusion of the right coronary artery. He later developed evidence of myocardial ischemia, and imaging, including angiogram, echocardiogram, and cardiac computed tomography revealing active dye extravasation from the previously normal RV marginal branches, in addition to a large subepicardial hematoma. Despite these dramatic findings, the pa...

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.


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.

Temporal changes in outcomes of women and men undergoing percutaneous coronary intervention for chronic total occlusion: 2005-2013.

Percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) has undergone impressive progress during the last decade, both in strategies and equipment. It is unknown whether technical refinement has translated into improved outcomes in women undergoing CTO-PCI.

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).

Endovascular recanalization for chronic symptomatic intracranial vertebral artery total occlusion: experience of a single center and review of literature.

The optimal treatment of chronic symptomatic total occlusion of the intracranial vertebral artery (ICVA) remains undefined. We report a single-center experience of endovascular recanalization for patients with chronic symptomatic ICVA occlusion who were refractory to medical therapy.

The association of chronic air pollutants with coronary artery spasm, vasospastic angina, and endothelial dysfunction.

We evaluated the effect of chronic exposure to air pollutants (APs) on coronary endothelial function and significant coronary artery spasm (CAS) as assessed by intracoronary acetylcholine (ACH) provocation test.

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.

Antegrade and retrograde approach through the venous graft for treating a chronic total occlusion in a patient with acute coronary syndrome complicated by pulmonary edema.

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 ess...

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.

Mid-term outcomes of chronic total occlusion percutaneous coronary intervention with subadventitial vs. intraplaque crossing: A systematic review and meta-analysis.

Some reports have demonstrated increased risk with subadventitial chronic total occlusion (CTO) crossing, whereas others suggest equipoise between subadventitial and intraplaque crossing techniques. We sought to clarify the effect of subadventitial lesion crossing on mid-term outcomes of CTO percutaneous coronary intervention (PCI).

Coronary intervention for chronic total occlusions: what should the guidelines say?

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...

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.

The impact of successful revascularization of coronary chronic total occlusions on long-term clinical outcomes in patients with non-ST-segment elevation myocardial infarction.

The purpose of this study was to assess the long-term clinical impact of revascularization of coronary concomitant coronary chronic total occlusion (CTO) in patients with Non-ST-segment elevation myocardial infarction (NSTEMI).

Slender transradial iliac artery stenting using a 4.5 French guiding sheath.

We previously reported safety and usefulness of transradial iliac artery stenting using 6 Fr guiding sheath. However, radial artery occlusion was a major limitation of this procedure. We analyzed the safety and utility of slender transradial iliac artery stenting using a 4.5 Fr guiding sheath to prevent radial artery occlusion. We performed transradial iliac artery stenting in left radial artery, using a 4.5 Fr sheath incorporating a shaft length of 110 cm, for 34 lesions in 29 patients. Transradial int...

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.

Incidence, predictors and longer-term impact of troponin elevation following hybrid chronic total occlusion percutaneous coronary intervention.

We examined the incidence of periprocedural cardiac enzyme rise (PCER) [troponin T (TnT) or high-sensivity (hs)TnT >5× the upper limit of normal (ULN)] and periprocedural myocardial infarction (PMI), predictors of PCER and impact of PCER on the longer-term major adverse cardiac events (MACE) following hybrid chronic total occlusion (CTO) percutaneous coronary intervention (PCI).
