Percutaneous coronary intervention (PCI) for coronary artery chronic total occlusion (CTO) is an important treatment to be used in conjunction with non-CTO PCI, coronary artery bypass grafting, and optimal medical therapy to achieve complete revascularization in patients with coronary artery disease.
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...
Diabetes mellitus (DM) is a major predictor of cardiovascular morbidity and mortality. However, there are limited data on the impact of DM in patients who have chronic total occlusion (CTO) lesion on long-term outcomes.
In-hospital outcomes of acute myocardial infarction (AMI) with cardiogenic shock (CS) were still not satisfactory even in the primary percutaneous coronary intervention (PCI) era. The aim of this study was to compare in-hospital outcomes of AMI with CS caused by right coronary artery (RCA) occlusion vs. left coronary artery (LCA) occlusion. Consecutive 894 AMI patients from January 2010 to March 2015 were screened for inclusion. A total of 114 AMI patients with CS were included as the final study population...
In-stent chronic total occlusion (CTO) represents a challenging lesion subset for percutaneous coronary intervention (PCI), and although a true-to-true lumen crossing is the first-line strategy, a subadventitial approach may become necessary. Here we describe a case of successful in-stent right coronary artery CTO-PCI performed with subadventitial crossing, crushing of the occluded stents, and advancement of a mother-and-child catheter to the distal right coronary artery through the subadventitial space to ...
We sought to examine contemporary perspectives and practices on chronic total occlusion (CTO) percutaneous coronary intervention (PCI).
Percutaneous coronary intervention (PCI) of total chronic total occlusion (CTO) still remains a major challenge in interventional cardiology. There is only insignificant knowledge reported in the literature about age differences in CTO recanalization. We analyzed in this study the issue of the impact of age on procedural characteristics, complications and short-term outcome.
Myocardial infarction (MI) is an extremely common cause of chest pain. MI can be acute with ST elevation (STEMI) or non-STEMI (NSTEMI). Coronary artery spasm can be severe enough to cause occlusion of the coronary arteries particularly with an exaggerated response in regions of coronary atheroma and plaque ulceration. It is not uncommon for coronary spasm to be mistaken with acute thrombotic occlusion of the coronary artery. We describe a case of a 42-year old man with known cardiac risk factors presents wi...
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.
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.
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.
The aim of this study was to identify positive and negative predictors of technical and clinical success for percutaneous coronary intervention (PCI) of chronic total occlusions (CTO).
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...
Percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) may be facilitated by projection of coronary computed tomography angiography (CTA) datasets in the catheterization laboratory. There is no data on the feasibility and safety outcomes of CTA-assisted CTO PCI using a wearable augmented-reality glass.
The study was aimed at revealing risk factors for progression of atherosclerosis in the shunted coronary artery in the remote period following coronary artery bypass grafting. Our prospective study included a total of 292 patients having endured coronary artery bypass grafting. All patients were divided in two groups depending on the type of the bypass grafts used: either autoarterial shunts (Group 1) or autovenous grafts (Group 2). We thus assessed a total of 516 autoarterial grafts and 257 autovenous graf...
The optimal strategy to treat bifurcation lesions (BFLs) in a percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) remains unknown.
There is little evidence on the optimal strategy for bifurcation lesions in the context of a coronary chronic total occlusion (CTO). This study compared the procedural and mid-term outcomes of patients with bifurcation lesions in CTO treated with provisional stenting vs 2-stent techniques in a multicenter registry.
Chronic total occlusions (CTOs) are routinely encountered during coronary angiography, but subsequent revascularization rates are low. This has likely been driven by a historical belief that there is minimal clinical benefit and poor success rates with a percutaneous coronary intervention (PCI). However, in the current era, with the development of new techniques and tools, experienced operators can perform CTO-PCI successfully in the majority of patients. The current indications and benefit of CTO-PCI remai...
Long-term patient and kidney survival after coronary artery bypass grafting, percutaneous coronary intervention, or medical therapy for patients with chronic kidney disease: a propensity-matched cohort study.
Revascularization in patients with chronic kidney disease (CKD) and coronary artery disease (CAD) is often deferred because of concern over progression of renal failure.
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).
Congenital atresia of the left main coronary ostium is a rare coronary anomaly presenting in adulthood. A 48-year-old man presented with unstable angina. Coronary angiography showed an absent left coronary ostium with a super-dominant right coronary artery retrogradely filling the left system. Computed tomography-angiography with 3-dimensional reconstruction confirmed the absence of the left main coronary artery. In view of ongoing chest pain, the patient was offered coronary artery bypass surgery. Total ar...
The objective of this study was to evaluate the haemodynamic patterns in each anastomosis fashion using a computational fluid dynamic study in a native coronary occlusion model.
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...
