Chronic total occlusion (CTO) represents one of the most challenging lesion subsets faced by the interventional cardiologist. CTO is a common problem, being present in more than 30% of patients undergoing coronary angiography. Over the past 10 years, the success rate of recanalization has increased from approximately 50-85%. Developments in guidewire technology, imaging technique, and coronary devices have contributed to the improved prognosis of patients affected by a CTO lesion. Enhancement in antegrade and retrograde techniques of recanalization also result in improved outcomes. Benefits of CTO recanalization may include symptom relief, decreased need for coronary artery bypass graft surgery, improved left ventricular ejection fraction, and in some cases an improved survival.

A retrograde approach improves the success rate of percutaneous coronary interventions (PCIs) for chronic total occlusions (CTOs).
This study aimed to identify significant lesion features of chronic total occlusions (CTOs) that predict failure of antegrade (A) percutaneous coronary intervention (PCI) using pre-procedure coronary ...
Aims: To assess the incidence and impact on clinical outcomes of subintimal tracking in patients undergoing percutaneous coronary intervention for chronic total occlusion (CTO). Patients at 27 centres...
Antegrade reamed interlocked intramedullary nailing is the treatment of choice forfemoral diaphyseal fractures. More recently, retrograde intramedullary nailing of the femur has been seen as a viable ...
Diabetes mellitus and chronic total occlusions are associated with unfavorable outcome after percutaneous coronary intervention. We sought to assess the clinical and angiographic outcomes of diabetic ...
Primary intracoronary stent placement after successfully crossing chronic total coronary occlusions (CTO) decreases the high restenosis rate at long-term follow-up compared with convention...
Chronically total occlusions (CTO) are difficult to treat and have high risk for restenosis. Although everolimus-eluting stents (EES) are very promising for the treatment of CTOs due to th...
The aim of the study is to assess the safety and efficacy of a Paclitaxel-eluting PTCA-balloon in combination with bare-metal stenting for treatment of chronic total occlusions in native c...
The purpose of this trial is to determine whether aortic manipulation in patients undergoing coronary bypass graft surgery leads to increased incidence of microemboli and subsequent impair...
The purpose of this study is to investigate the potential insults of rotator cuff muscle and the functional recovery of upper extremity function after antegrade nailing of humeral fracture...
Formation or presence of a blood clot (THROMBUS) in a blood vessel within the SKULL. Intracranial thrombosis can lead to thrombotic occlusions and BRAIN INFARCTION. The majority of the thrombotic occlusions are associated with ATHEROSCLEROSIS.
Fiberoptic endoscopy designed for duodenal observation and cannulation of VATER'S AMPULLA, in order to visualize the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (Vater) papillotomy (SPHINCTEROTOMY, ENDOSCOPIC) may be performed during this procedure.
INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.
Incision of Oddi's sphincter or Vater's ampulla performed by inserting a sphincterotome through an endoscope (DUODENOSCOPE) often following retrograde cholangiography (CHOLANGIOPANCREATOGRAPHY, ENDOSCOPIC RETROGRADE). Endoscopic treatment by sphincterotomy is the preferred method of treatment for patients with retained or recurrent bile duct stones post-cholecystectomy, and for poor-surgical-risk patients that have the gallbladder still present.
A subcategory of CHRONIC OBSTRUCTIVE PULMONARY DISEASE. The disease is characterized by hypersecretion of mucus accompanied by a chronic (more than 3 months in 2 consecutive years) productive cough. Infectious agents are a major cause of chronic bronchitis.
