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.

In recent years, retrograde approach for chronic total occlusions has rapidly evolved, enabling a higher rate of revascularization success. Compared to septal channels, epicardial collaterals tend to ...
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 ...
Inability to cross the occlusion with a guidewire is the most common cause of failure of coronary chronic total occlusion (CTO) interventions. We describe two cases of successful application of the no...
Our aim was to evaluate the effectiveness and safety of CenterCross/MultiCross devices to facilitate the crossing of chronic total occlusions in peripheral arteries.
A 50-year-old female underwent electrophysiology study for paroxysmal palpitation. Panel A represents surface electrocardiogram showing narrow QRS tachycardia with RR alternans and 2:1 VA relation. Pa...
CrossBoss First is a single-blind randomized controlled trial that will randomize 246 patients undergoing clinically-indicated Chronic Total Occlusion Percutaneous Coronary Intervention, t...
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...
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.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
