Collateral circulation develops during the gradual progression of coronary occlusions in order to replace the original artery and supply blood to areas jeopardized by ischemia. However, the relevance of collaterals has remained controversial for many years. Several works have suggested a rapid regression of collaterals after rechanneling of chronic total coronary occlusions, which could render...

Original title: Procedural Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention. A Report From the NCDR (National Cardiovascular Data Registry). Reference: Emanuel S. Brilakis, et al. JACC Cardiovascular Intervention 2015;8:245-53 Chronic total occlusions (CTO) are present in 20% to 50% of pathological coronary angiograms but, even though this percentage has increased in the past years, PCI is performed...
Original title: Predictors of Reocclusion After Successful Drug-Eluting Stent–Supported Percutaneous Coronary Intervention of Chronic Total Occlusion. The Florence CTO PCI Registry. Reference: Renato Valenti et al. J Am Coll Cardiol 2013; article in press. Previous registry data have shown a reduction in mortality rates in patients with successful recanalization of a Chronic Total Occlusion (CTO) compared to patients...
1) Radiation Exposure in Chronic Total Occlusions Even in the hands of experienced operators, rechanneling and angioplasty of a chronic total occlusion (CTO) results in patients and the whole cath lab team receiving high doses of radiation, according to this registry presented at the American Heart Association 2017 Scientific Sessions.

Spanish-Portuguese multicentre CIBELES study (Raul Moreno, Madrid, Spain) compared two drug-eluting stents – an everolimus (Xience V, Abbott Vascular, USA) and a sirolimus-releasing eluting stent (Cypher Select, Cordis Corporation, Miami Lakes, Florida, USA) in the context of total chronic coronary occlusions. With a non-inferiority design, the study randomized 208 patients (1:1), using as the primary...
Chronic total occlusion (CTO) affect up to 20% of patients undergoing angiographic diagnostic tests. During the last two decades, recanalization technique refinement, the development of specific devices and operator skill improvement have elevated procedural success rate up to 90%. However, there are still particular complications such as collateral perforation and access site complications. This is...
Successful rechanneling of a chronic total occlusion (currently around 90%) leads to significant improvement in quality of life and symptom frequency in patients with stable chronic angina compared with optimal medical treatment alone. These results are promising and what we ultimately expected, although symptoms, as a primary endpoint in themselves, are in the eye of...
Dyspnea is one of the most challenging symptoms as regards its assessment and treatment in patients with coronary disease, since it may stem from both cardiac and non-cardiac causes. Patients in whom dyspnea is the sole symptom of coronary disease are at a higher risk of not receiving adequate treatment, and their short- and long-term...
