Percutaneous Coronary Intervention for Chronic Total Occlusions
I mpasses are common in everyday life. When they occur in coronary arteries as chronic total occlusions (CTOs), they may be difficult to treat. Successful treatment of CTOs sometimes requires a nonconformist approach based on “negative thinking,” which is described in philosophical circles as the mindset that “negates” the possibility of failure and replaces it with the potentiality of success ...
متن کاملMicrovascular dysfunction in chronic total coronary occlusions.
BACKGROUND Microvascular dysfunction is defined as reduced coronary flow reserve in the absence of an epicardial stenosis. This study determined its prevalence and relation to regional myocardial function in chronic total coronary occlusions (TCO). METHODS AND RESULTS After recanalization and stenting of a TCO (duration, >4 weeks) in 42 patients, coronary flow velocity reserve (CFVR) was meas...
متن کاملTransradial approach for percutaneous coronary interventions on chronic total occlusions
The transfemoral approach is the standard approach for performing chronic total occlusion procedures. However, hemorrhagic and vascular entry site complications are known to be reduced by the adoption of the transradial approach. Thus, the transradial approach is gaining interest and, facilitated by the improvement of materials and techniques, will be applied in procedures previously considered...
متن کاملCurrent trends in patients with chronic total occlusions undergoing coronary CT angiography.
OBJECTIVE Data describing the prevalence, characteristics and management of coronary chronic total occlusions (CTOs) in patients undergoing coronary CT angiography (CCTA) have not been reported. The purpose of this study was to determine the prevalence, characteristics and treatment strategies of CTO identified by CCTA. METHODS We identified 23 745 patients who underwent CCTA for suspected co...
متن کاملCurrent considerations regarding the percutaneous revascularization of chronic total coronary occlusions review
Chronic total coronary artery occlusions are commonly encountered, occurring in 15–33% of patients in the angiography suite. Reasons to consider percutaneous coronary revascularization of these lesions include the relief of angina, enhancement of left ventricular ejection fraction and the potential for improved survival. Owing to the complex nature of these lesions, attempts at percutaneous rev...
