Intracoronary imaging in chronic total occlusions

Chronic total occlusion (CTO) intervention constitutes approximately 10–20% of all angioplasty procedures at selected centers. Benefits of CTO revascularization, in addition to relief of angina, include improvement of left ventricular function, reduced risk of major adverse cardiac events and potentially increased survival. Although several techniques, devices and guidewires have been developed...

Antegrade Techniques for Chronic Total Occlusions

By convention, a total obstruction of the coronary artery with no flow at the occluded segment that has been present for at least 3 months is termed as chronic total occlusion or CTO. This is to be distinguished from a sudden occlusion of the coronary artery lumen by a thrombus during an acute myocardial infarction. Percutaneous coronary intervention (PCI) of CTO is increasingly being performed...

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 ...

Microvascular 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...

New Advances in Chronic Total Occlusions.

Coronary chronic total occlusions (CTOs) still represent the greatest technical challenge that interventional cardiologists face. CTOs remain seriously undertreated with percutaneous techniques, far below their prevalence. One reason for the low uptake was the suboptimal CTO percutaneous coronary intervention (PCI) success rates over a long period of time. During the last years, dedicated group...
