Crossing Total Occlusions: Navigating Towards Recanalization
Chronic total occlusions (CTOs) represent the "last frontier" of percutaneous interventions. The main technical challenges lies in crossing the guidewire into the distal true lumen, which is primarily due to three problems: device buckling during initial puncture, inadequate visualization, and the inability to actively navigate through the CTO. To improve the success rate and to identify future...
متن کاملEndovascular Crossing of Chronic Total Occlusions Using an Impulse: An Explorative Design Study
In this study we investigated whether exerting an impulse on a Chronic Total Occlusion (CTO) improves the success rate of CTO crossing as compared to the currently used method of statically pushing the guidewire against the CTO. A prototype (Ø2 mm) was developed that generates translational momentum using a spring-loaded indenter and converts it to an impulse during impact. Mechanical performan...
متن کاملPercutaneous Recanalization of Coronary Chronic Total Occlusions: Current Devices and Specialized Wire Crossing Techniques
Treatment of coronary chronic total occlusions (CTOs) remains a challenging obstacle, posing a considerable barrier to achieving successful complete revascularization. By nature of their complexity, percutaneous CTO interventions are associated with lower rates of procedural success, higher complication rates, greater radiation exposure and longer procedure times compared with non-CTO intervent...
متن کاملCollagenase plaque digestion for facilitating guide wire crossing in chronic total occlusions.
BACKGROUND Chronic total occlusions (CTOs) are associated with significant angina, impaired left ventricular function, and worse long-term outcomes. Percutaneous coronary interventions in CTO are unsuccessful in up to 50% of cases, primarily because of inability to cross the lesion with a guide wire. Collagen is the predominant component of the atherosclerotic plaque. The objective of this stud...
متن کاملIntracoronary 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...
