Rationale and Technique for Percutaneous Coronary Intervention of Chronic Total Occlusions

摘要: Chronic total occlusions (CTOs) represent the “last frontier” of percutaneous coronary interventions (PCI). CTOs are frequently (~30 %) detected on diagnostic angiograms, but CTO PCI is currently performed infrequently mainly because higher technical difficulty and perceived risk complications. Nonetheless, successful can significantly improve patient’s quality life, left ventricular function, reduce need for subsequent artery bypass graft surgery, possibly long-term survival. The introduction novel catheters, guidewires, adjunctive imaging, techniques, operator volumes has led to an increased success rate PCI. Moreover, drug-eluting stents rates sustained patency following recanalization. This chapter aims provide overview anatomy histopathology CTOs, a concise review techniques devices PCI, comprehensive summary evidence regarding clinical relevance rationale
