Abstract Background The interventional treatment of chronic total occlusion (CTO) with stent fracture as well as severe calcification was extremely difficult and no effective technique has been reported. Case presentation A 50-year-old woman was hospitalized for angina, angiography revealed triple vessel disease, CTO accompanied with stent fracture in right coronary artery (RCA). Treatment using conventional coronary intervention was expected to be difficult. Therefore, we performed RASER technique, which was a combination of excimer laser coronary atherectomy (ELCA) with rotational atherectomy (RA), followed by the deployment of drug-eluting stents. Intravascular ultrasound (IVUS) revealed well attachment of the stents, the patient was discharged 3 days after the procedure and no recurrent chest discomfort was reported in a follow-up time of 10 months. Conclusion This case report provided a first report of RASER technique in the treatment of CTO with stent fracture and severe calcification.

Abstract Background As an initial treatment strategy, percutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO) did not show mid-term survival benefits compared with optimal medical therapy (OMT). Purpose To compare 10-year clinical outcomes between OMT and PCI in CTO patients. Methods Between March 2003 and February 2012, 2,024 patients with CTO were enrolled in a single center registry and followed for about 10 years. We excluded CTO patients who underwent coronary artery bypass grafting, and classified patients into the OMT group (n=664) or PCI group (n=883) according to initial treatment strategy. Propensity-score matching was performed to minimize potential selection bias. The primary outcome was cardiac death. Results In the PCI group, 699 patients (79.2%) underwent successful revascularization. Clinical and angiographic characteristics revealed more comorbidities and more complex lesions in the OMT group than in the PCI group. At 10 years, the PCI group had lower risks of cardiac death (10.4% versus 22.3%; HR 0.43; 95% CI 0.32 to 0.57; p<0.001) than the OMT group. After the propensity-score matching analyses, the PCI group had lower risks of cardiac death (13.6% versus 20.8%; HR 0.62; 95% CI 0.44 to 0.88; p=0.007), acute myocardial infarction (6.3% versus 11.2%; HR 0.55; 95% CI 0.34 to 0.91; p=0.02), any revascularization (23.9% versus 32.2%; HR 0.67; 95% CI 0.51 to 0.88; p=0.004) than the OMT group. The beneficial effects of CTO PCI were consistent across various subgroups (all p-values for interaction: non-significant). Conclusions As an initial treatment strategy, PCI reduced late cardiac death compared with OMT in CTO patients.

AbstractChronic total occlusion (CTO) is a common challenge accounting for 10% of coronary lesions found on coronary angiography. Patients are frequently referred for bypass surgery because percutaneous coronary intervention is challenging in this subset. Recent advances in the hardware as well as the technical expertise and an algorithm approach have improved the success to more than 90%.Antegrade approach is the cornerstone for managing CTO and has two distinct strategies: antegrade wire escalation, and antegrade dissection and reentry strategy. Step-wise approach to perform these procedures and the use of adjunct imaging are discussed.
