Percutaneous coronary interventions (PCI) of coronary chronic total occlusions (CTO) increase the risk of high radiation exposure for both the patient and the cardiologist. This study evaluated the maximum dose to the patients' skin (MSD) and the exposure of the cardiologists during CTO-PCI. Moreover, the efficiency of radioprotective drapes to reduce cardiologist exposure was assessed. Patient dose was measured during 31 procedures; dose to the cardiologist's extremities were measured during 65 procedures, among which 31 were performed with radioprotective drapes...

This retrospective, single-center study assessed the prognostic value of several emerging inflammatory markers as predictors of in-stent restenosis (ISR) after drug-eluting stent implantation for coronary chronic total occlusion (CTO) lesions. Consecutive patients (n = 416) who underwent successful percutaneous coronary intervention (PCI) for documented CTO lesions and with follow-up angiography were enrolled. Preprocedural high-sensitivity C-reactive protein (hsCRP), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and red cell distribution width (RDW) were analyzed...

A 67-year-old man with coronary artery disease and previous coronary underwent successful Guideliner reverse CART percutaneous coronary intervention of a chronic total occlusion of the right coronary artery. He later developed evidence of myocardial ischemia, and imaging, including angiogram, echocardiogram, and cardiac computed tomography revealing active dye extravasation from the previously normal RV marginal branches, in addition to a large subepicardial hematoma. Despite these dramatic findings, the patient remained hemodynamically stable and pain-free, with resolving ECG changes...

OBJECTIVES: To evaluate the outcomes of subadventitial stenting (SS) around occluded stents for recanalizing in-stent chronic total occlusions (IS-CTOs). BACKGROUND: There is little evidence on the outcomes of SS for IS-CTO. METHODS: We examined the outcomes of SS for IS-CTO PCI at 14 centers between July 2011 and June 2017, and compared them to historical controls recanalized using within-stent stenting (WSS). Target-vessel failure (TVF) on follow-up was the endpoint of this study, and was defined as a composite of cardiac death, target-vessel myocardial infarction, and target-vessel revascularization...

Stress testing is endorsed by the American College of Cardiology/American Heart Association Appropriate Use Criteria to identify appropriate candidates for Chronic Total Occlusion (CTO) Percutaneous Coronary Intervention (PCI). However, the relation between stress test risk classification and health status after CTO PCI is not known. We studied 449 patients in the 12-center OPEN CTO registry who underwent stress testing before successful CTO PCI, comparing outcomes of patients with low-risk (LR) versus intermediate to high-risk (IHR) findings...

This study was performed to investigate lesion characteristics and procedural outcomes of re-attempted percutaneous coronary intervention (PCI) for chronic total occlusion (CTO). Prior failure of percutaneous revascularization of CTO has been identified as an independent predictor of failure at subsequent attempts. However, procedural outcomes of re-attempted PCI for CTO have not been elucidated. We evaluated lesion characteristics and procedural outcomes in 310 consecutive patients undergoing CTO-PCI, and compared the results between re-attempted (n = 59) and initial procedures (n = 251)...
