Spanish-Portuguese multicentre CIBELES study (Raul Moreno, Madrid, Spain) compared two drug-eluting stents – an everolimus (Xience V, Abbott Vascular, USA) and a sirolimus-releasing eluting stent (Cypher Select, Cordis Corporation, Miami Lakes, Florida, USA) in the context of total chronic coronary occlusions. With a non-inferiority design, the study randomized 208 patients (1:1), using as the primary...
Successful rechanneling of a chronic total occlusion (currently around 90%) leads to significant improvement in quality of life and symptom frequency in patients with stable chronic angina compared with optimal medical treatment alone. These results are promising and what we ultimately expected, although symptoms, as a primary endpoint in themselves, are in the eye of...
Courtesy of the SBHCI. Chronic total occlusions represent around 18% of all coronary lesions. However, they account for just 5% of all interventions, which means that many patients only receive medical treatment. This prospective, open, multicenter study randomized patients with multivessel lesions in whom at least one of these was a chronic total occlusion. Patients...
Courtesy of SBHCI. The PRISON IV trial compared the sirolimus eluting stent with ultra-thin struts and biodegradable polymer vs. the second-generation everolimus-eluting stent with thin struts and durable polymer in successfully recanalized chronic total occlusions. This is a sub-study with optical coherence tomography (OCT). The study included 330 patients, 85% angiographically followed up at...
Original Title: Successful Recanalization of Native Coronary Chronic Total Occlusion Is Not Associated With Improved Long-Term Survival. Reference: Pil Hyung Lee et al. J Am Coll Cardiol Intv. 2016. Online before print. The aim of this study was to assess long term clinical outcomes after successful recanalization of chronic total occlusion (CTO) with DES...
While the use of intravascular ultrasound (IVUS) during coronary intervention proved useful in multiple studies, there is limited evidence in the literature regarding its use in specifically in chronic total occlusions. The IVUS may help guide in recognizing the true lumen and better distal positioning, better coverage of stent, an optimal apposition and expansion, diagnose...

For years, treating dyslipidemia mainly focused on reducing LDL cholesterol (LDL-C) with statins, which had shown benefits in reducing atherosclerotic cardiovascular disease (ASCVD). Lipoprotein(a) [Lp(a)] is a form of apoB-containing lipoprotein bound to a hydrophilic, highly glycosylated protein called apolipoprotein(a) [apo(a)]. Circulating levels of Lp(a) are genetically determined, and are hardly affected by eating habits...
Patients with peripheral vascular disease often experience femoropopliteal compromise. It is estimated that approximately 50% of lesions in this area are chronic total occlusions (CTO). Even though success rate has improved for peripheral CTO treatments, long term clinical and technical outcomes have not been fully determined yet. Prior research has looked into stenting outcomes in...
A lesion ≥50% in the left main coronary artery (LMCA) is considered severe, according to various scientific societies, regardless of the presence of symptoms or ischemia, due to the extent of myocardium at risk. In such cases, revascularization is indicated. In many patients, lesions in this section of the coronary artery have severe calcification, which...
