CLI-randomized study CLI-OPCI (n = 670, 1:1) evaluated the impact of stent implantation guided by angiography and optical coherence tomography (OCT), versus angioplasty guided alone by angiography. All patients who had been subjected to stent placement were then evaluated by angiography. Arm OCT, after an optimal angiographic result, an intracoronary OCT evaluation was performed. In...

Original title: Effectiveness of Fluorography Versus Cineangiography at Reducing Radiation Exposure During Diagnostic Coronary Angiography. Reference: Shah B et al. Am J Cardiol. 2014 Apr 1;113(7):1093-8. Coronary angiography is the gold standard for defining obstructive coronary disease. However, radiation exposure remains an unclear and unwanted risk. The aim of this study was to determine whether the new digital...
Original title: Intravascular Ultrasound-Guided Implantation of Drug-Eluting Stents to Improve Outcome. A Meta-Analysis. Reference: Jae-Sik Jang et al. J Am Coll Cardiol Intv 2014, epub ahead of print. Several previous studies and meta-analysis showed that implantation of conventional stents (BMS) intravascular ultrasound (IVUS) guided may decrease restenosis and clinical events. This information was not yet clear to drug-eluting...
Original title: Same-Day Discharge Compared With Overnight Hospitalization After Uncomplicated Percutaneous Coronary Intervention. A Systematic Review and Meta-Analysis Reference: Eltigani Abdelaal et al. J Am Coll Cardiol Intv 2013. Article in press. Coronary angioplasty and subsequent same day discharge in selected patients can reduce costs and increase patient comfort. Several observational studies and a few randomized studies have...
Percutaneous coronary intervention (PCI) with drug eluting stents (DES) can present limitations, especially in the form of stent thrombosis or instent restenosis (ISR). These findings have furthered the development of drub coated balloons (DCB). The safety and efficacy of DCB have already been shown in the context of ISR and de novo small vessel coronary...
While transcatheter aortic valve replacement (TAVR) has shown benefits, significant coronary artery disease affects 50% or more of patients who undergo such procedure. However, it is still unclear which is the best treatment strategy or how to handle this condition. Quantitative flow ratio (QFR) could be a non-invasive option to assess the severity of coronary...
At present, most percutaneous coronary intervention procedures (PCI) are done with drug eluting stents (DES). However, drug coated balloons (DCB) have shown benefits in restenosis and small vessel de novo lesions. Intravascular ultrasound (IVUS) has been shown effective in left main PCI and complex procedures, even though there is little infomration on its use for...
Coronary calcifications pose a complex challenge with a high incidence (25% of all angioplasties), thus implying difficult management and adverse long-term outcomes, such as an increased risk of events, especially the need for repeat revascularization. The main mechanisms of long-term failure include stent underexpansion and, in particular, minimal post-deployment stent area. Intravascular lithotripsy (IVL) has...
Nowadays, evidence from studies and meta-analyses has demonstrated the benefits of complete revascularization compared to culprit-vessel-only revascularization in patients with acute myocardial infarction (AMI). The identification and treatment of non-culprit lesions can be guided by conventional angiography, intracoronary imaging, or coronary physiology; the optimal modality, however, is still unclear. Quantitative flow ratio (QFR) is a...
