This study describes the accuracy of the new computed tomography (CT) technique to calculate fractional flow reserve (FFR). Other CT techniques to measure FFR use allometric scaling and assume coronary microvascular resistance. However, instead of assuming these parameters, this new technique calculates them based on coronary and aorta lumen deformation. The accuracy of this...
Courtesy of Dr. Carlos Fava. Around 5% of patients undergoing coronary angiography present severe left main coronary artery (LMCA) lesions. Myocardial revascularization surgery (MRS) is the preferred method for this group, although there is evidence from different randomized trials demonstrating the safety and efficacy of unprotected LMCA angioplasty, with results similar to those obtained through the traditional strategy....
Stent edge restenosis continues to be a weakness of drug eluting stents (DES). The aim of this study was to determine its predictors using optical coherence tomography (OCT). The study retrospectively analyzed 319 patients receiving OCT immediately after everolimus eluting stent implantation (EES) looking into the immediate outcome, and follow up angiography at 9...
Courtesy of Dr. Guillermo Migliaro. Coronary angiography and angioplasty via transradial approach are associated with a significant reduction in access site complications, compared with transfemoral and transbrachial access. Moreover, a significant reduction in mortality has been reported for procedures performed via transradial approach vs. transfemoral approach in primary angioplasty. There is a limited number...
The FUTURE study, testing the utility of functional revascularization by measuring the fractional flow reserve (FFR), was halted early by its safety committee due to an increased mortality rate at 1 year among patients guided by FFR. In this unexpected unprecedented outcome, 17 patients in the FFR-guided group died at a year of follow-up, compared with 7 patients...
Compared to men, women have less chances of developing obstructive coronary artery disease (CAD), but this new study suggests they are more prone to have lower coronary flow reserve, which is also a risk factor. Evidently, ischemic cardiomyopathy entails far more than assessing and treating plaque burden in epicardial arteries. In women, the most...
The symposium will take place on December 1, 2016, from 10:15 to 11:30, at “Osorno A” Room of Patagónico Hotel in Puerto Varas, in the context of SOLACI Sessions Chile 2016. This event on complex cardiomyopathy is organized by the Society for Cardiovascular Angiography and Interventions (SCAI) together with SOLACI. Moderators are Drs....
The aim of this study was to explore the relationship between temporal changes in coronary plaque volume and the intensity of lipid lowering treatments using coronary computed tomography (CTA). Coronary computed tomography has acceptable accuracy in terms of quantitative measurement on plaque volume, enough to identify changes in volume according to LDL levels. ...
This study presented at the ESC and simultaneously published in Circulation, is the first randomized controlled study to support the use of optical coherence tomography (OCT) in the context of ACS patients. The study randomized 240 patients undergoing non ST elevation acute coronary syndrome to OCT guided PCI (before and after PCI) vs. conventional...
This study looked at the role of fractional myocardial mass (vessel-specific myocardial mass) in the assessment of stenosis physiological severity. Researchers used CT angiography to study this new concept of myocardial mass subtended by a specific vessel, which could reduce anatomical-physiological mismatch. The study included 463 patients with 724 lesions evaluated by multislice...
