Collateral circulation develops during the gradual progression of coronary occlusions in order to replace the original artery and supply blood to areas jeopardized by ischemia. However, the relevance of collaterals has remained controversial for many years. Several works have suggested a rapid regression of collaterals after rechanneling of chronic total coronary occlusions, which could render...
The association between glycemic control after coronary angioplasty and outcomes of the latter is controversial in many studies. We have come to think that the risk lies in suffering from diabetes, as if it was an unmodifiable factor. We have also come to believe that glycemic control can impact microvascular complications while it cannot do...
Little is known about how good are our counseling efforts on medication use and lifestyle as regards patients with peripheral vascular disease. More often than not, we use our time with these patients to discuss the technical feasibility of rechanneling, or to analyze the risk of eventual amputation. However, how often do we seize the...
Courtesy of Dr Carlos Fava. The association of primary angioplasty with multivessel lesions is not infrequent and has been analyzed in various studies and meta-analyses. However, the proper course of action remains unclear. According to this study, fractional flow reserve (FFR) could better define the ischemic impact of lesions and help with the identification of...
In the initial management of patients with stable chronic angina, a non-invasive strategy with cardiovascular MR perfusion imaging seems to provide similar results to invasive strategies. At one year, MACE rate (combination of all cause death, non-fatal infarction and target vessel revascularization) resulted 3.3% for MRI vs. 3.9% for fractional flow reserve (FFR) informed...
Two recent articles featured in JACC Cardiovascular Interventions showed that short term (at 30 days) outcomes of patients treated with the next-generation self-expanding Medtronic Evolut R valves could present several advantages compared to the original CoreValve, including recapturability. Both analyses reported similar rates of all-cause mortality and stroke. The study carried out by Dr. Jeffrey Popma as...
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...
We thank all the speakers of the Bolivia Sessions2017 who shared their presentations to contribute to our mission of promoting Interventional Cardiology in Latin America. See them below Agatiello, Carla: “Como iniciar un programa TAVI en Latinoamérica”. Arregui, Elizabeth: “Estenosis aórtica: candidatos para TAVI”. Bello, Fernando: “Enfermedad carotídea: Tratamiento quirúrgico”. ...
The goal of this study was to assess all available revascularization strategies for patients undergoing ST elevation acute myocardial infarction and multivessel disease. Among the strategies to treat this group of patients, there were: culprit vessel intervention only, culprit vessel intervention and, in case of success, multivessel intervention, culprit vessel intervention with staged revascularization,...
There is little information on the short and mid-term evolution of cognitive function after transcatheter aortic valve replacement (TAVR). The aim of this study was to describe global changes in cognitive function and changes in specific cognitive domains one year after TAVR. Fifty one patients undergoing TAVR, median age 80, were prospectively followed...
