The EXCEL study, originally presented at TCT 2016 and published simultaneously in the New England Journal of Medicine (NEJM), showed that angioplasty and surgery in patients with left main coronary artery disease have similar rates of mortality, infarction, and stroke at 3 years. This sub-study, recently published in J Am Coll Cardiol Intv, adds that the...
The EXCEL trial did not find the sex of patients with left main coronary artery disease to be an independent predictor of adverse events after revascularization. However, women who underwent angioplasty had a trend towards worse outcomes, a finding that might be related to comorbidities and somewhat increased chances of peri-procedural complications. In its formal...
Endovascular therapy is now considered as the standard of care for acute ischemic stroke caused by large vessel occlusion. The time between symptoms onset and reperfusion emerges as the most determinant factor for good clinical outcomes, much more strongly than even in acute myocardial infarction. The saying “time is brain” is even more relevant than...
Courtesy of Dr. Alejandro Lakowsky, MTSAC (Full Member of the Argentine Society of Cardiology) The New England Journal of Medicine (NEJM) recently published an article about the POINT trial (simultaneously presented at the European Stroke Organisation Conference), a long-awaited randomized clinical trial to assess the efficacy and safety of dual antiplatelet therapy (DAPT) with aspirin...
This meta-analysis included 14 studies and compared the uptake of fluorodeoxyglucose (18F-FDG) according to positron emission tomography (PET)/computed tomography (CT) in symptomatic versus asymptomatic patients, demonstrating a significantly higher uptake in patients with symptomatic lesions. While PET/CT imaging of atheroma is a tool under investigation, with limited applicability in clinical practice, in a relatively close future,...
The rate of cerebrovascular events in TAVR hovers about 4% in most of the current studies, regardless the center, the operator or the prosthetic valve. At present, no scores can adequately predict which patients run the highest risk of stroke during TAVR, and the routine use of cerebral protection devices remains controversial. The SENTINEL study...
Cryptogenic stroke patients with migraine have high prevalence (79%) of patent foramen ovale (PFO) with right to left shunt. However, the timing of stroke in migraineurs is not usually associated to a migraine attack. These observations are consistent with the hypothesis that the most likely mechanism of stroke in these patients with migraine is a...
The association between aortic stenosis and some degree of mitral stenosis (MS) is around 10% (depending on the series), and it is related with negative outcomes. In high-risk and inoperable patients who underwent TAVR, that association and its significance have not been studied yet. The study analyzed data from the Society of Thoracic Surgeons/American...
Aortic stenosis increases afterload creating hypertrophy as a compensation mechanism to maintain minute volume. This leads to left ventricular diastolic dysfunction (LVDD). More than half of patients presenting aortic stenosis have LVDD and myocardial fibrosis, which is a mortality predictor in surgery. At present, there is contradicting evidence in TAVR. The study looked...
The prevalence of peripheral arterial disease is between 15% and 20% of patients older than 65 years and its severity is greatly underestimated. In fact, annual mortality is higher in patients with peripheral arterial disease (8.2%) than in those after acute myocardial infarction (6.3%). Despite the above, medical advice and efforts to modify risk factors...
