We thank all the speakers of the Chile 2016 Sessions who shared their presentations to contribute to our mission of promoting the dissemination of information from research and clinical practice in Interventional Cardiology. You can read and/or download them below Lluberas, Ricardo. “Role of pharmacovasive therapy in the treatment of IAMcEST. Implications for Latin...
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...
Much of the speculation around the way of individualizing dual antiplatelet therapy (DAPT) duration after coronary angioplasty has focused on clinical parameters (e. g., diabetes), but a new study published by the Journal of the American College of Cardiology (JACC) and presented at the last European Society of Cardiology (ESC) Congress warns about anatomical factors as...
Myocardial blush is a predictor of mortality after primary angioplasty. Small studies showed a degree of improvement blush with manual thromboaspiration. The present work is a substudy of the TOTAL where thromboaspiration Export® catheter (Medtronic cardiovascular, Santa Rosa, CA) was assessed and compared to angioplasty without thromboaspiration. A total of 1610 patients were included, (791...
A bioabsorbable platform implant in the context of ST segment elevation acute myocardial infarction is feasible although the subsequent cicatrization of the artery is not documented. The objective of this work was to evaluate optical coherence tomography (OCT) in patients who received everolimus-releasing bioabsorbable platform in the context of primary angioplasty. A total of 39...
Infarct size is an independent predictor of survival and ventricular function. Several alternatives have been tried to reduce the size of the infarcted area and its consequences. Small pilot studies suggest that inhaled nitric oxide may improve reperfusion in acute myocardial infarction with ST-segment elevation. Patients were randomized to conventional treatment versus inhalation of 80...
Statins may help stabilize the atherosclerotic plaque in acute myocardial infarction. 103 patients who underwent primary angioplasty followed by coronary intravascular ultrasound (IVUS) in the culprit artery and not culprit of infarction were included. Patients received 20 mg of rosuvastatin for two weeks and then 40 mg for 13 months ending up with a new...
Current guidelines suggest treating only the culprit artery of myocardial infarction with ST-segment elevation. This prospective and randomized work included 296 patients in 7 centers suffering ST-segment elevation acute myocardial infarction referred for primary angioplasty randomized to treat only the culprit artery (n = 146) versus complete revascularization (n = 150). In the culprit artery...
Fundamentals: Previous studies have shown the benefits of a transradial approach in the context of coronary syndromes with ST-segment elevation. The aim of this study was to evaluate these benefits in AMI patients with ST-segment elevation within a window of up to 12 hours from the onset of symptoms. Methods: A randomized study conducted in...
Background: Contrast-induced nephropathy has been the subject of many studies not only because of the morbidity associated with prolonged hospital stay, (with dialysis requirement in some cases), but also with an increase in mortality in these patients. The preventive strategy hydration with saline solution 0.9% NaCl is the choice. However, the infusion rate and total...
