Risks and benefits of Dual Antiplatelet beyond the year of a drug-eluting stent
Original title: Twelve or 30 Months of Dual Antiplatelet Therapy after Drug-Eluting Stents. Reference: Laura Mauri et al. N Engl J Med 2014;371:2155-66. Dual antiplatelet therapy is recommended after a drug-eluting stent to prevent thrombotic complications. The clinical benefit of this scheme it is not clear beyond one year. Patients were registered to receive a…

Third generation percutaneous aortic valve in intermediate-risk patients
Original title: Multicenter Evaluation of a Next-Generation Balloon-Expandable Transcatheter Aortic Valve. Reference: John Webb, et al. J Am Coll Cardiol 2014;64:2235-43 Percutaneous aortic valve replacement is starting to be a reasonable alternative in patients at intermediate risk. One hundred and fifty patients who received SAPIEN 3rd generation percutaneous aortic valve implantation were analyzed prospectively. The STS score of…

Stress echocardiography in low flow, low gradient aortic stenosis with deteriorated systolic function
Echocardiography Favaloro Foundation. Buenos Aires, Argentina. JACC Cardiovascular Imaging has recently published a retrospective analysis including severe aortic stenosis patients (< 1 cm²), with low gradient (mean aortic gradient Patients that had undergone dobutamine stress echocardiography (DSE) to distinguish pseudo aortic stenosis (n=49) were selected. These results were used to determine flow reserve (FR). The…
Hybrid Revascularization in Multiple Vessels
Original title: Hybrid Revascularization for Multivessel Coronary Artery Disease Reference: Mariuz Gassior, et al. J Am Cardiol Intv 2014;7:1277-83 According to the international guidelines, coronary artery bypass grafting (CABG) continues to be the “Gold Standard” treatment for multiple vessels diseases. However, second generation DES and the hybrid strategy may eventually change indications. This study randomized 102…
