Patients were registered to receive a...
Original title: Transcatheter Aortic Valve Replacement in Bicuspid Aortic Valve Disease. Reference: Darren Mylotte, et al. J Am Coll Cardiol 2014;64:2330-9 The bicuspid aortic valve (BAV) is present between 0.5% and 2% of the general population and up to 20% of patients older than 80 years who require aortic valve surgery. Literature on transcatheter aortic valve...
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...

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...
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...
