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…
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…
Transfemoral TAVI under local anesthesia with similar results to general anesthesia
Original title: Clinical outcomes and safety of transfemoral aortic valve implantation under general versus local anesthesia: subanalysis of the French Aortic National CoreValve and Edwards 2 registry. Reference: Oguri A et al. CircCardiovascInterv. 2014; 7:602-610. Transcatheter aortic valve replacement (TAVI) performed under local anesthesia is becoming an increasingly common procedure.

TAVI, also a promising option for severe aortic regurgitation
Original title: Initial German Experience With Tranapical Implantation of a Second-Generation Trascatheter heart Valve for the Treatment of Aortic Regurgitation. Reference: Moritz Seiffert, et al. JACC Cardiovasc Interv. 2014 Oct;7(10):1168-74. There is a group of patients with severe aortic regurgitation and they are not candidates for surgery; percutaneous implant is an option, but until now, there is little…

Catheter Cardiovasc Interv. 2014;Epub ahead of print. This single center study analyzed data form 56 consecutive patients with severe aortic stenosis and LVEF of ≤ 50% undergoing TAVI (transcatheter aortic valve implantation) between March 2006…
Mitra-Clip: a valid alternative for high risk patients
Original title: Percutaneous Mitral Valve Repair for Mitral Regurgitation in High-Risk Patients. Results of the EVEREST II Study. Reference: Donald D. Glower et al. J Am Coll Cardiol 2014;64:172-81 Severe mitral regurgitation (MR) often lead to hospitalization for cardiac failure and heart surgery. Half of these patients are rejected for high surgical risk. Percutaneous intervention is a valid…
Similar mortality outcomes with MitraClip and surgery in high risk patients with severe mitral valve regurgitation
Original title: Survival of transcatheter mitral valve repair compared with surgical and conservative treatment in high-surgical-risk patients. Reference: Swaans MJ et al. J Am CollCardiolIntv. 2014;7:875-881. In high-surgical-risk patients with symptomatic severe mitral valve regurgitation, MitraClip for transcatheter mitral valve repair and surgery showed similar survival rates in addition to superiority when compared to standard medical treatment. This…

Outcomes and CostAnalysis. Reference: VasilisBabaliaros et al. J Am CollCardiolIntv 2014;7:898–904. This retrospective study of a center analyzed the results of percutaneous aortic valve replacement (TAVR) performed with a minimally invasive technique that included the closure of the femoral access…
TAVR: Regression of Left Ventricular Hypertrophy Decreases Re-hospitalization
Original title: Early Regression of Severe Left Ventricular Hypertrophy After Transcatheter Aortic Valve Replacement Is Associated with Decreased Hospitalization. Reference: Brian Lindman, et al. JACC Cardiovasc Interv 2014;7:662-73. Left ventricular hypertrophy, defined by the increase of left ventricular mass, has long been associated to increased morbi-mortality in the context of different heart conditions. LV hypertrophy regression might…
