Results of the new repositionable and retrievable percutaneous valve system

Original title: Transcatheter Aortic Valve Replacement for Severe Symptomatic Aortic Stenosis Using a Repositionable Valve System. 30-Day Primary Endpoint Results From the REPRISE II Study. Reference: Ian T. Meredith AM et al. J Am Coll Cardiol 2014;64:1339–48. Transcatheter aortic valve replacement (TAVR) showed results comparable to those of surgery in patients at high surgical risk, but complications can

Percutaneous treatment of aortic coarctation with self-expandable uncovered nitinol stent

Original title: Percutaneous treatment of adult isthmic aortic coarctation: acute and long-term clinical and imaging outcome with a self-expandable uncovered nitinol stent. Reference: Kische S et al. Circ Cardiovasc Interv. 2015 Jan;8(1).   The aim of this study was to show perioperative and long term results of the percutaneous treatment of aortic coarctation with the self-expandable uncovered nitinol

Frequency, indication and evolution of emergency cardiac surgery during TAVI

Original Title: Emergent cardiac surgery during transcatheter aortic valve implantation (TAVI): insight the Edwards SAPIENS Aortic Bioprosthesis Outcome (SOURCE) registry. Reference: Holger Eggerbrecht, et al. EuroIntervention 2014;10:975-81 SOURCE register data from patients receiving transcatheter aortic valve implantation with the Edwards Sapiens valve, were analyzed; out of 2307 patients, 27 (1.2%) required emergency cardiac surgery (ECS). Valve stenosis was

Promising results of TAVR in Bicuspid Aortic

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

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

Long-term septal ablation in hypertrophic cardiomyopathy

Original title: Periprocedural Complication and Long-Term Outcome After Alcohol Septal ablation in hypertrofic Obstructive cardiomyopathy. A Single-Center Experience. Reference: Robbert Steggerda, et al. J Am Coll Cardiol Intv 2014;7:1227-34. Septal ablation is an alternative to surgery in hypertrophic cardiomyopathy (HCM), but indications and evolution are not fully established.161 patients who received septal ablation (SA) and 102 who received

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. This study compared clinical outcomes in patients

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
