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

Patent Foramen Ovale: when to indicate closure

References: Matthew Nayor et al. Contemporary Approach to Paradoxical Embolism. Circulation. 2014;129:1892-1897. Marco Hernandez-Enrıquez et al.  Current Indications for Percutaneous Closure of Patent Foramen Ovale.  Rev Esp Cardiol. 2014;67(8):603–607. The debate on patent foramen ovale behavior in different clinical contexts remains open, no pun intended. Based on numerous observational studies and expert recommendations, when facing the

Worse post TAVI ejection fraction recovery in coronary artery disease patients without revascularization

Original title: Impact of coronary artery disease on left ventricular ejection fraction recovery following transcatheter aortic valve implantation. Reference: Freixa X et al. 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

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
