Flow-Gradient Patterns can help in the selection of patients with aortic stenosis

Flow-Gradient Patterns can help in the selection of patients with aortic stenosis

Original title: Flow-Gradient Patterns in Severe Aortic Stenosis UIT Preserved Ejection Fraction. Clinical Characteristic and Predictos of Survival. Reference: Eleid, M, et al. Circulation 2013;128:1781-1789 Severe aortic stenosis is usually defined by echocardiography as a 40 mm mean transvalvular gradient Hg at >4 m/s; but there are low flow or paradoxical low flow cases with different evolution. 1704

Automatic measurement of the aortic annulus by TAC , more precisely to choose the correct valve size.

Original title: Automated 3-Dimensional Aortic Annular Assessment by Multidetector Computed Tomography in Transcatheter Aortic Valve Implantation. Reference: Yusuke Watanabe et al. J Am Coll Cardiol Intv 2013;6:955–64. Percutaneous aortic valve implantation ( TAVI ) has emerged as an alternative for patients with severe aortic stenosis and high surgical risk. While this technique was improved over the time, residual paravalvular regurgitation

Low flow impact on outcomes following TAVI should be taken into account

Original title: Impact of Low Flow on the Outcome of High-Risk Patients Undergoing Transcatheter Aortic Valve Replacement. Reference: Florent Le Ven, et al. J Am Coll Cardiol 62;9:792-788 A study of low flow (SVi <35ml/m2) in the context of severe aortic stenosis has shown it is a predictor of worse outcomes after surgery, even though evolution with medical

Implanting a second valve and embolization are two complications that increase mortality

Original title: Determinats and Outcomes of Acute transcatheter Valve-in Valve Therapy or Embolization. Reference: Raj R Makkar, et al. J Am Coll Cardiol 2013;62:418-30   Percutaneous aortic valve implantation has proven to be feasible, safe and a successful follow up. Only in a few patients is the two-valve implantation necessary due to bad positioning or embolism but

Percutaneous mitral valve treatment is a valid alternative in the long term

Original title: 4-Year Results of a Randomized Controlled Trial of Percutaneous Repair Versus surgery for Mitral Regurgitation. Reference: Laura Mauri, et al. J Am Coll Cardiol 2013;62:317-28 Surgical treatment of mitral regurgitation (MR) is currently recommended by either valve replacement or valvuloplasty. Devices are being developed to address this disease giving the benefits of percutaneous treatments. The EVEREST

Percutaneous Left Atrial Appendage Suture: more options in atrial fibrillation patients with antiguagulation contraindication

Original title: Percutaneous Left Atrial Appendage Suture Ligation Using the Lariat Device In Patines UIT Atrial Fibrillation Reference: Krystof Bartus, et al. J Am Coll Cardiol 2013;62:108–18. Atrial fibrillation (AF) is the most frequent arrhythmia and is associated with a 5 fold increase in stroke risk and the resulting morbimortality. Warfarin anticoagulation therapy can be effective but only

Percutaneous Left Atrial Appendage Closure With the AMPLATZER : a valid alternative when anticoagulation is contraindicated

Original title: Percutaneous Left Atrial Appendage Closure With the AMPLATZER Cardiac Plug Device in Patients With Nonvalvular Atrial Fibrillation and Contraindication to Anticoagulation Therapy Reference: Marina Urena, et al. J Am Coll Cardiol 2013:62:96-102.   Anticoagulation is a good therapeutic strategy in nonvascular atrial fibrillation (AF). However, it is contraindicated in approximately 10% of patients, due to the

Thoracoscopic Stand-Alone Left Atrial Appendectomy

Original title: Thoracoscopic Stand-Alone Left Atrial Appendectomy for Thromboembolism Prevention in Nonvalvular Atrial Fibrilation. Reference: Toshiya Ohtsuka, et al. J Am Coll Cardiol 201362;2:103-107 Anticoagulation is commonly prescribed as prevention therapy against AF-induced thromboembolism. However, even a correct prescription may result in an unexpected stroke due to cardioembolic stroke. Different left atrial appendectomy techniques and devices are currently

What is the contrast media dosing that predicts acute kidney injury after TAVI?

Original title: Renal Function-Based Contrast Dosing Predicts Acute Kidney Following Trancatheter Aortic Valve Implantation Reference: Masanori Yamamoto, et al. J Am Coll Cardiol Intv 2013;6:479–86. Acute kidney injury (AKI) presents in 10 to 30% of patients undergoing TAVI; it is associated to the increase of morbidity and mortality and it prolongues hospitalization. This study included 415 patients with

QRS after TAVI, The Best Predictor for safe transitory pacemaker removal

Original title: Patients Without Prolonged QRS After TAVI with CoreValve Device do not Experience High-Degree Atrio-Ventricular Block. Reference: Gauthier Mouillet et al. Catheterization and Cardiovascular Interventions 81:882–887 (2013). High degree atrioventricular block (AVB) in the context of transcatheter aortic valve implantation (TAVI) has been reported with variable incidence (3-45%) depending on the population characteristics and the kind of

Prosthetic endocarditis after TAVI, rare and difficult to diagnose

Original title: Prosthetic valve endocarditis after transcatheter aortic valve implantation: the incidence in a single-centre cohort and reflections on clinical, echocardiographic and prognostic features. Reference: Miriam Puls et al. EuroIntervention 2013;8:1407-1418. Prosthetic valve endocarditis is a serious complication of surgical valve replacement and occurs in 0.3 to 1.2% of patients per year. It is basically divided in early
