Results of aortic valvuloplasty in the era of TAVI

Results of aortic valvuloplasty in the era of TAVI

Original title: Balloon aortic valvuloplasty in the era of transcatheter aortic valve replacement: Acute and long-term outcomes. Reference: Hélène Eltchaninoff et al. Am Heart J 2014;167:235-40. Late 80s  initial enthusiasm in aortic valvuloplasty was quickly tempered with the publication of several studies showing a high rate of complications, poor durability and little or no impact on survival. Since

TAVI: emergency surgery is rare

Original title: Emergent cardiac surgery during transcatheter aortic valve implantation (TAVI): insight from Edwards SAPIENS Aortic Bioprótesis European Outcome (SOURCE) registry Reference: Holger Eggebrecht, et; al. Eurointervention 2013; 9online publish-ahead of print november 2013 Percutaneous aortic valve implantation has grown significantly since its inception, to be a safe procedure. The need for emergency cardiac surgery is rare, its

Looking for the best anti-aggregation scheme after TAVI

Original title: Comparison of Two Antiplatelet Therapy Strategies in Patients Undergoing Transcatheter Aortic Valve Implantation. Reference: Eric Durand et al. Am J Cardiol 2013, et al. Percutaneous aortic valve replacement has been shown to be superior to medical treatment in inoperable patients and not inferior to surgery in high-risk patients. Anti-platelet therapy in these patients is usually

The largest series of post TAVI coronary occlusion published

Original title: Predictive Factors, Management and Clinical Outcomes of Coronary obstruction Following Transcatheter Aortic Valve Implantation Insight From a Large Multicenter Registry Reference: Henrique B. Ribeiro, et; al. J Am Coll Cardiology 2013;62:1552-62 Percutaneous implantation of the aortic valve is a valid strategy in high-risk surgical patients. One of the possible complications of this procedure is the occlusion

Silent cerebral embolism during percutaneous valve implantation does not appear to cause cognitive impairment

Original title: Cognitive trajectory after transcatheter aortic valve implantation. Reference: Ghanem A et al. Circulation Cardiovasc Intervent. 2013;Epub ahead of print   Several studies showed that silent cerebral embolism in patients undergoing percutaneous aortic valve replacement is frequent but seems that does not affect the long-term cognitive functions according to this new study.  This study included 111 patients

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
