Transcatheter valve replacement for bicuspid aortic valve stenosis

Original title: Comparison of Results of Transcatheter Aortic Valve Implantation in Patients with Severely Stenotic Bicuspid versus Tricuspid or Non-Bicuspid Valves. Reference: Charis Costopoulos et al. Am J Cardiol. 2014 Jan 31. pii: S0002-9149(14)00554-2.   The bicuspid aortic valve (BAV) is the most common congenital cardiac malformation. It occurs in approximately 1% of the general population and often...

Aortic regurgitation: the best predictor of post TAVI mortality

Original title: Post-procedural aortic regurgitation in balloon-expandable and self-expandable TAVR procedures: analysis of predictors and impact on long-term mortality: insights from the FRANCE 2 registry. Reference: Van Belle E et al. Circulation. 2014; Epub ahead of print.   This study used transthoracic echocardiography (TTE) to evaluate 2769 patients undergoing successful TAVI in 34 centers in France, enrolled in...

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...

The need for pacemaker post TAVI does not change the prognosis

Original title: Impact of Permanent Pacemaker Implantation on Clinical Outcome Among Patients Undergoing Transcatheter Aortic Valve Implantation. Reference: Lutz Buellesfeld et al. J Am Coll Cardiol 2012;60:493–501 Although pacemaker implantation after a percutaneous aortic valve (TAVI) implantation, constitutes a significant proportion of the complications related to the procedure, this is generally considered a benign event.  This study analyzed...

TAVI and cardiac tamponade, a rare but serious complication.

Original title: Incidence, Management and Outcomes of Cardiac Tamponade During Transcatheter Aortic Valve Implantation Reference: Ahmed Rezq et al. J Am Coll Cardiol Intv 2012;5:1264 –72 Transcatheter Aortic Valve Implantation (TAVI) for high risk patients is a valid strategy today but not without complications. Among these is cardiac tamponade, still rare but important because of its implication.  There...

Post TAVI LVEF Improvement: Only with No New Conduction Defects

Original title: Impact of a New Conduction Defect Alter Transcatheter Aortic Valve Implantation on Left Ventricular Function Reference: Rainer Hoffmann, et al. J Am Coll Cardiol Intv 2012;5:1257– 63. TAVI development in high risk patients can produce new conduction defects and require a definitive pacemaker in almost a third of treated patients.  The aim of this study was...

Transfemoral Transcatheter Aortic Valve Implantation: more experience and better results.

Original title: Trends in outcome after transfemoral transcatheter aortic valve implantation. Pooled-RotterdAm-Milano-Toulouse In Collaboration Plus (PRAGMATICPlus) initiative. Reference: Nicolas M. Van Mieghem et al. Am Heart J 2012;0:1-10. Article in press. Since its introduction in 2002, Transfemoral Transcatheter Aortic Valve Implantation (TAVI) has turned into a viable and safe strategy to treat patients with severe acute stenosis and...

Aortic insufficiency has a poor prognosis in TAVI.

Original title: Impact of Post-Procedural Aortic Regurgitation on Mortality Alter Trancatheter Aortic Valve Implantation Reference: Kentaro Hayashida, et al. J Am Coll Interv 2012;5:1247-56 Transcatheter aortic valve implantation (TAVI) sprung up as a valid strategy to treat patients with severe high risk AS (aortic stenosis). However, residual aortic regurgitation (post AR) and post-dilation remain unsolved.  Between October 2006...

The largest published series of valve-in-valve with Core Valve, (Medtronic).

Original title: Valve-in-Valve Implantation of Medtronic CoreValve Prosthesis in Patients with Failing Bioprosthetic Aortic Valves. Reference: Axel Linke el al. Circ Cardiovasc Interv. 2012;5:689-697. This study evaluates the safety, feasibility and results of Core Valve implants on patients with bioprostheses dysfunctional by stenosis, insufficiency or a combination of both. Biological prostheses are preferred over mechanical ones for patients...
