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...

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...

Post TAVI Hypertension is a predictor of better evolution

Original title: Post-Procedural Hypertension Following Transcatheter Aortic Valve Implantation Incidence and Clinical Significance. Reference: Gidon Y. Perlman et al. J Am Coll Cardiol Intv 2013. Article in press. Pre-procedural hypertension (HTN) is a risk factor and a predictor of increased mortality after surgical aortic valve replacement (AVR). The disappearance of the pressure gradient across the aortic valve following...

Coronary Obstruction after TAVI: dreaded, but rare and solvable

Original title: Coronary Obstruction After Transcatheter Aortic Valve Implantation. A Systematic Review. Reference: Henrique Barbosa Ribeiro et al. J Am Coll Cardiol Intv 2013. Article in press. In the context of Transcatheter Aortic Valve Implantation (TAVI) there can be complications such as conduction disturbances, bleeding, residual aortic insufficiency or vascular complications, all of which have been detailed with...

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 also for pure aortic insufficiency

Original title: Transcatheter Aortic Valve Implantation for Pure Severe Native Aortic Valve Regurgitation. Reference: David A. Roy et al. J Am Coll Cardiol 2013. Article in press. Percutaneous aortic valve replacement (TAVI) has become a standard treatment for patients with severe aortic stenosis and a high surgical risk. However for those patients who have pure aortic insufficiency, (failure...

Favorable outcomes at 5 years post TAVI.

Original title: 5-Year Outcome After Aortic Valve Implantation Reference: Stefan Toggweiler, et al. J Am Coll Cardiol 2013;61:413–9 Percutaneous aortic valve implantation (TAVI) is now a valid strategy as we know its short and medium term evolution but we do not have enough information available about the long term.  The aim of this study was to analyze the...

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...
