MITRAL: First cases of Transcatheter Mitral Valve Implantation (TMVI)

Severe mitral regurgitation is three times more prevalent than aortic stenosis in the elderly population at high risk and poor prognosis if not treated. Fortis mitral valve was designed using several preclinical models and are now tested for the first time in 4 patients resulting in various technical difficulties and finally the death of 3...

JUPITER: transapical TAVI device

We evaluated 88 consecutive patients (at this phase) with severe aortic stenosis who received the second-generation device for transapical access. Survival at thirty days was 85.1% with a cardiovascular death rate of 4.8%. No strokes were observed during this period. Average gradient reduction was highly significant, (40.4 to 8.1 mmHg, p <0.001), as well as...

DISCOVER: new low profile valve with little post-implant regurgitation

The objective of the study was to assess events after 30 days with the DirectFLOW Medical Valve device in patients with severe aortic stenosis and high surgical risk. The device is designed to reduce post-implant aortic regurgitation; it has a low profile and high navigability and requires no post-dilatation or rapid pacing. The study included...

Frequency, indication and evolution of emergency cardiac surgery during TAVI

Original Title: Emergent cardiac surgery during transcatheter aortic valve implantation (TAVI): insight the Edwards SAPIENS Aortic Bioprosthesis Outcome (SOURCE) registry. Reference: Holger Eggerbrecht, et al. EuroIntervention 2014;10:975-81 SOURCE register data from patients receiving transcatheter aortic valve implantation with the Edwards Sapiens valve, were analyzed; out of 2307 patients, 27 (1.2%) required emergency cardiac surgery (ECS). Valve stenosis was...

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...

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...

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, more risky in patients with peripheral vascular disease

Reference: Sinning et al. AHJ Am Heart J 2012;164:102-110 Percutaneous aortic valve replacement (TAVI) is a novel technique for the treatment of severe aortic stenosis (SAS) that has been built with great enthusiasm in clinical practice, particularly in patients with excessive surgical risk. In these patients, a high obstructive peripheral vascular disease stands, a fact...
