OBJECTIVE: It is intuitive to suggest that knowledge of the variation in the anatomy of the aortic root may influence the outcomes of transcatheter implantation of the aortic valve (TAVI). We have now assessed such variation. METHODS: We used 26 specimens of normal hearts and 78 CT data sets of adults with a mean age of 64±15 years to measure the dimensions of the membranous septum and to assess any influence played by rotation of the aortic root, inferring the relationship to the atrioventricular conduction axis...

BACKGROUND: Acute Kidney Injury (AKI) is a frequent complication after a Transcatheter Aortic Valve Implantation (TAVI). Biomarkers such as urinary G1 cell cycle arrest proteins (TIMP-2 and IGFBP7) and sonographic evaluation (Doppler Renal Resistive Index (RRI)) have been advocated to predict AKI at an early stage after a TAVI-procedure. The primary aim was to determine the predictive value of these markers to detect AKI after a TAVI-procedure at an early phase. PATIENTS AND METHODS: In a prospective observational study, 62 consecutive patients were scheduled for a TAVI...

PURPOSE: To determine the time point at which thrombocytopenia after TAVI procedure is an indicator of the worst prognosis, with special consideration of perioperative platelet and coagulation activation as its potential causes. METHODS: Thirty two patients (mean age 78.5±7.9years, 62% females) qualified for TAVI procedure were prospectively evaluated. Platelet counts were assessed at baseline and for the next three postoperative (POD) days. Platelet activation was evaluated by P-selectin (PS, serum, ELISA) and platelet factor 4 (PF-4, CTAD plasma), and blood coagulation activation by prothrombin fragments 1+2 (F1+2, plasma, ELISA)...

BACKGROUND / PURPOSE: The Lotus valve (Boston Scientific, Natick, MA, USA) is a contemporary transcatheter aortic valve implantation (TAVI) device that is fully repositionable and retrievable to aid implantation and optimise procedural results. The ability to implant the device without routine pre-dilatation is another possible advantage reducing associated risks and procedure times. The aim of this study is to report procedural and 30-day outcomes following TAVI in a consecutive patient group presenting with severe symptomatic aortic stenosis with the Lotus valve system without routine pre-dilatation...

OBJECTIVES: To assess the feasibility of axillary transcatheter aortic valve implantation (TAVI) using the Lotus valve. BACKGROUND: TAVI is used to treat patients with severe aortic stenosis, with transfemoral (TF) access being the safest and most widely used route. In patients unsuitable for this, there are reports that the axillary artery may be safest alternative access route. The Lotus device is a fully retrievable 2nd generation transcatheter heart valve which is licensed for femoral and transaortic access...

The relationship between adherence to the recommended CoreValve sizing parameters and clinical outcomes is not well known for the recently released 34 mm valve, which is currently the largest available transcatheter valve. There is a presumed temporal reduction in paravalvular regurgitation in patients who receive an in-range valve, however, certain patients possess annular dimensions that are too large. We therefore describe two patients with annular dimensions larger than the manufacturer recommended range for the 34 mm CoreValve, who despite this underwent transcatheter aortic valve replacement with excellent clinical outcomes...

BACKGROUND: The valve-in-valve procedure, in which a transcatheter heart valve (THV) is implanted over a prosthetic valve, has been shown to be safe and therapeutically effective, depending on the size of the replacement valve.Methods and Results:We report 3 cases of successful valve-in-valve procedure to replace a degenerated 19-mm stented prosthetic aortic valve. Balloon-expanding THVs were implanted: 20-mm in the 1st case and 23-mm in the next 2. Aortic stenosis was almost completely resolved in all patients, who recovered promptly and without cardiac adverse events...
