TAVI: Boston Scientific’s Lotus valve tops Medtronic’s CoreValve – study
Data from a study of Boston Scientific‘s (NYSE:BSX) Lotus Valve showed a greater device success rate than Medtronic‘s (NYSE:MDT) CoreValve in high-risk transcatheter aortic valve replacement patients. The single-center, non-randomized study, published this month in the journal JACC: Cardiovascular Interventions, compared outcomes from 50 high-risk TAVI patients treated with the Lotus valve and 50 similar patients treated with Medtronic’s self-expanding CoreValve device. Success rates were higher at 30 days in the Lotus group, at 84%, versus 64% with CoreValve, according to the study.  These results...

Single-centre experience with next-generation devices for transapical aortic valve implantation ADULT CARDIAC
CONCLUSIONS In a real-world clinical setting, next-generation transapical THV yielded positive haemodynamic results. The incidence of relevant paravalvular regurgitation was scarce in this group and clinical outcomes were encouraging during short-term follow-up. Long-term follow-up is required to investigate the durability of these new devices.

Excellent Outcomes for Transcatheter Aortic Valve Replacement Within 1 Year of Opening a Low-Volume Centre and Consideration of Requirements
Conclusions Excellent outcomes can be achieved in newly initiated relatively low-volume centres, which compares favorably to previously published large series. Important considerations include appropriate team training, rigorous patient screening, use of multimodality imaging techniques, a heart team approach, constant integration of lessons learned from larger published experiences, and maintaining a recommended minimum volume of 25 cases per year.

Postoperative warfarin following mitral valve repair or bioprosthetic valve replacement.
CONCLUSION: The use of postoperative warfarin following MVR does not reduce the incidence of stroke at early follow up. However, there remains a trend for improved long-term outcomes in those patients receiving postoperative warfarin therapy. PMID: 24383387 [PubMed - indexed for MEDLINE]

Early clinical outcome of aortic transcatheter valve-in-valve implantation in the Nordic countries
Conclusions: Transcatheter valve-in-valve implantation is widely performed, albeit in small numbers, in most centers in the Nordic countries. The short-term results were excellent in this high-risk patient population, demonstrating a low incidence of device- or procedure-related complications. However, a considerable number of patients were left with suboptimal systolic valve performance with unknown long-term effects, warranting close surveillance after transcatheter valve-in-valve implantation.

Transcatheter Aortic Valve Implantation With the Edwards SAPIEN Versus the Medtronic CoreValve Revalving System Devices A Multicenter Collaborative Study: The PRAGMATIC Plus Initiative (Pooled-RotterdAm-Milano-Toulouse In Collaboration)
ObjectivesThe aim of this study was to compare outcomes after transfemoral transcatheter aortic valve implantation with the Medtronic CoreValve (MCV) versus the Edwards SAPIEN/SAPIEN XT transcatheter heart valve (ESV) for severe aortic stenosis.BackgroundNo large matched comparison study has been conducted so far evaluating both commercially available devices.MethodsThe data from databases of 4 experienced European centers were pooled and analyzed. Due to differences in baseline clinical characteristics, propensity score matching was performed. Study objectives were Valve Academic Research Consortium outcomes at 30 days an...
