Mechanical versus bioprosthetic valves in chronic dialysis: a systematic review and meta-analysis
CONCLUSION: Mechanical valves were associated with reduced mortality, but increased rate of bleeding and stroke. Given very low certainty for evidence of mortality and stroke outcomes, patients and clinicians may choose prosthetic valves based on factors such as bleeding risk and valve longevity.STUDY REGISTRATION: PROSPERO no.

Sex-Specific Differences in Outcome of Transcatheter or Surgical Aortic Valve Replacement
ConclusionsThis nation-wide analysis of sex-specific outcomes after aortic-valve replacement procedures showed that women are higher-risk for bleeding, but lower-risk for stroke, mechanical ventilation, and TF-TAVR mortality. Understanding these differences and their basis may help improve outcomes.RésuméContexteLes différences anatomiques et celles au niveau des caractéristiques initiales entre patients de sexe masculin et féminin présentant une sténose valvulaire aortique pourraient influencer l’issue après un remplacement valvulaire aortique par voie chirurgicale et transcathéter. Nous avons évalué l’effe...

Transcatheter Aortic Valve Implantation Versus Re-do Surgery for Failing Surgical Aortic Bioprosthesis: a Multi-Centre Propensity Score Analysis.
CONCLUSIONS: Patients with aortic bioprosthesis failure treated with either redo-SAVR or TAV-in-SAV have similar 30-day and 1-year clinical outcomes. PMID: 28760721 [PubMed - as supplied by publisher]

Transcatheter vs Surgical Aortic Valve Replacement for Aortic Stenosis in Low-Intermediate Risk Patients: A Meta-analysis
Conclusions Although there was no difference in 30-day and late mortality, the rate of complications differed between TAVR and SAVR in the low-intermediate surgical risk population.

Neovasc touts Tiara TMVR success rate in study
A small study of the Neovasc (NSDQ:NVCN) Tiara transcatheter mitral valve replacement (TMVR) in high-risk patients revealed a 100% procedural success rate and immediate elimination of mitral regurgitation. Published in Circulation: Cardiovascular Interventions, the study also showed no death, myocardial infarction, stroke, major bleeding, or access site complications at 30 days. The twelve patients in the study had had a previous aortic valve replacement. Such patients have been excluded from most TMVR trials because of the potential risks of left ventricular outflow tract obstruction or interaction between the TMVR anch...

Impact of Discharge Location After Transcatheter Aortic Valve Replacement On 1-Year Outcomes In Women: Results From The WIN-TAVI Registry
ConclusionsIn women undergoing contemporary TAVR, discharge disposition significantly affects 1-year risk of outcomes even after adjustment for recorded baseline differences. This might suggest the necessity of considering additional factors beyond comorbidities in the TAVR decision-making process.
