Short- and long-term outcomes in dialysis patients undergoing transcatheter aortic valve implantation: a systematic review and meta-analysis
ConclusionDialysis patients had significantly higher rates of short- and long-term mortality, short-term life threatening and/or major bleeding, permanent pacemaker implantation, and device failure compared to non-dialysis patients. Careful patient selection who would benefit from TAVI in patients with ESRD requiring dialysis, is necessary to prevent high-rates of post-procedural complications.

Flow, Reflected by Stroke Volume Index, Is a Risk Marker in High-Gradient Aortic Stenosis Patients Undergoing Transcatheter Aortic Valve Replacement
ConclusionsSVi can further characterize patients with HG-AS and may help to identify those who are at increased risk after TAVR.RésuméContexteDes outils sont nécessaires pour dépister les patients exposés à un risque accru à la suite d’un remplacement valvulaire aortique par cathéter (RVAC). Le volume systolique indexé (VSI) est une mesure échocardiographique utilisée dans les cas de sténose aortique à faible gradient. Nous avons vérifié si un faible VSI était un marqueur de risque accru chez les patients présentant une sténose aortique à gradient élevé et avons évalué comment la relation entre le ...

Predictors of Cumulative Health Care Costs Associated with Transcatheter Aortic Valve Replacement in Severe Aortic Stenosis
ConclusionsThis analysis shows that there are 3 distinct phases of cost accumulation from referral to post-TAVR with some potentially modifiable cost drivers in each phase.

Clinical impact of valvular heart disease in elderly patients admitted for acute coronary syndrome: insights from the Elderly-ACS 2 Study
ConclusionsIn a contemporary cohort of elderly patients admitted for ACS, VHD was found in one out of five subjects and had an independent, consistent impact on prognosis.

Outcome Of Patients Undergoing Transcatheter Implantation Of Aortic Valve With Previous Mitral Valve Prosthesis (OPTIMAL STUDY)
ConclusionsTAVR in patients with a previous mitral prosthesis appears safe and feasible, with good hemodynamic results at 30-day and at longer term follow-up.

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.

Transcatheter Versus Surgical Aortic Valve Replacement for Aortic Stenosis in Low-Intermediate Risk Patients: A Meta-Analysis
Conclusions While 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. Teaser In this meta-analysis, there was no difference in 30-day and median 1.5-year mortality outcomes between TAVR and SAVR. However, there was a higher incidence of aortic insufficiency, vascular complications and permanent pacemaker implantation after TAVR compared to SAVR and a higher incidence of atrial fibrillation, acute kidney injury, major bleeding and cardiogenic shock after SAVR compared to TAVR.

Relationship Between Insulin-like Growth Factor Binding Protein-2 and Left Ventricular Stroke Volume in Patients with Aortic Stenosis
Conclusions In this study, we documented that lower IGFBP-2 levels are independently associated with lower SVi, a powerful predictor of worse outcomes in the mild to moderate AS population. Teaser In aortic stenosis (AS) patients, LV remodeling and function vary extensively from one patient to another. Considering the associations between circulating IGFBP-2 and markers of the metabolic syndrome, the aim of the study was to examine the relationship between circulating IGFBP-2 and left ventricle (LV) pump function as measured by stroke volume index in AS patients with preserved LV ejection fraction.

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.

Echocardiography Underestimates Stroke Volume and Aortic Valve Area: Implications for Patients With Small-Area Low-Gradient Aortic Stenosis
Conclusions Echocardiography underestimated LVOTarea, stroke volume, and therefore AVA, compared with MRI. The thresholds based on current guidelines were also inconsistent. In combination, these factors explain > 40% of patients with discordant small-area low-gradient AS.
