Initial experience in Mexico with the Evolut ™ R valve with direct aortic Access.

Conclusions: Our center successfully implanted the self-expandable aortic valve Evolut™ through direct aortic for presenting a dissection in transverse aorta with possibilities of embolization. PMID: 31702726 [PubMed - in process]

We describe the case of a 64-year-old man who came to the emergency room due to acute heart failure and intermittent gastrointestinal bleeding. Treatment involves initial correction of anemia and heart failure followed by aortic valve replacement. The prosthesis used depends on the characteristics of each patient and valve replacement allows the resolution of bleeding in most cases. Gastrointestinal bleeding in patients with aortic stenosis is associated with severity of the valve obstruction. A mechanical prosthesis was used with no recurrent bleeding even with the need for lifelong anticoagulation therapy.

CONCLUSIONS: Transfemoral transcaval access proofs to be a feasible and safe TAVI approach for high-risk patients with severe aortic stenosis not suitable for transfemoral or transaxillary/subclavian transarterial access. PMID: 31659987 [PubMed - as supplied by publisher]

ier B Abstract The population of elderly patients comprises a high percentage of women. This population is more vulnerable due to the presence of numerous comorbidities and is, therefore, particularly exposed to the risk of aortic valve degeneration, resulting in aortic valve stenosis whose symptoms are predictors of poor short-term outcomes. In the presence of symptomatic aortic stenosis, the recommended therapeutic option in this vulnerable population is the implementation of transcatheter aortic valve implantation, preferably via the femoral route. The outcomes of this procedure are better in women than in men ...

AbstractBoth transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) have been proven to effectively correct von Willebrand Factor (vWF) pathologies, however there is limited data simultaneously comparing outcomes of both approaches. We prospectively enrolled patients with severe aortic stenosis referred for TAVI (n  = 52) or SAVR (n = 48). In each case, vWF antigen (vWF:Ag), vWF activity (vWF:Ac) and activity-to-antigen (vWF:Ac/Ag) ratio were assessed at baseline, 24 h and 72 h after procedure. VWF abnormalities were defined as reduced vWF:Ac/Ag ratio (

CONCLUSION: Mortality in CS patients due to decompensated severe AS is high, regardless of interventional treatment strategy. Both eBAV and eTAVR seem feasible. As eTAVR is associated with better initial improvements in hemodynamics and simultaneously avoids sequential interventions, it might be favorable to eBAV in select patients. If eTAVR is not available, eBAV might serve as a "bridge" to elective TAVR. PMID: 31611428 [PubMed - as supplied by publisher]

CONCLUSIONS: in patients who are at low surgical risk, TAVI seems to be associated with equivalent mortality up to a median follow up of 2 years compared to SAVR. More data is required before TAVI can be routinely considered as an alternative for SAVR in low risk patients. PMID: 31566571 [PubMed - as supplied by publisher]

AbstractPurpose of ReviewWe conducted a comprehensive and updated overview on complications occurring after transcatheter aortic valve implantation (TAVI) for severe aortic stenosis.Recent FindingsDespite remarkable improvements in patient selection, devices, procedures, and ancillary management, complications may still occur in patients undergoing TAVI. On top of most commonly described adverse events such as death, myocardial infarction, stroke, bleeding, vascular complication, renal failure, pacemaker implantation and residual valve regurgitation, other less common but similarly severe complications may still occur. The...

ConclusionPostprocedural incidence of  ≥ moderate PAR, early all‐cause mortality, early incidence of MI, and midterm all‐cause mortality after TAVI are higher in patients with MS than in patients with no‐MS.

AbstractBackgroundThe aim of this retrospective study was to determine changes in outcomes after surgical aortic valve replacement (SAVR) for aortic stenosis (AS) in Iceland over a 15 ‐year period.MethodsWe included 587 patients who underwent SAVR for AS in Iceland during the period 2002 ‐2016, with a total follow‐up of 3245 patient‐years. Short‐term and long‐term outcomes, 30‐day mortality, and long‐term survival (Kaplan–Meier) were analyzed. Univariate linear regression and univariate and multinomial logistic regression analyses were performed on preoperative and p erioperative variables. Poisson re...
