Transcatheter heart valve selection in patients with low ejection fraction and aortic stenosis
ConclusionThe choice of THV in patients with severe AS and systolic dysfunction must be weighed on a case-by-case basis.

Cerebral Embolic Protection in Transcatheter Aortic Valve Replacement: A Meta-Analysis of Randomized Clinical Trials
Transcatheter aortic valve replacement (TAVR) has become a mainstay treatment option for most patients with severe symptomatic aortic stenosis. Although the majority of TAVR-related complications have decreased overtime, stroke rates remained relatively unchanged.1,2 Hence, numerous efforts have been devoted to developing effective strategies to mitigate the risk of post-TAVR strokes. We performed an updated meta-analysis to assess the efficacy and safety of cerebral embolic protection (CEP) during TAVR.

Long-term changes in coronary physiology after aortic valve replacement
Conclusions: CFR in the LAD increased significantly at follow-up although global hyperaemic flow and minimal microvascular resistance remained unchanged. Thus, a decrease in resting flow was the cause of CFR improvement. CFR improvement was associated with reduction in LVSW.PMID:36239118 | DOI:10.4244/EIJ-D-22-00621

Systemic blood pressure in severe aortic stenosis: Haemodynamic correlates and long ‐term prognostic impact
ConclusionsIn severe AS patients, lower MAP reflects lower systemic vascular resistance and valvulo-arterial impedance, which may help to preserve stroke volume and filling pressures despite reduced left ventricular performance, and lower MAP is a predictor of higher long-term post-AVR mortality.

Cerebral Embolic Protection Does Not Prevent Stroke in TAVR
FRIDAY, Sept. 30, 2022 -- The use of cerebral embolic protection (CEP) does not have a significant impact on the incidence of periprocedural stroke among patients with aortic stenosis undergoing transfemoral transcatheter aortic-valve replacement...

Investigation on Imaging Features and Clinical Significance of Cardiac CT in Comprehensive Evaluation of Aortic Valve and Root before Percutaneous Aortic Valve Replacement
This study retrospectively includes patients with severe aortic stenosis who underwent TAVR with routine computed tomography. Based on CT images, the determination and grouping of bicuspid aortic valve and tricuspid aortic valve were completed. Thirteen cross-sectional levels of the aorta-iliac-femoral vascular access were completed. The results showed that 3 people had stroke (17.6%) and 5 people had myocardial infarction (29.4%) during the follow-up period. Atrial fibrillation occurred in 5 patients (29.4%), permanent pacemaker implantation was performed in 1 patient (5.9%), and acute kidney injury occurred in 7 patients...

Concomitant anaortic OPCAB and transfemoral TAVR for high ‐risk patients: A case series
ConclusionsCombined anaortic OPCAB and transfemoral TAVR is a safe and feasible approach to treating concomitant extensive coronary artery disease and severe aortic stenosis. The aortic no-touch technique provides benefits in the elderly high-risk patients by reducing the risk of postoperative myocardial infarction and cerebrovascular stroke.

Inter-racial differences in patients undergoing transcatheter aortic valve implantation
Conclusions There were significant differences in baseline and procedural factors among Asian and non-Asian patients who underwent TAVI. Observed inter-racial differences in clinical outcomes were largely explained by baseline differences in clinical, anatomical and procedural factors. Trial registration number NCT03826264 (https://wwwclinicaltrialsgov).

Clinical and neurocognitive outcomes after transcatheter aortic valve implantation (TAVI) with cerebral protection: initial experience with a novel dual-filter device in Southeast Asia
CONCLUSION: In this early Asian experience of TAVI under cerebral protection, the filter device was successfully deployed in 95% of patients, with 100% procedural success. There were no filter-related complications and no stroke or mortality at 30 days. Overall cognition was preserved, although increased age was associated with a decline in AMT score.PMID:36043277 | DOI:10.11622/smedj.2022030
