Incidence and causes of silent and symptomatic stroke following surgical and transcatheter aortic valve replacement: a comprehensive review
Stroke associated with aortic valve replacement in calcific aortic stenosis, either via transcatheter implantation (TAVR) or via surgical replacement (SAVR), is one of the most devastating complications. However, data concerning the clinical impact and incidence of clinical and silent stroke complicating SAVR and TAVR are varying. This comprehensive review of the literature explores the genuine incidence of neurological events after these procedures. Additionally, potential factors responsible for the discrepancies in stroke rates in the current literature are analysed and a lack of uniform neurological definitions and sta...

Impact of Perioperative Stroke on Mid Term Outcomes after Transcatheter Aortic Valve Replacement.
CONCLUSIONS: Stroke increases short term and mid-term mortality following TAVR. Risk prediction for neurologic events in TAVR could aid framework for patient selection, further improving outcomes.

Impact of stroke volume on severe aortic stenosis in patients with normal left ventricular function
ConclusionPatients with LF AS had worse operative and long-term outcomes than those with NF, even though they had preserved LV function.

Outcomes of surgical aortic valve replacement for severe aortic stenosis: Incorporation of left ventricular systolic function and stroke volume index
We sought to a) assess predictors of mortality in consecutive patients with severe aortic stenosis (AS) undergoing aortic valve replacement (AVR) and b) determine if there are differences in mortality, separated on the basis of different AS subtypes and left ventricular stroke volume index (LV-SVI).

Routine cerebral embolic protection in transcatheter aortic valve implantation: rationale and design of the randomised British Heart Foundation PROTECT-TAVI trial
EuroIntervention. 2023 Jan 26:EIJ-D-22-00713. doi: 10.4244/EIJ-D-22-00713. Online ahead of print.ABSTRACTTranscatheter aortic valve implantation (TAVI) is an established treatment for aortic stenosis. Cerebral embolic protection (CEP) devices may impact periprocedural stroke by capturing debris destined for the brain. However, there is a lack of high-quality randomised trial evidence supporting the use of CEP during TAVI. The British Heart Foundation (BHF) PROTECT-TAVI trial will address whether the routine use of CEP reduces the incidence of stroke in patients undergoing TAVI. BHF PROTECT-TAVI is a prospective, open-label...

300 * influence of different pacemaker stimulation modes in patients with ventricular hypertrophy
Conclusion: An increase in the heart rate does not lead to a notable drop in stroke volume postoperatively in left-ventricular hypertrophy; hence a rise in cardiac output can be anticipated up to a rate of 100 bpm. A standardised response in terms of an ideal pacemaker stimulation mode could not be identified.

One-Year Outcomes of Transcatheter Aortic Valve Replacement in Patients With End-Stage Renal Disease
Conclusions Early mortality in patients with ESRD is comparable to previously published data on extreme-risk patients without ESRD, but our data suggest a higher mortality rate at 1 year for ESRD patients, likely due to comorbid conditions. Stroke and major vascular injury are infrequent, and improved valve hemodynamics are maintained at 1 year.

Clinical implications for diffusion‐weighted MRI brain lesions associated with transcatheter aortic valve replacement
Transcatheter aortic valve replacement (TAVR) is increasingly used to treat patients with aortic stenosis deemed high or extreme surgical risk candidates. Despite improved survival and quality of life following the procedure, TAVR is not without its complications. Stroke is a major source of morbidity and mortality in patients undergoing the procedure, with rates similar to and often higher than those associated with surgery. Most studies show a consistent link between TAVR and embolic lesions visualized on diffusion‐weighted magnetic resonance imaging. The question of whether these lesions lead to long‐term cognitive ...

Transapical Aortic Valve Replacement for Severe Aortic Stenosis: Results From the Nonrandomized Continued Access Cohort of the PARTNER Trial.
CONCLUSIONS: Among the 975 patients in the NRCA-TA cohort, rates of major outcomes including death and stroke compared favorably with outcomes of PMA-TA and SAVR patients enrolled in the PARTNER trial. This trend toward improved outcomes may be attributed to improved patient selection, individual centers surmounting the procedural learning curve, and refinements in surgical technique.

Transcatheter aortic valve implantation with the self-expanding Portico ™ valve system in an all-comers population: procedural and clinical outcomes.
CONCLUSIONS: The PorticoTM TAVI system was safe to implant and achieved a high device success rate. With learning curve effects, the device achieves lower rates of PVL and pacemaker implantation and provides adequate clinical and hemodynamic outcomes through 1 year.

Cognition and Cerebral Infarction in Older Adults After Surgical Aortic Valve Replacement
ConclusionsIn high-risk, aged participants undergoing surgical AVR for aortic stenosis, post-operative cognitive dysfunction was surprisingly limited and was resolved by 1-year in most. Post-operative cognitive dysfunction at 4-6 weeks was associated with more and larger acute cerebral infarcts.
