Risk of Stroke After Transcatheter Aortic Valve Implantation: Epidemiology, Mechanism, and Management
Conclusions: The overall evidences confirm similar or lower rate of stroke in TAVI versus SAVR. Risk predictors for acute stroke after TAVI are generally related to procedural factors, whereas late stroke is mainly associated with patient characteristics, with a variable impact on cognitive function. The optimal choice for the antithrombotic treatment in TAVI for stroke prevention is yet to be determined. Current data do not support routine use of cerebral embolic protection devices during TAVI.

Insights Into Timing, Risk Factors, and Outcomes of Stroke and Transient Ischemic Attack After Transcatheter Aortic Valve Replacement in the PARTNER Trial (Placement of Aortic Transcatheter Valves) Structural Heart Disease
Conclusions— Risk of stroke or TIA is highest early after TAVR and is associated with increased 1-year mortality. Modifications of TAVR, emboli-prevention devices, and better intraprocedural pharmacological protection may mitigate this risk. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT00530894.

Stroke in patients with prosthetic valve endocarditis : Single-center cohort study in China.
CONCLUSION: Stroke is a common complication in PVE that increases patient mortality. Rheumatic heart disease, double valve replacement, and fungal infection may be risk factors for patients with PVE complicated by stroke. PMID: 31076822 [PubMed - as supplied by publisher]

Stroke after Aortic Valve Surgery: Results from a Prospective Cohort.
CONCLUSIONS: Clinical stroke after AVR was more common than previously reported, more than double for this same cohort in the STS database, and silent cerebral infarctions were detected in over half of patients undergoing AVR. Clinical stroke complicating AVR is associated with increased length of stay and mortality. PMID: 24690611 [PubMed - as supplied by publisher]

Influence of Transcatheter Aortic Valve Replacement Strategy and Valve Design on Stroke After Transcatheter Aortic Valve Replacement A Meta-Analysis and Systematic Review of Literature
ConclusionsOur findings suggest that the risk of 30-day stroke after TAVR is similar between the approaches and valve types. There has been a decline in stroke risk after TAVR with improvements in valve technology, patient selection, and operator experience.

TAVI: Study finds low stroke rates with Medtronic’s CoreValve
A clinical study of nearly 1,000 patients implanted with Medtronic‘s (NYSE:MDT) CoreValve replacement heart valve found a low rate of stroke out to 2 years. The study, published last month in the Journal of the American College of Cardiology, evaluated patients for neurological events over 3 periods after the procedure to implant the CoreValve transcatheter aortic valve implant: Periprocedural (0 to 1 days); early (2 to 30 days); and late (31 to 730 days). Results from the 996-patient trial, “The Incidence and Predictors of Early- and Mid-Term Clinically Relevant Neurological Events After Transcatheter Aortic ...

The Left Atrial Appendage: Target for Stroke Reduction in Atrial Fibrillation.
Abstract A patient with atrial fibrillation (AF) has a greater than 5% annual risk of major stroke, a 5-fold increase compared to the general population. While anticoagulation remains the standard stroke prevention strategy, the nature of lifelong anticoagulation inevitably carries an increased risk of bleeding, increased stroke during periods of interruption, increased cost, and significant lifestyle modification. Many patients with atrial fibrillation have had their left atrial appendage (LAA) ligated or excised by surgeons during cardiac surgery, a decision based largely on intuition and with no clear evidence ...

Perioperative stroke: pathophysiology and management.
Authors: Ko SB Abstract Although perioperative stroke is uncommon during low-risk non-vascular surgery, if it occurs, it can negatively impact recovery from the surgery and functional outcome. Based on the Society for Neuroscience in Anesthesiology and Critical Care Consensus Statement, perioperative stroke includes intraoperative stroke, as well as postoperative stroke developing within 30 days after surgery. Factors related to perioperative stroke include age, sex, a history of stroke or transient ischemic attack, cardiac surgery (aortic surgery, mitral valve surgery, or coronary artery bypass graft surgery), and...

Development and Application of a Risk Prediction Model for In-Hospital Stroke After Transcatheter Aortic Valve Replacement – A Report from the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry
ConclusionsA risk model for in-hospital stroke following TAVR was developed from the STS/ACC TVT Registry and used to estimate site-specific stroke performance. This model can serve as a valuable resource for quality improvement, clinical decision-making, and patient counseling.

Incidence and aetiological mechanism of stroke in cardiac surgery
ConclusionIn our setting, strokes occurring after cardiac surgery are usually small and have a good long-term prognosis. Most of them occur within 2 days, and they are mostly embolic in origin. The incidence of stroke in patients aged 80 and older and undergoing cardiac surgery is twice as high as that of the general population.ResumenObjetivoEstudiar a los pacientes que tuvieron un ictus en el postoperatorio de cirugía cardiaca, para ver la evolución y determinar los factores que influyen en su pronóstico y tratamiento.MétodosEstablecimos un protocolo para la detección precoz de ictus en los pacientes tras cirugía c...

Stroke after Aortic Valve Replacement: The Known and Unknown.
Abstract Stroke following aortic valve surgery is known as a devastating complication and is associated with increased morbidity and mortality.(1) Transcatheter aortic valve replacement (TAVR) has emerged as a valid alternative for surgical aortic valve replacement (SAVR) in both inoperable patients and in those at high risk for surgery; however, the encouraging results were hampered by various complications including stroke. In the pivotal Placement of AoRTic TraNscathetER (PARTNER) trial, the initial stroke rates of TAVR patients were almost double in comparison to patients who underwent SAVR (3.8% vs. 2.1%; p=0...

257 * minimally invasive mitral valve surgery without aortic cross clamping and with femoral cannulation is not associated with increased risk for stroke compared to traditional mitral valve surgery: a propensity score matched analysis
Conclusion: These results suggest an MI fibrillating heart approach for MV surgery was not associated with greater incidence of stroke/TIA. All MI MV surgeries with fibrillatory arrest were performed by surgeons experienced in the MI approach. In the presence of highly experienced surgeons, the MI approach using fibrillatory arrest did not increase risk for perioperative stroke.

Minimally invasive mitral valve surgery without aortic cross-clamping and with femoral cannulation is not associated with increased risk of stroke compared with traditional mitral valve surgery: a propensity score-matched analysis ADULT CARDIAC
CONCLUSIONS A minimally invasive approach for mitral valve surgery on a fibrillating heart was not associated with a greater incidence of stroke/TIA than was median sternotomy. When performed by highly experienced surgeons, the minimally invasive approach with fibrillatory arrest did not increase the risk of perioperative stroke.

Lack of Association Between Extracranial Carotid and Vertebral Artery Disease and Stroke Following Trans-catheter Aortic Valve Replacement
Conclusions The presence or absence of carotid or vertebral artery stenosis was not significantly related to the occurrence of post-TAVR stroke. Routine screening for carotid and vertebral artery disease prior to trans-catheter aortic valve replacement does not appear justified. Teaser In a retrospective cohort study, 19% (n=51) of 263 trans-catheter aortic valve replacement (TAVR) patients had CVD (> 50% stenosis of a carotid or vertebral artery). Post-TAVR stroke occurred in 7% (n=18). All strokes occurred in patients without CVD, and both 30-day mortality rates (10% vs 4%, p=0.11) and overall survival (log-rank t...
