Effect of New Cerebral Ischemic Lesions on the Delirium Occurrence After Transcatheter Aortic Valve Replacement
Although only 2% to 5% of patients develop symptomatic stroke following transcatheter aortic valve replacement (TAVR), new cerebral lesions have been detected among the majority of these patients using diffusion weighted magnetic resonance imaging (DWI-MRI), irrespective of access site strategy(1). According to the published reports, new cerebral DWI lesions have been associated with future neurological and cognitive decline; however, the relationship between these lesions and post-operative delirium (POD) following TAVR remains unknown. By means of this study, we aimed to assess the impact of new cerebral DWI lesions on t...

The Challenge of Timing Surgery in Degenerative Mitral Regurgitation Is B-Type Natriuretic Peptide the Solution? ∗
Degenerative mitral regurgitation (MR) with prolapse or flail of mitral leaflets has become the most frequent cause of severe primary MR in Europe and North America (1,2). In its chronic stage, even severe MR is tolerated very well for a surprisingly long time, and patients may remain asymptomatic for years. During this compensated stage of disease, pre-load, afterload, and both contractility and ejection fraction of the left ventricle (LV) remain normal, and the total stroke volume is increased as a result of the compensatory enlargement of the end-diastolic LV volume, which is enabled by an adaptive process of the LV myo...

Fast-track cardiac care for adult cardiac surgical patients.
CONCLUSIONS: Low-dose opioid-based general anaesthesia and time-directed extubation protocols for fast-track interventions have risks of mortality and major postoperative complications similar to those of conventional (not fast-track) care, and therefore appear to be safe for use in patients considered to be at low to moderate risk. These fast-track interventions reduced time to extubation and shortened length of stay in the intensive care unit but did not reduce length of stay in the hospital.

E-093 Contraindications for Radial Access in Endovascular Therapy of Acute Ischemic Strokes
ConclusionAn inherent limitation of transradial access is the restriction to a 6–7 F catheter; however other factors must be considered when identifying cases amenable to radial access.These factors include extreme tortuosity, which not only presents a challenge for radial access, but for all access modalities, and patient height. Patients of above average height or have distal occlusions present a true challenge to the efficacy of radial access as current catheters are limited in length, and thus unable to reach the desired destination. These contraindications are important factors when considering this method of ap...

Cardiovascular highlights from non-cardiology journals
Transcatheter aortic valve implantation in intermediate risk patients Transcatheter aortic valve implantation (TAVI) has had a major impact on both morbidity and mortality in high-risk and inoperable patients with severe aortic stenosis. Robust evidence has supported widespread adoption in this patient group but uncertainty exists as to whether TAVI may also achieve clinical equipoise with surgical aortic valve replacement (AVR) in lower risk groups. In the industry sponsored PARTNER 2 trial, patients deemed at intermediate surgical risk (generally with an STS score between 4 and 8) were randomized to either TAVI with the ...

Cardiac remodelling and function with primary mitral valve insufficiency studied by magnetic resonance imaging
Conclusion CMR provides a reproducible quantitative technique for evaluation of MI, as MIVol and cardiac chamber volumes can be held against diagnostic cut-off values. The Aoflow and peak ejection rate indexed to LVEDV may reveal early LV systolic dysfunction in patients with severe MI. Severe MI is related to lower MI regurgitation volume and fraction than previously believed.

Transcatheter Aortic Valve Implantation Versus Surgical Aortic Valve Replacement for Severe Aortic Stenosis in Patients With Chronic Kidney Disease Stages 3b to 5
Conclusions CKD stages 3b to 5 increases the risk of mortality after TAVI and SAVR. In this subset of patients, SAVR was associated with somewhat better early and late survival. The risk of acute kidney injury was higher after SAVR. These findings suggest that CKD stages 3b to 5 does not contraindicate SAVR. Strategies to prevent severe acute kidney injury should be implemented with either SAVR or TAVI.
