Management and Outcome of Acute Ischemic Stroke Complicating Transcatheter Aortic Valve Replacement.

Background: Despite advances in transcatheter aortic valve replacement (TAVR), periprocedural acute ischemic stroke remains a concern.

Objectives: The aims of this study were to investigate acute ischemic stroke complicating TAVR (AISCT) and to describe the indications and outcomes of interventions to treat AISCT.

Methods: An international multicenter registry was established focusing on AISCT within 30 days of TAVR.

Percolation and tortuosity in heart-like cells.

In the last several years, quite a few papers on the joint question of transport, tortuosity and percolation have appeared in the literature, dealing with passage of miscellaneous liquids or electrical currents in different media. However, these methods have not been applied to the passage of action potential in heart fibrosis (HF), which is crucial for problems of heart arrhythmia, especially of atrial tachycardia and fibrillation. In this work we address the HF problem from these aspects.

Origin of post-ictal and post-anesthesia adverse effects and possibly of SUDEP.

The origin of post-ictal malfunctions is debatable. We want to propose a novel idea of a cause of these adverse results occurring following epileptic seizures and anesthesia. Previously we have put forward the idea that epileptic seizures termination is caused by the function of the glymphatic system in the brain.

Explaining recent postictal epilepsy EEG results by the G-lymphatic clearance hypothesis.

Two recent postictal EEG measurements demonstrate somewhat conflicting results of epileptic behavior clearance in different brain parts. Both measurements observed two modes of seizure cessation, an abrupt and a gradual one, with slightly different statistics. No explanations were given for the appearance of these modes.
