Transcatheter Aortic Valve Replacement (TAVR) Effects on Cardiac Conduction System (TAVR-HBE)

This is a prospective observational study, the purpose of which is to: Characterize response of the AV conduction system to TAVR with various prostheses by recording continuous His bundle electrograms during valve placement. Correlate preprocedure ECG features with changes in AV nodal and infranodal conduction during placement of the valve …

Monitoring Neurological Deterioration in Anaesthetised Patients With Electroencephalogram (EEG)

The incidence of perioperative stroke in the non-cardiac, non-vascular, non-neurological high risk surgical population is 2%. It is higher (~5%) for cardiac surgery and carotid endarterectomy patients, with a stroke associated mortality of up to 60%. These patients could be immediately treated if their condition was detected on time. Currently, …

Validation of a Non-invasive Assessment of Central Venous Oxygen Saturation by Using MRI

BOLD measured with MRI may be a useful noninvasive method for the assessment of right ventricular O2 saturation. A validation of this method against right heart catheterization has not been fully performed. Whether the method may have a diagnostic and prognostic role in chronic heart failure patients is unclear.

Early Detection of Cardiac Amyloidosis

Due to a lack of therapeutic options, the diagnosis of cardiac (wt)-ATTR amyloidosis was for a long time overshadowed by other diseases and therefore was or still is often diagnosed with considerable delay. The aim of the study is to estimate the prevalence of cardiac amyloidosis among patients with mild-to-moderate …
