Determinants of the Progression and Outcome of Mitral Regurgitation

Mitral regurgitation (MR) is one of the most frequent valve lesions, both in North America and in Europe, and its prevalence is increasing with the aging of the population. Organic Mitral Regurgitation (OMR) and Ischemic Mitral Regurgitation are the 2 main categories of MR. Organic or primary MR is caused …

CT Perfusion Added to CT Angiography (PERFeCT)

Background In the differential diagnosis of unstable angina versus non-anginal chest pain, an exercise test is often the modality of choice for further investigation. However, in a substantial number of patients exercise testing is less informative, because of insufficient exercise capacity or pre-existing ECG-abnormalities. In patients with low pretest probability …

Frequent Cuff Inflations May Disrupt the Accuracy of 24-hour Ambulatory Blood Pressure Monitoring

24-hour ambulatory blood pressure monitoring (ABPM) is superior to office blood pressure (BP) for assessing cardiovascular risk. On the other hand, repeated cuff inflations during ABPM can cause discomfort and reduced quality of sleep. A high frequency of measurement during ABPM might result in erroneously high BP measurement, incorrect hypertension …

Prospective Evaluation for Hybrid Cardiac Procedures

Multidisciplinary team-approach in order to offer personalized treatments represents the emerging mainstream in cardiovascular medicine. "Hybrid operative rooms" allow to offer selected heart-disease patients truly "tailored" operations. This study wants to evaluate the effectiveness and safety of Hybrid Procedures in cardiac patients in three subgroups of patients: Hybrid coronary revascularization …

Risk Stratification Post TAVI Using TEG

Transcatheter aortic valve implantation (TAVI) has become the standard of care in elderly patients at increased risk for surgical aortic valve replacement . However, the optimal antithrombotic strategy post TAVI is still unclear. Current European guidelines recommend dual antiplatelet therapy (DAPT) for 3 to 6 months.The prevalence of subclinical leaflet …

Early Cardiac Magnetic Resonance Imaging in Suspected Non-ST-Elevation Myocardial Infarction

Background and rationale: Evaluating patients with acute chest pain, elevated high-sensitive cardiac troponin (hs-cTn) levels and non-diagnostic electrocardiogram (ECG), i.e. suspected non-ST elevation myocardial infarction (MI), is a daily challenge. Although contemporary hs-cTn assay-based algorithms have greatly facilitated clinical decision-making, still one-quarter of patients is categorized as 'observe' group and …

Pacing to Maintain Physiologic Ventricular Activation

Right ventricular pacing causes ventricular dyssynchrony and may be associated with impaired outcome. In the last decade, several approaches for more physiological pacing became available and were implemented in the latest guidelines. However, compared to conventional device implantation, cardiac resynchronization, His bundle pacing and left bundle area pacing remain demanding …

Internal Jugular Vein and Spinal-induced Hypotension

The study aims to assess internal jugular vein ultrasound derived measurements and indices prior to spinal anesthesia in elderly population who fulfills predetermined inclusion criteria and might greatly benefit from an appropriate hemodynamic control during orthopedic surgery. Therefore, it is evaluated the diagnostic performance of these indices in predicting spinal-induced …
