2021 ESC Guidelines on cardiovascular disease prevention in clinical practice

Developed by the Task Force for cardiovascular disease prevention in clinical practice with representatives of the European Society of Cardiology and 12 medical societies With the special contribution of the European Association of Preventive Cardiology (EAPC) This is only a reference to a fundamental extensive writing Author(s) Source Visseren FLJ,...

Visualization of USPIO-labeled melt-electrowritten scaffolds by non-invasive magnetic resonance imaging

Melt electrowriting (MEW) is a high-resolution fiber-forming technology for the digital fabrication of complex micro-structured scaffolds for tissue engineering, which has convincingly shown its potential in in vitro and in vivo animal studies. The clinical translation of such constructs to the patient requires the capability to visualize them upon implantation...

Fully implantable and bioresorbable cardiac pacemakers without leads or batteries

Temporary cardiac pacemakers used in periods of need during surgical recovery involve percutaneous leads and externalized hardware that carry risks of infection, constrain patient mobility and may damage the heart during lead removal. Here we report a leadless, battery-free, fully implantable cardiac pacemaker for postoperative control of cardiac rate and...

3D blood vessel printing (research)

Scientists in Kiel have developed a innovative 3D bio-printer to create fine blood vessels for bypass implants. "Especially for heart patients who do not have suitable endogenous veins for harvesting a bypass vessel, this new procedure could represent an enormous advance for heart bypass surgery, particularly in terms of patient...

Effect of Implantable vs Prolonged External Electrocardiographic Monitoring on Atrial Fibrillation Detection in Patients With Ischemic Stroke

Question  What is the rate of detection of atrial fibrillation with use of an implantable electrocardiographic monitor for 12 months vs use of prolonged external electrocardiographic monitoring for 30 days after an ischemic stroke? Conclusions and Relevance  Among patients with ischemic stroke and no prior evidence of AF, implantable electrocardiographic monitoring for...

Aortic valve replacement –
TAVI and sAVR in comparison

The German Aortic Valve Registry already counts more than 18 000 implantations of aortic valves. However, long-term comparison of the procedures so far is only possible to a limited extent, mainly because TAVI patients are on average 12 years older than sAVR patients. In accordance with the selection criteria, 13...

Polymeric Materials And Coronary Angioplasty Devices

Cardiovascular diseases are responsible for over 15 million deaths worldwide per year.1 The occlusion of vessels such as the coronary or peripheral arteries hinders the flow of blood to the heart, resulting in heart attacks (myocardial infarction) and often death. Percutaneous transluminal coronary angioplasty (PTCA), a minimally invasive endovascular procedure...

Heart valves that can grow with pediatric patients

There is a need for replacement heart valves that can grow with children. We fabricated tubes of fibroblast-derived collagenous matrix that have been shown to regenerate and grow as a pulmonary artery replacement (in lambs). The tri-tube valves demonstrated reduced calcification and improved hemodynamic function compared to clinically used pediatric...
