Performance of Bioprosthetic Aortic Valves

Comparison of Long-term Performance of Bioprosthetic Aortic Valves in Sweden From 2003 to 2018 Importance  The performance of bioprosthetic aortic valves is usually assessed in single valve models or head-to-head comparisons. National databases or registries offer the opportunity to investigate all available valve models in the population and allows for a...

smartphones may affect implanted pacemakers

Current smartphones may affect the function of implanted pacemakers/defibrillators. The hypothesis: Compared to previous devices, newer smartphones have more centrally and circularly installed magnets. These allow fast wireless charging of the smartphone. This could impair the functioning of pacemakers and defibrillators more than before. The researchers found influences of the...

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...

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...
