Arteria lusoria is an anatomical variety of the aortic arch occurring in approximately 1-2% of the population. It consists in the congenital absence of the brachiocephalic trunk and a separate outlet from the aortic arch of the right subclavian artery. In the case of aortic arch pathology (aneurysm, dissection) in patients with this anomaly, technical treatment options are very limited, especially with modern minimally invasive methods. On January 12 and 13, specialists from our University performed the world's first two surgeries of the implantation of stent-grafts into the aortic arch with four branches in patients with arteria lusoria.

Chest pain is one of the most common reasons patients present to the hospital. For the patient, it means fear and uncertainty. Meanwhile, the physician faces a rapid decision: are we dealing with a myocardial infarction, a life-threatening condition, or another, often much less dangerous, cause of the symptoms? The problem is that in the early stages, the symptoms can be very similar. And in myocardial infarction, time works against us. That is why in our project we are searching for a new warning signal, writes Ewelina Błażejowska, MD, a PhD candidate at the 1st Chair and Department of Cardiology, UCK WUM.
