…to enter the diseased aortic media. Blood then propagates along the wall, creating a true lumen and a false lumen separated by an intimal flap…

…bacterial infection engages the heart valves and this is a serious condition. The focus of infection on the flap is called vegetation. As a rule…

…haemorrhage within the aortic media without an identifiable communication between the aortic lumen and the haematoma and without a visible intimal flap or false lumen…

…increasing frequency of hospitalizations and visits for heart failure without disease recognition in the 3 years preceding diagnosis is also a notable red flag [8]…

…chest discomfort requires a systematic differential diagnosis, as the syndrome associated with ischemic heart disease is broader than chest pain itself, encompassing symptoms like tightness…
