To evaluate the awareness and knowledge of the German population regarding diseases in general, a survey of 1446 people aged 60 years or older was conducted in 14 German towns. The focus was on heart valve diseases with special emphasis on aortic valve stenosis (AS). While cancer was the disease that respondents were most concerned about (25.2%), only 3.3% were concerned about heart valve diseases. In this respect, the knowledge was broadly limited: only 7.4% of participants claimed to have some familiarity with heart valve diseases and only 12.5% could correctly describe the symptoms of AS. Even so, 35.0% of the participants could correctly name the number of human heart valves, 71.6% knew at least one therapy option for AS and 30.6% were familiar with transcatheter aortic valve implantation (TAVI). After providing a brief clarification of the prevalence, symptoms and course of AS, 45.6% of respondents were more concerned about the condition, 15.7% wanted to know more about the symptoms of AS and 4.7% even recognized the typical symptoms in themselves. Most of the participants would like to seek more information preferably in discussion with a specialist physician (77.2%), with their general practitioner (43.2%) or using the internet (29.7%). Despite its high prevalence, high morbidity and mortality, the vast majority of the German population were neither concerned nor fully aware of treatment options for AS. There is a strong case for public awareness campaigns that provide better knowledge of AS, and support check-ups that enable timely treatment and the avoidance of unnecessary hospitalization and death.
