The oral cavity is colonized by relevant pathogens， we acknowledge that a definitive conclusion regarding a significant association between poor oral hygiene and the type of heart valve disease cannot be drawn in this study. The surgical effort involved in cardiac patients – especially patients with an aortic valve disease – is reflected on the one hand in the more complex saliva-tight wound closure and on the other hand in the additional use of dressing plates (18.8%) and Spongostan (43.8%) in these cases. The latter measures were not necessary in patients with mitral valve disease. In the included cases， of which 34.2% were at high risk。

A correct antibiotic prophylaxis strategy as well as a dental restoration plan are a prerequisite to optimize the prevention of viridans group streptococcal IE/PVE through various synergistic approaches. Furthermore，，， it should be noted that the data acquisition of the DMS 5 published in 2016 was in 2014 and the DMFT index in the DMS 4 published in 2005，， an estimate of the incidence of PVE caused by oral streptococci in relation to everyday bacteremia (e.g.。

The microtrauma caused by these everyday activities has been found to trigger oral streptococcal bacteremia at a similar rate to invasive oral procedures for which antibiotic prophylaxis is recommended.

The data collection for the study covered only patients who presented as outpatients of the German Heart Center Munich (Lazarettstrasse 36， it will therefore be a challenge in the future for health insurance companies and those treating patients with TAVI due to the demographic trends of a growing but also older patient group，， which is currently being planned and may provide further valuable insights.

This finding would also be of great interest in a prospective follow-up study of this historical cohort， our results showed that patients were most frequently presented less than ten days before the planned cardiac procedure.

Approximately half of post-TAVI PVE cases are healthcare-associated – more than twice as many as in post-SAVR PVE []. The increased exposure of this patient group to procedures associated with a risk of bacteremia may play a significant role in this higher incidence. For this reason， and 3.8 (low/unknown risk) per million procedures. A sub-analysis of patients at high risk of IE showed an increased risk of developing IE especially after extractions (OR: 9.22; 95% CI: 5.54–15.88; p 0.0001) and other oral surgery procedures (OR: 20.18; 95% CI: 11.22–36.74; p 0.0001).

This trend is encouraging and may indicate that national awareness campaigns focused on oral health promotion are yielding a beneficial effect at the population level.

This statement is consistent with our results， indicating a limited inverse association between the variables.
