Summary
Early diagnosis and prompt antibiotic treatment, guided by bacterial identification and echocardiography, are crucial for improving the poor prognosis of infectious endocarditis (IE) and prosthetic valve endocarditis (PVE).
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Diagnostics
Background:
- Infectious endocarditis (IE) presents a complex clinical challenge with variable early symptoms.
- Complications and premature antibiotic use can obscure typical IE presentations, complicating diagnosis.
Purpose of the Study:
- To detail the clinical picture, diagnostic methods, and prognosis of infectious endocarditis.
- To review experiences with conservative therapy and valve replacement for IE.
- To analyze outcomes for prosthetic valve endocarditis (PVE).
Main Methods:
- Review of clinical experience at Hanover Medical School.
- Emphasis on echocardiography (M-mode, 2D, esophageal) for vegetation detection.
- Analysis of blood cultures for bacterial diagnosis.
Main Results:
- Echocardiography detects vegetations in approximately 80% of IE cases.
- Early prosthetic valve endocarditis (PVE) has decreasing incidence but high mortality despite reoperation.
- Late PVE resembles native valve IE and may respond to medical treatment, especially with biological valves.
Conclusions:
- Prognosis in IE remains poor, heavily influenced by early diagnosis and timely antibiotic therapy.
- Positive bacterial diagnosis is essential for effective antibiotic treatment in IE.
- Prompt management is key to improving outcomes for both native and prosthetic valve endocarditis.
