Infective endocarditis update experience from a heart hospital

Area of Science:

• Cardiology
• Infectious Diseases
• Valvular Heart Disease

Background:

• Infective endocarditis (IE) is a serious infection affecting heart valves.
• Distinguishing between natural valve endocarditis (NV) and prosthetic valve endocarditis (PV) is crucial for understanding outcomes.

Purpose of the Study:

• To compare mortality rates and clinical features of IE in patients with natural valves versus prosthetic valves.
• To identify specific risk factors and complications associated with NV and PV.

Main Methods:

• Retrospective study of 50 patients diagnosed with infective endocarditis.
• Analysis of patient demographics, valve type (natural vs. prosthetic), comorbidities, clinical manifestations, and outcomes.

Main Results:

• Overall IE mortality was 44%. NV group: 19% mortality; PV group: 71% mortality.
• Congenital heart disease (bicuspid aortic valve) was more common in the NV group (50% vs. 17%).
• Rheumatic heart disease was more prevalent in the PV group (83% vs. 46%). PV patients had higher rates of embolization to the CNS, spleen, and kidney.

Conclusions:

• Prosthetic valve endocarditis carries a significantly higher mortality risk compared to natural valve endocarditis.
• Distinct underlying pathologies (congenital vs. rheumatic heart disease) are associated with NV and PV.
• Early surgery for late PV and further research into host response are recommended to improve outcomes.
