Surgical aspects of bacterial endocarditis

Area of Science:

• Cardiology
• Infectious Diseases
• Cardiac Surgery

Background:

• Bacterial endocarditis poses significant risks, often necessitating surgical intervention.
• Previous history of bacterial endocarditis requires careful management and monitoring.

Purpose of the Study:

• To evaluate the outcomes of surgical treatment for bacterial endocarditis.
• To assess the efficacy of valve replacement and emergency operations in endocarditis patients.
• To determine the role of surgery in managing prosthetic valve infections.

Main Methods:

• Retrospective analysis of 40 patients with bacterial endocarditis undergoing surgery between 1967 and 1971.
• Categorization of patients into elective valve replacement, emergency operation for heart failure, and operations for prosthetic infection groups.
• Follow-up assessment of survival rates and long-term outcomes.

Main Results:

• Overall survival rate of 78% at four years and nine months post-operation.
• Elective valve replacement group: 4 hospital deaths, 1 late death (14.8% mortality).
• Emergency operation group for heart failure: 1 late death (14.3% mortality).
• Prosthetic infection group: 2 hospital deaths (33.3% mortality).

Conclusions:

• Elective valve replacement is a viable surgical option for selected bacterial endocarditis patients.
• Emergency surgery is critical for managing intractable heart failure during active infection.
• Surgical intervention is essential for eradicating infection on cardiac prostheses.
