Insights
Infectious endocarditis can lead to rare cardiac complications. This case highlights a myocardial phlegmon causing left ventricular rupture after aortic valve replacement, successfully treated with reoperation.
Area of Science:
- Cardiology
- Infectious Diseases
- Cardiac Surgery
Background:
- Infectious endocarditis valvularis is a serious condition.
- Ventricular wall rupture is a rare but often fatal complication.
Observation:
- A 49-year-old female patient with aortic valve endocarditis underwent valve replacement.
- Post-operatively, she experienced a sudden free left ventricular wall rupture.
Findings:
- Histopathology revealed myocardial infarction due to septic thromboembolism.
- This resulted in a phlegmon-like myocardial appearance.
Implications:
- This case underscores the potential for myocardial phlegmon formation.
- Septic coronary embolism can precipitate cardiac rupture in endocarditis patients.
- Prompt surgical intervention is crucial for survival.
Abstract:
Background Rupture of the cardiac ventricular wall is a rare and essentially lethal complication of infectious endocarditis valvularis. Case Description We report a case of a 49-year-old female patient with infectious endocarditis of the aortic valve. Following aortic valve replacement, the patient developed a sudden free left ventricular wall rupture. Immediate reoperation was successful. Histopathology revealed a myocardial infarction due to septic thromboembolism causing a phlegmonlike myocardial appearance. Conclusion This is a rare case of a myocardial phlegmon with subsequent cardiac lateral wall rupture in the context of an infectious endocarditis with septic coronary embolism.
