Emergency aortic valve replacement in active endocarditis with the Björk-Shiley tilting disc valve prosthesis
Insights
Emergency aortic valve replacement can be a life-saving procedure for patients with infective endocarditis and severe heart failure. This intervention addresses acute aortic regurgitation, a common cause of death in such cases.
Area of Science:
- Cardiology
- Cardiac Surgery
- Infectious Diseases
Background:
- Infective endocarditis frequently leads to heart failure, often due to severe aortic valve damage.
- Acute aortic regurgitation is a primary driver of mortality in infective endocarditis.
- Traditional management may be insufficient for patients with intractable heart failure.
Purpose of the Study:
- To evaluate the efficacy of emergency aortic valve replacement in patients with infective endocarditis and severe heart failure.
- To assess the impact of this intervention on survival and clinical outcomes.
- To determine if valve replacement is a viable life-saving option during active endocarditis.
Main Methods:
- Retrospective analysis of three patients with infective endocarditis and severe heart failure.
- Emergency aortic valve replacement using a Björk-Shiley prosthesis.
- Postoperative follow-up to assess survival and condition.
Main Results:
- One patient experienced early postoperative mortality due to myocardial damage and respiratory insufficiency.
- Two patients survived and maintained relatively good condition at 2 years and 6 months post-surgery.
- The procedure was performed in the context of active infective endocarditis.
Conclusions:
- Emergency aortic valve replacement can be a critical, life-saving intervention for select patients with infective endocarditis.
- This procedure can effectively manage acute aortic regurgitation contributing to heart failure.
- Careful patient selection and surgical timing are crucial for favorable outcomes.
Abstract:
Because of severe and intractable heart failure in three patients with infective endocarditis, an emergency replacement of the aortic valve with a Björk-Shiley prosthesis was carried out. Heart failure, which is the most common cause of death in infective endocarditis, was in these cases due to acute aortic regurgitation caused by perforation and other damage of the aortic valve. One patient died in the early postoperative period because of myocardial damage and respiratory insufficiency. The other two survived and are in relatively good condition after follow-up periods of 2 years and 6 months, respectively. The emergency replacement of incompetent valves may be a lifesaving procedure during the course of active endocarditis.
