Infective Endocarditis of the TAVI Prosthesis: Emerging New Challenges

Area of Science:

• Cardiology
• Infectious Diseases
• Surgical Innovation

Background:

• Transcatheter aortic valve implantation (TAVI) is an increasingly common procedure for severe aortic valve stenosis.
• TAVI endocarditis, a serious complication, poses diagnostic and therapeutic challenges.
• Early diagnosis and intervention are crucial for managing TAVI endocarditis.

Purpose of the Study:

• To report a case of TAVI endocarditis caused by Streptococcus bovis.
• To discuss the diagnostic and management challenges associated with TAVI endocarditis.
• To emphasize the effectiveness of surgical intervention in TAVI endocarditis.

Main Methods:

• Case report of a 74-year-old patient with TAVI.
• Diagnostic workup including blood tests and transesophageal echocardiogram.
• Surgical explantation of the TAVI prosthesis and aortic valve replacement.

Main Results:

• Transesophageal echocardiogram revealed a large vegetation on the TAVI prosthesis.
• Surgical findings showed extensive damage to the TAVI device.
• Microbiological analysis of the explanted TAVI identified Streptococcus bovis.
• The patient experienced a full recovery after surgery.

Conclusions:

• TAVI endocarditis can present with severe complications even with less aggressive pathogens.
• Early surgical intervention is critical for successful treatment of TAVI endocarditis.
• Increased TAVI procedures necessitate heightened awareness and management strategies for endocarditis.
