Multimodality imaging of multivalvular endocarditis after transcatheter aortic valve replacement

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Transcatheter aortic valve replacement (TAVR) is a key treatment for severe aortic stenosis in high-risk patients.
• Endocarditis post-TAVR is infrequent but poses diagnostic and management challenges due to patient comorbidities.

Observation:

• A case study presents a patient with suspected endocarditis following TAVR.
• Initial diagnosis was made using cardiac computed tomography angiography (CCTA).

Findings:

• CCTA revealed vegetations and perivalvular involvement characteristic of TAVR endocarditis.
• Transesophageal echocardiogram confirmed the diagnosis.

Implications:

• This case highlights the effectiveness of CCTA in diagnosing TAVR endocarditis.
• Cardiac CT imaging is valuable for visualizing complications like vegetations and perivalvular spread in TAVR patients.
