A patient with endocarditis presented with prosthetic tricuspid valve stenosis. Echocardiography revealed a large vegetation and an unusual interatrial septum bulge during diastole.
Area of Science:
- Cardiology
- Medical Imaging
- Infectious Diseases
Background:
- Endocarditis can affect prosthetic heart valves, leading to complications like stenosis.
- Tricuspid valve (TV) prosthesis dysfunction requires accurate diagnostic methods.
Observation:
- A large vegetation was observed within the TV prosthesis.
- The vegetation obstructed the TV prosthesis orifice during diastole.
Findings:
- The patient exhibited tricuspid valve stenosis without regurgitation.
- A rare echocardiographic finding of interatrial septum bulging toward the left atrium in diastole was noted.
Implications:
- This case highlights a specific echocardiographic sign associated with prosthetic valve endocarditis.
- Understanding these findings can improve the diagnosis and management of complex cardiac conditions.
