CTICasesRheumatic heart disease involving mitral, tricuspid, and pulmonic valves
Imaging findings
Chest radiograph shows a large left hilar mass corresponding to a giant, dilated main and left pulmonary artery on CT. CT also demonstrates right-sided heart chamber enlargement, marked hypertrophy of the right ventricular infundibulum, and diffuse thickening of the mitral, tricuspid, and pulmonic valves. Surgical pathology confirmed rheumatic valvular disease.
Key takeaways
Rheumatic heart disease classically affects the mitral and aortic valves, but can rarely involve the tricuspid and pulmonic valves. Pulse and volume overload from chronic valvular regurgitation and stenosis can lead to massive dilation of the main and branch pulmonary arteries.
