Patients with long-standing valvular disease develop a cardiomyopathy which usually improves after disease correction.
Very rare tumors.
Papillary fibroelastoma is the most common primary valvular tumor and frequently occurs on aortic valve cusps.
Myxoma and Hamartoma are less common.
Depending on their locations, valvular tumors can develop fibrin clots, which can subsequently embolize into the systemic or pulmonary circulation.
CT/MR: can detect small tumors and assess their motion during the cardiac cycle.
Caused by endocarditis.
Factors predisposing to endocarditis include intravenous drug use, poor dental hygiene, long-term hemodialysis, diabetes mellitus, mitral valve prolapse syndrome, and prosthetic valves.
The vegetations follow the motion of the valvular cusp to which they are attached.
Frequently the posterior leaflet of the mitral valve is involved.
