  Figure 1 Echocardiography and cardiac computed tomography of subclinical mechanical valve thrombosis. (A) Continuous-wave Doppler of the mechanical aortic valve on postoperative pre-discharge echocardiogram. (B) Continuous-wave Doppler of the mechanical aortic valve on 6-month follow-up echocardiogram. (C) Continuous-wave Doppler of the mechanical aortic valve after intravenous unfractionated heparin therapy for 5 days. (D-F) Low attenuating mass lesions on the right side of the mechanical aortic valve on 6-month follow-up CT. (G-I) Resolution of mass lesions on the right side of the mechanical aortic valve on the follow-up CT after intravenous unfractionated heparin therapy for 5 days.CT = computed tomography.
