Because of the recent symptoms with inappropriate treatment, transesophageal echocardiography (TEE) was performed and revealed a mechanical bileaflet prosthesis in the mitral position with normal lateral occluder motion; however, the medial occluder was fixed due to a thrombus measuring 0.7 cm2 (Fig. 1, clip 1).

Colour flow Doppler across the prosthesis showed accelerated flow (Fig. 2, clip 2).

The Doppler parameters across the prosthesis were calculated and showed the following values: a mean pressure gradient (MPG) of 19 mmHg at a heart rate of 78 beats/min (Fig. 3), a peak early filling velocity (E wave) of 2.4 m/sec, and a pressure half time (PHT) of 354 ms.
