KEY POINTS. Echocardiography with Doppler is the most widely used imaging modality for the assessment of prosthetic valve function. Compared with a native valve, the prosthetic valve is inherently obstructive, and the type and size of prosthesis determines what is considered normal function. Assessing prosthetic valve function is an integrative ...

A pressure half-time ˃130 msec is the single best indicator of prosthetic obstruction. 2. Taking into account heart rate is not necessary when assessing trans-mitral gradients. 3. Pannus in-growth is more common in the mitral position than with aortic PHVs. 4. A peak velocity ≥2.5 m/sec suggests significant stenosis.
