Surgical implantation of a
mechanical or biological prosthetic heart valve (PHV) with original structure
and hemodynamics is conventional treatment of valvular heart disease. All
kinds of prosthetic valves are stenotic comparing with native valves. They
should be imagined by being aware of their specific properties. PHV diseases (PHVD) describes situations like obstruction,
thromboembolism and regurgitation which also
have characteristic images. Determining the cause and severity of PHVD
is mandatory for selection of treatment method. Knowledge about PHVD and correct
usage of cardiac imaging methods facilitate diagnosis. Most helpful
diagnostic test for PHVD is transesophageal echocardiography (TEE). The aim
of this review is to describe TEE in PHVD, TEE imaging characteristics of some
special PHVD and clinical guidance of TEE in PHV problems.
