Abstract
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.

Summary
Prosthetic heart valves (PHV), used for many years in the treatment of valvular heart diseases. If it is necessary, diseased heart valves can be replaced with mechanical valves, or bioprosthesis, which is generally derived from pig pericardium. Prosthetic valve selection should be made with caution, depending on the patient’s clinical characteristics. No matter how accurate selection, severe problems may occur during the follow-up of prosthetic valves. While some of these problems inevitably, some of them can be prevented effectively by medical treatment. TEE findings in PHV diseases, TEE imaging characteristics of special PHVD and clinical guidance of TEE in prosthetic heart valve problems
