Cardiac imaging of prosthetic valve dysfunction by transesophageal echocardiography
نویسنده
چکیده
Prosthetic heart valve (PHV) replacement replaces a heart disease with another one. There is no ideal prosthetic heart valve. All of the prosthetic heart valves need to be followed by caution. PHV diseases (PHVD) includes a group of pathologic processes like prosthetic valve obstruction, thromboembolism and regurgitation. Correct diagnosis and treatment of these pathologic situations will decrease mortality and morbidity due to PHVD. Knowledge about PHVD and correct usage of cardiac imaging modalities for the diagnosis, make possible to solve the problem. 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 prosthetic heart valve problems.

Evaluation of transesophageal echocardiography in detecting cardiac sources of emboli in ischemic stroke patients
Background: Embolus is one of the causes of ischemic stroke that can be due to cardiac sources such as valvular heart diseases and atrial fibrillation and atheroma of the aorta. Transesophageal echocardiography (TEE) is superior in identifying potential cardiac sources of emboli. Due to insufficient data on TEE findings in ischemic stroke in Iran, the present study was done to evaluate TEE in...

Aortic valve replacement accounts for a significant portion of cardiac surgeries in the United States. Despite advances in prosthetic heart valve design, surgical technique, and postoperative care, complications after aortic valve replacement remain a leading cause of morbidity and mortality. Routine surveillance of prosthetic heart valves with transthoracic echocardiography (TTE), transesophag...
متن کاملDetection of prosthetic valve strands by transesophageal echocardiography: clinical significance in patients with suspected cardiac source of embolism.
OBJECTIVES The purpose of this study was to determine how frequently prosthetic valve strands are associated with prosthetic mitral and aortic valves, as detected by transesophageal echocardiography, and to assess their significance in relation to clinical cardioembolic events. BACKGROUND Strands attached to prosthetic mitral valves are a recently described finding of uncertain clinical signi...
متن کاملRetrieval of a leaflet escaped in a Tri-technologies bileaflet mechanical prosthetic valve.
The escape of the prosthetic heart valve disc is one of the causes of prosthetic dysfunction that requires emergency surgery. The removal of the embolized disc should be carried out because of the risk of a progressive extrusion on the aortic wall. Several imaging techniques can be used for the detection of the missing disc localization. In this report we describe a 32-year-old man who underwen...
متن کاملNovel Application of Tissue Doppler Imaging
Tissue Doppler imaging was used with transthoracic and transesophageal echocardiography to determine its clinical usefulness beyond visualization of ventricular wall motion. Thirteen novel applications were found: acoustically difficult transthoracic studies, thrombus, mitral chordal motion, shunt detection using saline contrast, spontaneous echo contrast, intra-aortic balloon pump position and...
