Abstract

Background; A well-known, crucial consequence of prosthetic valves that have been surgically or percutaneously inserted is prosthetic paravalvular leak. It usually occurs as a result of insufficient sealing of the prosthetic ring to the native heart tissue, either immediately after surgery or much later as a consequence of infective endocarditis.

Aim and Objectives: The main aim of this study was to compare 3D TEE with 2d TEE regarding Initial diagnosis and localization of PVLs, assessment of size, shape and severity of PVLs and assessment of the feasibility for percutaneous closure.

Subjects and methods: This cross-sectional study was carried out on 30 patients diagnosed with prosthetic mitral paravalvular leaks. The duration of the study ranged from 6-12 months. Result; There was significant increase (over estimation) in size measured by 2D compared to size by 3D (P=0.015) while there was no significant difference between 2D & 3D regarding VC (p>0.05). Regarding site of the leak there was significant association between sites detected by 2D and 3D (p

Conclusion: In the assessment of the morphology of mitral PVL, real-time three-dimensional transesophageal echocardiography is superior to two-dimensional TEE because it provides a detailed description of the number, location, size, and shape of the leak, which is essential for planning and guiding potential corrective techniques.
