Quantificação de insuficiência protética mitral por diferentes métodos de avaliação pela ecocardiografia transesofágica

Abstract

TEE correctly identified angiographic severe mitral prosthesis regurgitation, mainly by the presence of systolic flow reversal in pulmonary vein and subjective assessment. The estimation of severity of the prosthetic MR by absolute or relative jet area seems to be limited and should be used with caution due to eccentricity of the regurgitant jet, frequently seen in mitral prosthesis dysfunction.

Echocardiographic Assessment of Prosthetic Valves

“…The regurgitant jet area may be used with caution, as it may reflect severity if it is central in origin. A large and wide jet with 8 reflects significant MR [ 63 ]. Additionally, vena contracta of 6 mm reflects a large regurgitant volume.…”
