RESUMO

BACKGROUND: Mitral paravalvular leak (PVL) is a potential complication of surgical valve replacement procedures. Real-time 3D transesophageal echocardiography (RT-3DTEE) has emerged as an efficient tool for providing essential information about the anatomy of mitral PVLs compared with 2DTEE findings. The purpose of this study was to evaluate the utility of RT-3DTEE in the assessment of mitral PVLs. METHODS AND RESULTS: The 3D characteristics of PVLs were recorded and compared with 2D findings. We included 34 consecutive patients with clinical suspicion of mitral PVL in the study. Mitral PVLs were detected in 26 patients (76%); 26 PVLs were identified by 2DTEE and 37 by RT-3DTEE. Moderate or severe mitral regurgitation was present in 23 patients (88%). The most common PVL locations were the septal and posterior regions. The median PVL size measured by RT-3DTEE was 7 mm long×4 mm wide. The median vena contracta of defect measured by 2DTEE and RT-3DTEE was 5 mm and 4 mm, respectively. The median effective regurgitant orifice area of defect measured by RT-3DTEE was 0.36 cm(2). The defect types were "oval" (54%), "round" (35%), "crescentic" (8%) and highly irregular (3%). CONCLUSIONS: Compared with 2DTEE, RT-3DTEE provided detailed descriptions of the number, location, size and morphology of PVLs, which is essential for planning and guiding the potential corrective techniques.

RESUMO

Presentamos el caso de una paciente de 53 años portadora de una prótesis mitral que fue ingresada en situación de insuficiencia cardíaca. Tras efectuarse el diagnóstico de trombosis protésica se planteó la disyuntiva terapéutica entre el tratamiento quirúrgico y el trombolítico. Debido al elevado riesgo quirúrgico, fue tratada con r-TPA (pauta acelerada), obteniendo una respuesta satisfactoria e inmediata (AU)
