SCIEGATA, Alberto et al. Percutaneous closure of a mitral paraprosthetic leak with an Amplatzer® device. Medicina (B. Aires) [online]. 2012, vol.72, n.5, pp. 431-434. ISSN 0025-7680.
Mitral paraprosthetic leaks are present in 5 to 17% of patients who receive valve replacement surgery. Overall, the defects are single, most of them are located in the postero-medial region of the annulus, and only one third produce a severe reflux. Percutaneous closure by endovascular surgery is a valid therapeutic alternative in patients at high risk for re-operation. The approach depends on the location, size, morphology and relationships or neighboring defects. The procedure must be performed by professionals with experience in the treatment of structural heart disease and in the management of these closure devices. Guidance with three dimensional transesophageal echocardiography is considered essential. A case of a mitral paraprosthetic leak that was closed with an Amplatzer ® device introduced percutaneously from the femoral vein is here presented.
