A transoesophageal echocardiogram revealed thickened valve leaflets consistent with valve thrombosis 1 year after surgical placement of a 33-mm St. Jude Epic bioprosthesis for treatment of severe tricuspid regurgitation (Panel A). Restricted excursion of the valve leaflets resulted in a decreased effective orifice area of 0.63 cm by transoesophageal echocardiography (Panel B). Percutaneous tricuspid valve-in-valve implantation was planned as a bridge to repeat valve surgery. There was an associated small atrial septal defect (ASD) (5 mm) with right-to-left shunting (Panel C). Because of the large thrombus burden and the risk of paradoxical embolism through the ASD, temporary Doppler-controlled occlusion of the ASD using a 6-mm Admiral percutaneous transluminal angioplasty (PTA) balloon was performed (Panel D). A 29-mm Edwards SAPIEN 3 valve was successfully deployed in the surgical valve via femoral venous access (Panel E;see Supplementary material online, Video S1). As a consequence of the instantaneous haemodynamic improvement, inversion of the shunt direction was observed (Panel F). In the absence of haemodynamic relevance, percutaneous ASD closure was not performed. After an uneventful post-operative course, the patient was discharged after 4 days under oral anticoagulation. Echocardiographic follow-up 9 months after the procedure confirmed excellent valve function (mean gradient 4 mmHg, no regurgitation). When planning a tricuspid valve-in-valve intervention, preventive measures for embolic protection should be considered in the presence of an ASD with paradoxical flow (not infrequently encountered in Ebstein patients), particularly in the setting of valve thrombosis or severe calcification.
