RESUMO
Re-operation of a tricuspid bioprosthesis carries high morbidity and mortality, especially when carried out with other concomitant valvular heart surgery. Concurrent transcatheter valve implantation has evolved as an alternative option. Here we report on a 77-year-old lady who suffered from symptomatic severe recurrent stenosis of a tricuspid bioprosthesis (Sorin Pericarbon More, 27) and moderate to severe aortic stenosis (AS) who was declined for redo open heart surgery as it was deemed very high risk. We used a 3D customised printed right heart model for pre-OT rehearsal. Percutaneous V-in-V TVR using a 26 mm Edwards SAPIEN 3 was performed under general anaesthesia via the right femoral vein and showed a satisfactory result in one single attempt. We also evaluated the necessity of aortic valve intervention in detail before and after V-in-V TVR. After confirmation of severe AS, a 26 mm Medtronic CoreValve Evolut R was deployed in the non-calcified rheumatic aortic valve without any predilatation or post-dilatation via the right femoral artery. No significant gradient or leakage was seen. This case shows the feasibility and safety of concurrent transfemoral V-in-V TVR and TAVI. Rehearsal using a 3D printed model helped to increase the accuracy and success rate of the procedure. The transcatheter approach allows detailed haemodynamic assessment after each valvular intervention in the case of multiple valve interventions.
