Percutaneous pulmonary valve implantation (PPVI) has been implemented as a novel alternative strategy to surgical pulmonary valve replacement. However, PPVI has an inevitable limitation: the large right ventricular outflow tract (RVOT) lesions exhibit variable geometry and significant pulmonary regurgitation (PR). To overcome this limitation, bilateral branch pulmonary artery (PA) valve implantations using Melody or Sapien valves have been attempted and have shown a reduction in right ventricular volume with clinical benefits in the intermediate term. Nevertheless, these trials also have constraints of large branch PA size. Recently, a feasibility study using the Pulsta valve (Tae Woong Medical Co, Gyeonggi-do, South Korea) for native RVOTs was reported; the diameter of the Pulsta valve ranges from 18 to 32 mm. Herein, we present a successful percutaneous bilateral branch PA valve implantation using two 32 mm Pulsta valves in a 59-year-old man who showed right heart failure with severe pulmonary regurgitation despite several open heart surgeries for tetralogy of Fallot. The main PA was measured to be 49 mm, and both the right and left PAs were measured to be 30 mm.
