A 38-year-old male with previous surgeries for an incomplete atrioventricular septal defect successfully underwent percutaneous transcatheter tricuspid balloon valvuloplasty for a deteriorated bioprosthetic valve. Our case highlights the imperative of considering catheter-based minimally invasive therapy for the increasing number of adults with congenital heart disease who may present multiple risks factors for surgery.

Because of advancements in medical and surgical treatment, there has been a decline in mortality from congenital heart defects over the past several decades [1]. As a result, the number of patients with adult congenital heart disease has increased over time [2,3]. Most patients with adult congenital heart disease underwent several surgeries during childhood. In some cases, surgical or catheter interventional treatment in adulthood is recommended because of sequelae or remote-term complications [4,5]. In some cases, catheter intervention is preferable to surgery because the patient is considered a high-risk candidate. In our report, we describe the first case of percutaneous transcatheter bioprosthetic tricuspid balloon valvuloplasty for a patient with adult congenital heart disease.
