Abstract:
The Harmony™ transcatheter pulmonary valve (TPV) is specifically designed to treat severe pulmonary regurgitation in a native or surgically repaired right ventricular outflow tract. To date, no reports have described TPV implantation (TPVI) in patients with prior aortic valve replacement (AVR) using a mechanical valve. Therefore, the risks of technical challenges or complications, particularly coronary compression or device fracture associated with prior AVR, remain unknown. This is the first report of successful TPVI using a Harmony™ TPV in a 52-year-old Asian man diagnosed with tetralogy of Fallot (TOF) who had previously undergone AVR following TOF repair with no associated technical difficulties or complications.
