Does valve-in-valve TPVI improve hemodynamics and symptoms in a patient with repaired TOF and prosthetic PV stenosis?
Valve-in-valve TPVI is a safe and effective minimally invasive alternative to repeat surgery for severe prosthetic pulmonary valve stenosis in selected patients with repaired Tetralogy of Fallot.
Abstract Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease, and many patients require reintervention after surgical repair because of right ventricular outflow tract (RVOT) or pulmonary valve (PV) dysfunction. We report the case of a 34-year-old male with repaired TOF and prior prosthetic PV replacement who presented with dyspnea and palpitations. Imaging revealed severe prosthetic PV stenosis with preserved left ventricular function and a suitable RVOT anatomy. The patient underwent successful valve-in-valve transcatheter PV implantation (TPVI) using a 24.5 mm MyVal TM prosthesis through the Python XL sheath. Balloon testing excluded coronary compression, and the gradient decreased from approximately 70-16 mmHg. Postprocedure, the patient showed rapid symptomatic relief and sustained valve performance at 6 weeks. This case underscores the safety and minimally invasive nature of TPVI as an alternative to repeat surgery in selected patients with TOF.
Gautam Swaroop (Thu,) 在法洛四联症修复术后伴人工肺动脉瓣狭窄患者（n=1）中进行了一项病例报告。评估了使用 24.5 mm MyVal 人工瓣膜进行瓣中瓣经导管肺动脉瓣置入术（TPVI）在降低跨瓣压差和缓解症状方面的效果。瓣中瓣经导管肺动脉瓣置入术成功将跨瓣压差从 70 降低至 16 mmHg，并在 6 周时提供了快速的症状缓解。
