A NOVEL SURGICAL APPROACH USING CONTRACTING BAND TO IMPROVE RIGHT VENTRICLE EJECTION FRACTION FOR PATIENTS WITH REPAIRED TETRALOGY OF FALLOT, A PATIENT-SPECIFIC CMR-BASED MODELING STUDY

摘要

Patients with repaired Tetralogy of Fallot (ToF) account for the majority of cases with late onset right ventricle (RV) failure. The current surgical approach, which includes pulmonary valve replacement/insertion (PVR), has yielded mixed results [1-2]. A new surgical option placing an elastic band in the right ventricle is proposed to improve RV cardiac function measured by ejection fraction (EF).
