Predicting the Future: Tetralogy of Fallot Will Be Primarily Treated with Catheter Based Intervention Within Two Decades. Surgeon’s Perspective

摘要

Interventional cardiology has made extraordinary advances over recent years, but most are still limited to addressing single intracardiac or valvular?lesions. This debate considers whether complete interventional repair of more complex congenital defects might become achievable. Tetralogy of Fallot (ToF) is probably the first candidate where complete interventional repair might be achieved—given that various components of the defect have already been successfully addressed—albeit as either a palliative intervention (RVOT stenting) or to address the sequelae of standard surgery (percutaneous PVR). This article considers the challenges that would need to be overcome in terms of the morphology of the condition, the age limitations, and the necessary technological advancements that would be required—while setting these against the benchmark of current surgical outcomes and the parallel progress that is being developed in surgical correction. While complete interventional repair of ToF may still be beyond current techniques, a hybrid approach between surgeons and intentional cardiologists can strive to create a life-long paradigm of care that minimizes the need for surgery and focuses on the maintenance?of a?healthy right ventricle, such that patients born with ToF can achieve normal life expectancy.
