Abstract
Background
Right ventricular outflow tract (RVOT) stenting has emerged as an initial palliation of patients with Tetralogy of Fallot (ToF) type lesions. There is little published data on feasibility of pulmonary valve sparing stenting and whether this could facilitate valve sparing surgery at the time of subsequent surgical correction.
Objectives
This study sought to assess growth of the pulmonary valve annulus after valve sparing stenting of the RVOT in ToF type lesions and whether the pulmonary valve could be preserved at the time of surgical repair.
Methods
This was a retrospective, single-centre study of 96 nonrandomized, consecutive palliated Fallot patients over a 16-year period. Pulmonary valve growth was assessed in patients undergoing valve sparing RVOT stenting (46). We also collected data on patients who had valve crossed and used stent diameter as surrogate marker for valve.
Results
Pulmonary valve Z-score in the valve spared group improved significantly from median -4.1 (interquartile range [IQR]: -5.2- -3.3) to median -2.87 (IQR: -3.5 - -2.1), P
