Surgical remodeling techniques for the right ventricle during pulmonary valve replacement

Pulmonary valve dysfunction following transannular patch repair of Tetralogy of Fallot can result in right ventricular (RV) dilation, potentially leading to lifelong complications. This study describes three surgical RV remodeling techniques aimed at addressing RV dilation during pulmonary valve replacement (PVR). Early postoperative evaluations demonstrated significant reductions in RV outflow tract diameters and improvement in QRS duration. These findings indicate that incorporating RV remodeling techniques during PVR may help mitigate the progression of RV dysfunction. Long-term follow-up is necessary to confirm these preliminary results.
