    Abstract:
    OBJECTIVES: The present study evaluated the results of the modified réparation à l'étage ventriculaire (REV) based on the individual anatomical and pathological findings of the patients with an anomalous ventriculo-arterial connection with ventricular septal defect (VSD) and left ventricular outflow tract obstruction. METHODS: We reviewed a series of 24 patients who underwent modified REV between 2005 and 2019. Surgical indications included ventricles and atrioventricular valves suitable for biventricular repair, severe left ventricular outflow tract obstruction (peak gradient >30 mmHg), unrestrictive subaortic VSD and coronary arteries not suitable for reimplantation. RESULTS: The mean follow-up time was 7.0 ± 4.2 years (range 0.5-14.1 years). Kaplan-Meier analyses showed that overall survival was 100% and freedom from any reoperation was 93.3% ± 6.4%. Longitudinal analyses of the available postoperative echocardiographic data showed that the left ventricular outflow tract peak gradient was less than 10 mmHg in all patients (15/15) and the left ventricular ejection fraction was more than 50% in 93.3% of patients (14/15). The right ventricular outflow tract peak gradient was less than 40 mmHg in 73.3% of patients (11/15). CONCLUSIONS: The REV remains an option for selected patients despite the increasing use in recent years of the Nikaidoh procedure and its modifications. The surgical strategy needs to be determined by the specific anatomical and pathological findings of the patient. The modified REV had excellent long-term survival and freedom from reoperation for the treatment of anomalous ventriculo-arterial connection with VSD and left ventricular outflow tract obstruction. The long-term performance of the reconstructed left ventricular outflow tract and right ventricular outflow tract is satisfactory.
