Objective: The aim of this study is to investigate the early and mid term results of one and a half ventricle repair. Materials and Methods: Pathological and demographic data, prior palliative operations selection criteria and operative properties of six patients with right ventricular hypoplasia undergoing one and a half ventricle repair were investigated. Patients were followed for mean 55.6±18.9 months by clinical and echocardiographic examinations. Results: One patient died in the early-mid term follow-up period. The intensive care unit and hospitalization mean time were 2.8± 0.83 and 11.25± 6.55 days respectively. One patient had recurrent pleural effusion; she also had epicardial permanent pace implantation for atri- oventricular block within the postoperative second month. Another patient was reoperated for important tricuspid and pulmonic valve regurgitation at postoperative 3rd year. All other patients were followed with medical therapy in NYHA class I-II status. Conclusion: The early and mid-term results of one and a half ventricle repair seem to be acceptable. This method can be a good alterna- tive to Fontan repair in suitable patients.
