Early outcome of window like repair and valveless RV to PA connection for type one truncus arteriosus

Back groundRepair of truncus arteriosus represents a surgical challenge. Many technical modifications were added to improve the surgical outcome, decrease complications and decrease the incidence of re operations especially regarding the RV to PA connections with the consideration of absence or limited number of valved biological conduits in most of our centers in Egypt.Patients and methodsOver the last six months 4 patients with TA type 1underwent total surgical repair with window like technique (without separation of the short main pulmonary trunk from the main trunk) and valveless RV to PA connection except one that was done using contegra due to severe PH as the patient was 6 months old.ResultsEarly results of this limited number of patients’ reveals satisfactory results with no in hospital mortality, acceptable ICU and hospital stay and early post-operative echocardiographic study apart from clinically tolerated moderate PR.ConclusionWindow like repair of TA and valveless RV to PA connection reveals satisfactory early outcome and considered as good alternatives for the classic techniques utilizing valved biological conduits especially when limited resources are obstacles for repair of this category of complex lesions
