A Complete transposition of the great arteries combined with VS.D, A.S.D, dextrocardia, and P~S is a ram congenital anomaly. The patient was a 10 year old female whose complaints were frequent URI, exertional dyspnea, and cyanosis at rest since birth. Cheat X-ray films showed Dextrocardia; situs inversus, moderate cardiomegaly, and Characteristic egg-shaped heart shadow. E.K.G, Echocardiography, Cardiac Catheterization, and Angiocardiography were performed. Open heart Surgery was done under diagnosis of d-TGA, Dextrocardia, V.S.D , A.S.D, and P.S. At the time of Operation, Dextrocardia, T.G.A, Secundum type A.S.D. [2.0x2.0cm. in diameter], V.S.D. type II [1 .5cmxl .5cm in diameter], and pulmonary valvular stenosis were noted. Mustard operation using pericardial Baffle in the atrium for T.G.A. was performed. Teflon patch graft for closure of V.S.D. through tricuspid orifice and pulmonary Valvulotomy through pulmonary arteriotomy were performed. The post-op low cardiac output Syndrome and dysrhythmia were developed till postoperative day #7, so that was controlled by inotropic and antiarrhythmic agents. After that, patient`s conditions were Uneventful. [KTCS 1982;3:346-354]
