Double outlet right ventricle (DORV) and transposition of the great arteries (TGA) with ventricular septal defect (VSD) and pulmonary stenosis (PS) are complex heart diseases, the treatment of which remains a surgical challenge. The Rastelli procedure is still the most commonly performed treatment. Aortic root translocation including an arterial switch operation is advantageous anatomically since it has a lower possibility of conduit blockage and the left ventricle outflow tract remains straight. This study reports successful aortic root transpositions in two patients, one with DORV with VSD and PS and one with TGA with VSD and PS. Both patients were discharged without postoperative complications.

Whatever a surgeon choose aortic prosthesis in aortic stenosis, it will always provoke some degree of obstruction to flow due to its smaller effective orifice area to tissue annulus. Occasionally, we meet small aortic annulus to his or her body surface area in aortic valve replacement. The small annulus remains a problem in that both tissue and mechanical prosthesis have significant pressure gradients between LV and aorta in resting or exercising states. In these circumstances, diverse surgical procedures, such as tilting disc prosthesis, supraannular position of aortic prosthesis, and enlargement of aortic root [including aortoventriculoplasty, translocation of aortic valve, & double outlet of LV by valved conduit], were applied. We experienced one case of aortic stenosis with small aortic annulus. Systolic pressure gradients between LV & aorta were 90 mmHg. Diameter of annulus was 19 mm. So we performed patch enlargement of aortic root by Manouguian and AVR with St. Jude medical valve 23 mm.
