Experience on transplantation of auto-pulmonary graft treating with congenital aortic disease / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To summarize the experience on auto-pulmonary transplantation (Ross procedure) treating with congenital aortic disease.</p><p><b>METHODS</b>From October 1994 to November 2003, 20 cases of Ross procedure were performed to treat with congenital aortic disease, Male 15 cases; Female 5 cases; age 25 years;</p><p><b>DIAGNOSIS</b>congenital heart disease (CHD), aortic abnormalities 12 cases; aortic valve prolapse 5 cases; aortic valve hypogenesis 3 cases; combined with subacute bacterial endocarditis (SBE) 4 cases, and ventricle septal defect (VSD) 2 cases; UCG showed aortic stenosis(AS) and/or aortic insufficience (AI) (moderate to severe), Left ventricle diastole diameter (LVDD) (60.51 +/- 11.87) mm, the grade pressure across aortic valve (27.04 +/- 6.80) mmHg, heart function (NYHA) Class II 13 cases; Class III 3 cases; all cases were performed under CPB and moderate hypothermia, the operation procedure was following (1) taking off auto-pulmonary artery valve; (2) removing dysfunctional aortic valve and auto-transplantation of pulmonary valve on aortic root; (3) putting a pulmonary homograft to rebuild right ventricular outflow tract.</p><p><b>RESULTS</b>The mortality was 0 during stay at hospital, aortic valve function were all normal, LVDD decreased significantly (t = 3.4007, P = 0.0008), the grade pressure across aortic valve was in normal limitation, (6.8 +/- 0.19) mmHg. Follow-up showed heart function was in Class I (NYHA), aortic and pulmonary valve function was very well.</p><p><b>CONCLUSION</b>Ross procedure is a kind of effective alterative operation for treating with congenital aortic valve disease, with good short and middle term results.</p>
