Results of Senning operation for transposition of great arteries.
We report our results with 10 infants and children who underwent atrial repair using the Senning operation between 1985 and 1990. All cases had abdominal situs solitus, levocardia and atrio-ventricular concordance (D-bulboventricular loop). Nine patients had simple D-transposition of the great arteries without ventricular septal defects (VSD) or left ventricular outflow tract obstruction. The other patient had a double outlet right ventricle with subpulmonic VSD and pulmonary hypertension (PHT) and underwent a palliative Senning procedure. All patients had a balloon atrial septostomy (BAS) before surgery, except for one with Taussig-Bing syndrome. One patient had a Blalock-Hanlon operation after BAS. The age at the time of surgery ranged from two months to four years seven months (mean: 22 months) and weight ranged from 4.3-12 kg. There were two hospital mortalities including the patient with VSD and PHT. All of the patients had echocardiographic examinations and six of the eight survivors received cardiac recatheterization four to 19 months (mean: 7.4 months) postoperatively. No baffle leaks were noted in the survivors. Two patients had both mild tricuspid regurgitation and slightly decreased right ventricular contractility, and one patient had a pressure gradient of 6 mmHg between the superior vena cava and neo-right atrium. The clinical follow-up interval was eight to 64 months (mean: 31.4 months). All survivors showed a sinus rhythm on their latest electrocardiogram and were participating in normal daily activities without medication.
