Background: In this study, we present early and mid-term outcomes of Ross and Ross-Konno operation in pediatric patients with congenital aortic stenosis.

Methods: Between January 2011 and December 2015, a total of eight patients (4 boys, and 4 girls; median age 4.5 years; range 3 to 17 years) with a preliminary diagnosis of congenital aortic stenosis underwent either Ross or Ross-Konno operation were retrospectively analyzed. Duration of cardiopulmonary bypass and cross-clamp, and length of intensive care unit and hospital stays were recorded.

Results: Seven patients had previous interventions [balloon valvuloplasty (n=4), ventricular septal defect repair (n=1), aortic valve repair (n=1), and aortic coarctation repair (n=1)]. The Ross-Konno operation was performed in five patients, while the remaining three patients underwent the Ross operation. Additional subaortic resection was required in two patients and mitral valve repair in one patient. Only one adult-sized patient had pulmonary autograft wrapping with Dacron conduit. There was no mortality and major morbidity. The mean cardiopulmonary bypass and cross-clamp times were 234±6 and 177±4 min, respectively. Two patients underwent delayed sternal closure. The median length of intensive care unit and hospital stays was 4.5 and 13.5 days, respectively. The mean follow-up was 29.3±15.6 months (range, 3 months to 4 years). Only two patients had mild-to-moderate pulmonary conduit stenosis. There was no moderate or severe aortic valve regurgitation in the final follow-up visit.

Conclusion: Our study results show very good pulmonary autograft and pulmonary conduit functions in the mid-term follow-up. Based on these findings, the Ross and Ross-Konno operations remain a good option for aortic valve replacement in infants and children with low mortality rates.
