Abstract:
Objective To observe the efficacy of hybrid balloon valvuloplasty for the treatment of low-body weight infants with severe congenital valvular aortic stenosis ( AS ).Methods Five infants with severe congenital valvular aortic stenosis underwent the hybrid balloon aortic valvuloplasty through median sternotomy in the hybrid operating room.The mean age was (40.2 ± 7.0) days,weight was (4.48 ± 0.75 )kg.The patients were followed up by echocardiography for 9 - 13 months post procedure.Results Operation was successful in all 5 patients and they were discharged from hospital uneventfully.The gradient pressure decreased significantly from (98.8 ±9.0)mm Hg( 1 mm Hg =0.133 kPa) to ( 13.8 ±3.3) mm Hg (P ＜0.05)post operation. There was no moderate or severe aortic insufficiency. All patients were alive,the gradient pressures was ( 18.8 ± 2.5) mm Hg and there was no moderate or severe aortic insufficiency during follow-up [ 9 - 13 (11.0 ± 1.4) months ].Conclusion The hybrid balloon aortic valvnloplasty is an effective option for the low-body weight infants with severe congenital valvular aortic stenosis.
