Efficacy of hybrid balloon valvuloplasty via sternotomy for treating low-body weight infants with severe congenital valvular aortic stenosis / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe the efficacy of hybrid balloon valvuloplasty for the treatment of low-body weight infants with severe congenital valvular aortic stenosis (AS).</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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].</p><p><b>CONCLUSION</b>The hybrid balloon aortic valvuloplasty is an effective option for the low-body weight infants with severe congenital valvular aortic stenosis.</p>
