ObjectiveTo analyze the results of surgical treatment of severe aortic stenosis in infants.MethodsFrom August 2012 to December 2019, 28 infants undergoing aortic valvuloplasty in our hospital were selected, including 22 males and 6 females, aged 62.00 (47.00, 82.50) d. The baseline characteristics of the patients, postoperative complications and follow-up results were analyzed.ResultsTwenty (71.43%) patients had bicuspid aortic valves. Five (17.86%) patients had heart failure and two (7.14%) patients used prostaglandin before surgeries. Postoperative mechanical ventilation time was 25.00 (17.00, 62.75) h, ICU stay was 3.50 (2.00, 8.50) d and postoperative hospital stay was 10.00 (7.00, 16.50) d. Four (14.29%) patients got delayed recovery (ICU stay>14 d). One (3.57%) perioperative death was observed. The follow-up time was 55.00 (43.25, 82.25) months. No death was found during follow-up. Four (14.81%) patients underwent a second operation, including three (11.11%) patients with severe aortic stenosis, and one (3.70%) patient with severe regurgitation.ConclusionInfants with severe aortic stenosis are seriously ill and have a long postoperative recovery time, requiring early surgery. The postoperative follow-up results are satisfactory.
