Abstract:
A thirteen-day-old neonate was admitted because of systolic heart murmur, tachycardia, tachypnea and sucking weakness. The chest X-ray film demonstrated remarkable cardiomegaly and pulmonary congestion. Echocardiography detected marked thickening and stenosis of the aortic valve, and left ventricular dysfunction (EF=10%). The pressure gradient between left ventricle and ascending aorta was presumed 130mmHg with pulsed Doppler echocardiography, Since he did not respond to conservative treatment, an emergency open aortic valvular commissurotomy under cardiopulmonary bypass was performed the day after admission. We made incisions of 1mm in the left side and 0.5mm in the right side commissure of the adherent bicuspid aortic valve. After the procedure, left ventricular function improved (EF=57%), and the pressure gradient was reduced to 62mmHg. He showed good recover from the congestive heart failure. There are few reports about operative treatment of congenital aortic valve stenosis in neonates. This is considered to be the third youngest successful operative case of open aortic valvular commissurotomy in Japan.
