Abstract The development and timing of aortic valve prolapse (AoVP) and aortic regurgitation (AR) was studied by two-dimensional echocardiography in 99 consecutive patients with supracristal ventricular septal defect (VSD). Thirty patients (30%) had aortic valve prolapse (VSD + AoVP group), and 31 patients (31%) had AoVP with AR (VSD + AoVP + AR group). In the VSD + AoVP group, AoVP was detected first by echocardiography at the age of 6.8 ± 4.2 years (mean ± SD). In the VSD + AoVP + AR group, the interval from detection of AoVP to the appearance of AR was 3.4 ± 2.0 years. The configuration of the prolapsed aortic valve was echocardiographically classified into two types: tear-drop type (small) prolapse and box type (large) prolapse. The frequency of tear-drop type prolapse was not significantly different between VSD + AoVP and VSD + AoVP + AR groups (43% versus 32%, respectively), indicating that even minor AoVP can result in AR. Four infants (4%) had AoVP at the ages of 1, 5, 7, and 11 months, respectively. All infants had tear-drop type prolapse. Two infants developed AR by colour flow mapping at the ages of 3 and 11 months, and the interval from prolapse to AR was only 2 and 4 months, respectively. Conclusion Aortic valce involement can develop under the age of 1 year in supracristal VSD. Regular evaluation by two-dimensional echocardiography with colour flow mapping is important in the follow-up of children with supracristal VSD.
