The long-term consequences of the coronary artery lesions in pulmonary atresia with intact ventricular septum

The outcome for all children born in Sweden between January 1, 1980 and December 31, 2008 with ventriculo-coronary arterial communications (VCACs) and pulmonary atresia with intact ventricular septum (PAIVS) was assessed. Fifty-one subjects, 42%, of all 125 children born with PAIVS had identifiable VCACs. Cumulative survival after surgery was 67%, as compared with 73% for all subjects born with PAIVS (n.s.). Survival improved over time, and there was no late death after 3years of age. Median follow-up time was 12years (range 1–28years). At follow-up, 33 subjects were alive (12 female/21 male) with the following repairs: six had a biventricular repair, one had 1.5 ventricle repair, 25 were palliated with a single ventricle repair (final stage in 20), and one had a heart transplantation. Notably after decompression (n=9 survivors), the disease in the coronary arteries did not progress, although four subjects in this group had large VCACs. In the group of subjects with single ventricle repair and large VCACs, eleven were found to have stenoses in the coronary arteries. The disease in the coronary arteries in this group, however, often progressed with an adverse effect on myocardial perfusion. Four of the survivors had documented myocardial infarctions.
