A young Coloured man whose only symptom was that of minimal dyspnoea on exertion, on examination had signs of infundibular stenosis which were confirmed by cardiac catheterization. Additional features were left anterior hemiblock and cardiomegaly as delineated radiologically. Cross-sectional echocardiography revealed a very large cystic mass located within the interventricular outflow tract. This cystic mass was further delineated by cardiac cine angiography. It is postulated that this mass was a primary cardiac echinococcal cyst and was directly responsible for the complications of left anterior hemiblock and the infundibular obstruction. The patient declined surgery and a definitive pathological diagnosis could therefore not be made. If this is a hydatid cyst then it is the second case reported in the literature diagnosed by two-dimensional echocardiography and in which left anterior hemiblock has been recorded. The clinical features, complications and surgical correction are briefly outlined.
