Left anterior accessory pathways are considered to be rare findings. Catheter ablation of accessory pathways in this location remains a challenging target, and few reports about successful ablation of these accessory pathways are available. We describe our experience regarding a case of a manifest left anterior accessory pathway ablation using radiofrequency energy at the junction of the left coronary cusp with the non-coronary cusp.

Quadricuspid aortic valves are rare congenital anomalies, usually diagnosed in adult patients affected by severe aortic regurgitation. We have now encountered three such valves in children undergoing transthoracic echocardiography. All children were asymptomatic. The first child possessed a valve with two larger leaflets, and smaller leaflets of equal size. In the second child, 3 leaflets were of equal size, with 1 small accessory leaflet. The third child had a valve with four leaflets of approximately equal size. In one child, the aortic valve was functioning normally, and came to attention because of mitral valvar prolapse causing mild regurgitation. In the remaining two children, central mild aortic regurgitation was detected using colour flow analysis, and associated dilation of the aortic root was revealed by measurements of the cross-sectional images.

Aorto-left ventricular tunnels are anomalous communications between the ascending aorta and the left ventricle. Prenatal diagnosis, followed by successful surgical management, is rare. We describe a fetus diagnosed with aorto-left ventricular tunnel at 35 weeks who achieved a favourable outcome after immediate postnatal surgical repair.
