Predischarge echocardiography service for postnatal heart murmurs provided by neonatologists has the benefit of providing an early diagnosis, counselling of the parents and arranging appropriate follow-up. It helps to triage the referrals to the cardiologist. We felt that we were able to alleviate parental anxieties by providing a definitive diagnosis and written information prior to discharge from hospital. We strongly believe that this service should only be provided by those appropriately trained and skilled in echocardiography.

We report two cases of transcatheter-device closure of aortopulmonary windows, a residual defect occurring after previous surgical closure, and a native lesion. The postsurgical defect was closed with an Amplatzer Duct Occluder II (AGA Medical Corporation, MN). The native lesion was not suitable for an Amplatzer Duct Occluder II device; thus, it was closed using an Amplatzer Duct Occluder (AGA Medical Corporation, MN). The Amplatzer Duct Occluder II provides an additional device for aortopulmonary window closure, but anatomy and defect characteristics dictate the most appropriate device.

Pulmonary agenesis is a rare congenital anomaly, estimated to complicate around 1 per 15,000 pregnancies, in which there is complete absence or severe hypoplasia of one or both lungs, frequently associated with other abnormalities. A prospective prenatal diagnosis is a challenge, and a substantial proportion of cases are diagnosed by fetal magnetic resonance imaging, postnatal computed tomography, or postmortem. Thus, there are only a few reported cases of prenatal diagnosis in the literature. We report the prenatal diagnosis of isolated right lung agenesis diagnosed with sonography alone at a relatively early gestational age. We also present a systematic review of the literature for this condition to accompany this case study.
