[False aneurysm complicating ligation of patent ductus arteriosus operated on successfully].

Postoperative aneurysm of ductus arteriosus is a rare complication but may be lethal without treatment. It is less frequent than spontaneous aneurysm of ductus arteriosus. We report the case of 5 years-old girl who underwent a ligation of patent ductus arteriosus complicated, 6 months later, with a false aneurysm of ductus arteriosus and endocarditis of the ductus and the aortic valve.

[Obstructive left triatrial heart in the adult. Echocardiographic appearances].

The authors report the case of a 23-year old man who presented with signs of pulmonary hypertension due to an obstructive left triatrial heart in adulthood. Transthoracic and transoesophageal echocardiography showed a partially calcified intra-left atrial membrane perforated in its centre. Doppler analysis of flow through the membrane showed continuous systolo-diastolic flow at high velocity indicating haemodynamic obstruction.
