[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. The systolic pulmonary artery pressure was estimated at 80 mmHg. The patient was treated by surgical excision of the intra-left atrial membrane.

[Subtotal cor triatrium with left partial anomalous pulmonary venous connection--successful correction in an infant].

This report concerns a 10-month-old infant with subtotal cor triatrium associated with left sided partial anomalous pulmonary venous connection to the innominate vein. In the operation, we found that the fossa ovalis existed between the right atrium and the accessory atrial chamber. We performed a radical operation which consisted of a resection of the intra-left-atrial diaphragma and a anastomosis of the vertical vein to the left atrium. His postoperative course was uneventful, and the result was satisfactory. We have presented and reviewed our case, and then discussed the embryogenesis and the hemodynamics. To our knowledge, our case represents the first successful surgical repair of this combination of defects in Japan.

[Left intra-atrial membrane without pulmonary vein obstruction: benign condition of progressive evolution? Apropos of 7 cases].

Left triatrial heart is defined as division of the left atrium into two chambers, proximal and distal, by a variably perforated membrane. The data of appearance of symptoms, often in early childhood, is related to the degree of obstruction and the presence or not of an inter-atrial shunt. Widescale usage of echocardiography, the investigation of choice for this diagnosis, has led to the detection of this abnormality in older patients, sometimes asymptomatic, without pulmonary hypertension. Three adults were referred for transthoracic and transoesophageal echocardiography to investigate systemic embolic disease (2 cerebral, 1 mesenteric). Two other adults underwent the same investigations for diagnosis of the aetiology of atrial fibrillation with mitral regurgitation. Two cases were asymptomatic children, one with a clinically benign murmur and the other with ventricular extrasystoles with no malignant features. In these seven cases, transthoracic (n = 5) and/or transoesophageal (n = 7) echocardiography demonstrated a left atrial membrane corresponding to the classical description of cor triatrium. The Doppler study showed no obstruction in 6 cases and minimal obstruction in 1 case. In our series, as in similar cases reported in the literature, the diagnosis of a left atrial membrane did not lead to surgery. Although we do not know the long-term outcome of this abnormality in asymptomatic children, the observations of complications in the adult suggest a potential of evolution which poses the question of optimal management.
