[[Doppler echocardiography in the diagnosis of tri-atrial heart in adults].
The authors report a case of isolated and well tolerated cor triatriatum in a 38-year old man without significant history admitted for aetiological diagnosis of atrial fibrillation. Echocardiography displayed the left intra-atrial septum and the openings of the 4 pulmonary veins in the proximal chamber, but there was no evidence of associated anomaly. Colour-coded doppler examination visualized a single systolo-diastolic trans-septal jet. As the maximum velocity of the jet at pulsed doppler velocimetry was 1.1 m/s, the maximum instantaneous gradient could be estimated at 5 mmHg. The mean gradient was estimated at 2.6 mmHg, which showed that the ostium caused little stenosis. All these data were confirmed by cardiac catheterization. Since the malformation was well tolerated, both functionally and haemodynamically, it was decided not to operate.
