[Total anomalous pulmonary venous drainage: is a surgical correction possible on the sole basis of echocardiography?].
Between April '83 and August '89, 33 patients with total anomalous pulmonary venous drainage were studied at the department of Cardiology in Bergamo. There were 18 males and 15 females, aged between three days and 8 months (average: two months). In this study only cases of isolated total anomalous pulmonary venous drainage were taken into consideration. The patients underwent echocardiographic examination with ATL MK 600, Vingmed 700, ATL Ultramark 9 with 3.5; 5; 7.5; MHz transducers; in the last three years the echocardiographic examination was integrated by continuous and pulsed wave Doppler and, in the last year, by color Doppler. The morphologic diagnosis was routinely established by means of the sequential approach method. A common feature in all types of total anomalous pulmonary venous drainage was the impossibility of defining the connections of the pulmonary veins with the left atrium. Furthermore, patients had a volume overload of the right heart, and atrial septal defects of various sizes. The site of anomalous drainage of the pulmonary veins was assessed by means of multiple cuts from subcostal, precordial and suprasternal windows. The echocardiographic diagnosis was exact and complete in 29 cases (87.9%), and in four cases it was incomplete but basically correct (12.1%). The anatomical findings were confirmed during cardiac surgery in 32 cases and by autopsy in one case of supracardiac total anomalous pulmonary venous drainage in a critically ill patient, who died before surgery. Of the 32 patients who underwent surgical correction, 20 (62.5%) had only an echocardiographic diagnosis, which resulted correct in all cases. The majority of patients with isolated TAPVD can be confidently diagnosed by means of echocardiography, thus, avoiding preoperative catheterization.
