We sought to evaluate the value of echocardiography in the diagnosis of different types of anomalous pulmonary venous connections (APVC) and summarize the diagnostic experience.
Eight-four patients with APVC underwent surgical correction or computerized tomography angiography in the last 6 years (2008-2014) at the Wuhan Union Hospital.
The total anomalous pulmonary venous connection (TAPVC) cases account for 60.7% and partial anomalous pulmonary venous connection (PAPVC) cases account for 39.3% among the 84 cases that were identified. The 51 TAPVCs were classified by the Darling method: type I (41.1%), type II (52.9%), type III (1.9%), and type IV (3.9%). The most common drainage path of type I was common pulmonary drainage to the left innominate vein via vertical vein and the coronary sinus drainage was the most common path in type II. Compared with surgical results, the sensitivity and specificity of echocardiography in the diagnosis of APVCs were97.6% and 99.9%. The echocardiography misdiagnoses were mainly seen in PAPVCs. Of the 50 cases of TAPVCs, the diagnostic accuracy of classification was 94%.
Echocardiography has specific value in diagnosing and classification of APVC, especially the supracardiac and cardiac TAPVCs. Multiplane scan views and Color Doppler improving the display of drainage pathway.
