3.1 | Patient Characteristics
From March 2008 to August 2018, 97 patients were diagnosed as FSV with
TAPVC at our center. Fifty-four patients who did not receive surgery for
various reasons were excluded. Finally, forty-three patients were
included in our retrospective study (Figure 1). The body weight and
median age were 12 (range 5-44) kg and 32 (range 2-256) months,
respectively. Among these cases, there are 19 cases of supracardiac
TAPVC, 22 of intracardiac type, and 2 of mixed type. Right atrial
isomerism was diagnosed in 34 patients (79%), and preoperative
pulmonary vein obstruction, that was defined by transthoracic
echocardiography as a flow rate more than 1.2 m/s, in 6 (13.9%).
According to whether TAPVC had been repaired, patients were divided into
TAPVC repair group and non-TAPVC repair group (Table 1). Type of TAPVC
(p < 0.001), preoperative pulmonary vein obstruction
(p = 0.001), and totally mortality (p = 0.002 ) were
significant difference between these two groups.
