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.
