ABSTRACT
BACKGROUND:
We hypothesized that primary sutureless (SL) repair of total anomalous pulmonary venous drainage (TAPVD) may have a lower incidence of postrepair pulmonary vein obstruction (PVO) and different modes of PVO compared with standard repair (SR).METHODS:
One hundred ninety-five patients who underwent TAPVD repair (1990 to 2012) with the exception of congenital pulmonary vein stenosis, isomerism, and single-ventricle anomalies were included. Survival, reintervention, incidence, degree of PVO were compared between groups. The mode of PVO was expressed as central or peripheral. The Mann-Whitney test, Kaplan-Meier analysis, and Cox regression were used.RESULTS:
The SL group had more infracardiac or mixed TAPVD (p = 0.02) and preoperative PVO (p = 0.07). There were no differences between SR and SL groups in survival (5-year survival, 83.1% versus 82.5%, respectively; p = 0.73) and composite outcome (death, intervention, PVO, 5-year survival, 76.4% versus 80.7%, respectively; p = 0.225). The SL group had a lower incidence of PVO of moderate or greater degree (SR, 11.3% versus SL, 2.9%; p = 0.05) than the SR group, especially in the infracardiac and mixed TAPVD cohort (p = 0.011), with a lower pulmonary vein score (SR, 8 versus SL, 4; p = 0.01). The SL group had peripheral PVO exclusively (100%), whereas the SR group predominantly had central PVO (76.4%; p = 0.005). There was a trend toward less reoperation in the SL group (SR, 10.4% versus SL, 2.9%; p = 0.08). Survival after reoperation was comparable to primary TAPVD repair types as well as reoperation repair types.CONCLUSIONS:
Primary SL appeared to be associated with a lower incidence and severity of PVO. The primary SL repair eliminated the risk of developing central PVO, although a relatively benign type of peripheral PVO could occur.
