RESUMO
We report an unusual variant of obstructed supra cardiac anomalous pulmonary venous drainage where the vertical vein is obstructed by a vice formed between the persistent arterial duct and the left pulmonary artery.
RESUMO
BACKGROUND: Previous studies have demonstrated increased early mortality and pulmonary vein reintervention for patients with total anomalous pulmonary venous connection (TAPVC) and heterotaxy syndrome (HTX+) compared with patients with TAPVC without heterotaxy syndrome (HTX-). We aimed to evaluate the longitudinal risk of pulmonary vein reintervention and mortality in HTX + patients. METHODS: A retrospective review was performed to identify longitudinal interventions in patients with TAPVC seen at a single center from 1995 to 2019. The mean cumulative interventions were described for all patients using the Nelson-Aalen estimator. Survival with TAPVC was described using Kaplan-Meier estimates. RESULTS: A total of 336 patients were identified with TAPVC, of whom 118 (35%) had heterotaxy syndrome. Functional single ventricles were identified in 106 of these 118 HTX + patients (90%) and in 14 of 218 HTX- patients (6%) (P < .001). Obstructed TAPVC (OBS+) was present in 49 of 118 HTX + patients (42%) and in 87 of 218 HTX- patients (40%) (P = .89). The median duration of follow-up was 6.5 years. Five-year survival was 69% for HTX+/OBS + patients, 72% for HTX+/OBS- patients, 86% for HTX-/OBS + patients, and 95% for HTX-/OBS- patients (P < .0001, log-rank test). The mean number of pulmonary vein interventions at the median follow-up time was greater in the HTX+/OBS + patients compared with HTX+/OBS- patients (mean, 2.0 vs 1.1; P = .030), HTX-/OBS + patients (mean, 1.3; P = .033), and HTX-/OBS- patients (mean, 1.3; P = .029). CONCLUSIONS: Among the 4 cohorts, HTX+ was associated with a higher rate of mortality, and HTX+/OBS+ was associated with a greater number of pulmonary vein interventions. This may be due in part to the high prevalence of single ventricle physiology in the HTX + cohort.

This article combines material from three complementary overviews presented in the Symposium on Pulmonary Venous Anomalies during the Joint Meeting of the World Society for Pediatric and Congenital Heart Surgery and Sociedad Latina de Cardiologia y Cirugia Cardiovascular Pediátrica in Lima, Peru. We discuss the embryologic basis for nomenclature, the hierarchical diagnostic categories, and the important anatomic and morphologic characteristics of anomalous pulmonary venous connections. The anatomic descriptions help to guide an understandable and sensible approach to the diagnosis and surgical management of these various disorders.
