Meandering left pulmonary vein with right partial anomalous pulmonary venous connection and sinus venosus atrial septal defect in a child

Q: What is the clinical evidence from this study?

Study design: Case Report. Population: Meandering left pulmonary vein with right partial anomalous pulmonary venous connection (PAPVC) and sinus venosus atrial septal defect (ASD) (n=1). Intervention: Computed tomography angiography (CTA). Primary outcome: Delineation of pulmonary venous anatomy and associated cardiovascular anomalies.

Key result

CTA detects a meandering left pulmonary vein alongside right PAPVC and sinus venosus ASD.

Key Points

Describe the rare coexistence of a meandering left pulmonary vein with contralateral right partial anomalous pulmonary venous connection and a sinus venosus atrial septal defect in a pediatric patient.
Evaluated a 3-year-old boy presenting with shortness of breath and recurrent pneumonia using transthoracic echocardiography followed by computed tomography angiography (CTA).
Performed dual-source CTA under light sedation with an ECG-gated adaptive protocol (80 kVp, 1.1 mSv effective radiation dose, 1 mL/kg nonionic contrast) to map pulmonary vascular anatomy.
Echocardiography identified a right superior pulmonary vein draining into the superior vena cava, a sinus venosus atrial septal defect, and mild right atrial and ventricular enlargement.
CTA revealed a 7-mm-diameter left superior pulmonary vein following a tortuous course through the left upper and lower lobes before joining the left inferior pulmonary vein to drain normally into the left atrium.
CTA excluded mirror-image scimitar variant, sequestration, and arteriovenous malformations, demonstrating that the meandering vein required no surgical intervention.

Population

A 3-year-old boy presenting with shortness of breath and recurrent pneumonia, found to have a right partial anomalous pulmonary venous connection, sinus venosus atrial septal defect, and a meandering left superior pulmonary vein.

I

Intervention

Computed tomography angiography (CTA) using a 192-detector dual-source CT scanner with an ECG-gated adaptive protocol and non-gated FLASH scan (80 kVp, 1.1 mSv effective dose) with 1 mL/kg nonionic contrast under light sedation.

Outcome

Anatomical diagnosis and delineation of pulmonary venous drainage and associated congenital cardiac anomaliessurrogate

Computed tomography angiography is critical for accurately characterizing rare meandering pulmonary veins missed on echocardiography and preventing them from being mistaken preoperatively for anomalous connections requiring surgical intervention.

Implication

CTA distinguishes benign meandering pulmonary veins from anomalous connections in congenital heart disease; leaves open standardized imaging protocols for similar pediatric cases.

Johnson et al. (2026) conducted a case report in Meandering left pulmonary vein with right partial anomalous pulmonary venous connection (PAPVC) and sinus venosus atrial septal defect (ASD) (n=1). Computed tomography angiography (CTA) was evaluated on Delineation of pulmonary venous anatomy and associated cardiovascular anomalies. Computed tomography angiography identified an incidental 7-mm meandering left superior pulmonary vein draining normally into the left atrium alongside a right PAPVC and sinus venosus ASD.
