  Figure 1. Case 1: Pre- and Post-Intervention Venogram (A) Preintervention angiographic image showing left superior and left inferior pulmonary veins (confluent in common vein) severe stenosis. The green arrow is pointing toward the narrowing in the common left pulmonary vein. The red arrow is pointing toward the narrowing in the left superior pulmonary vein. (B) Postintervention angiographic image showing restoration of flow in the left pulmonary veins. The green arrow demonstrates resolution of stenosis in the left common pulmonary vein. The red arrow demonstrates resolution of stenosis in the left superior pulmonary vein.

  Figure 2. Case 2: Pre- and Post-Intervention Venogram (A) Preintervention angiographic image highlighting left inferior pulmonary vein stenosis. The red arrow is pointing to the stenotic segment in the left inferior pulmonary vein. (B) Postintervention image showing flow restoration with good angiographic results. The red arrow demonstrates resolution of stenosis in the left inferior pulmonary vein.

  Figure 3. Case 3: Pre- and Post-Intervention Venogram (A) Preintervention angiographic image showing occlusion of the left superior pulmonary vein. The red arrow is pointing to the occluded left superior pulmonary vein. (B) Postintervention image showing flow restoration with good angiographic results. The red arrow is pointing toward the recanalized left superior pulmonary vein.

  Figure 4. Case 4: Pre- and Post-Intervention Venogram (A) Preintervention angiographic image showing occlusion of the left superior pulmonary vein. The red arrow is pointing to the occluded segment of the LSPV. (B) Postintervention image showing flow restoration with good angiographic results. The red arrow is pointing toward the recanalized left superior pulmonary vein.
