Imaging of Acquired Pulmonary Venous Disease

Area of Science:

• Radiology
• Cardiovascular Imaging
• Pulmonary Medicine

Background:

• Acquired pulmonary venous diseases are often detected incidentally or post-atrial fibrillation ablation.
• Subtle findings in the pulmonary veins can be challenging to identify, especially on non-gated imaging.
• High index of suspicion is crucial for diagnosing these often-overlooked conditions.

Purpose of the Study:

• To review key acquired pulmonary venous abnormalities.
• To outline pathophysiology, imaging features, and clinical implications.
• To highlight imaging challenges and avoid misdiagnosis.

Main Methods:

• Review of literature on acquired pulmonary venous abnormalities.
• Focus on imaging features and diagnostic challenges.
• Discussion of pathophysiology and clinical significance.

Main Results:

• Key abnormalities include pulmonary vein stenosis, thrombosis, tumor invasion, and meandering pulmonary veins.
• Cardiac-gated CT and MRI are primary imaging modalities.
• Echocardiography and catheterization may aid diagnosis in specific cases.

Conclusions:

• Accurate diagnosis of acquired pulmonary venous disease requires recognizing subtle imaging findings.
• Understanding pathophysiology and potential imaging challenges is vital for appropriate management.
• This review aims to improve diagnostic accuracy and clinical decision-making.
