Inclusion criteria

Inclusion criteria: Patients who underwent non-contrast chest CT at our institution prior to arrhythmia ablation. DICOM data required for analysis are available in the PACS and are suitable for transfer to the workstation for analysis.

Exclusion criteria

Exclusion criteria: Missing or corrupted image data required for analysis. Images with severe motion or respiratory artifacts that preclude assessment of the predefined anatomical landmark regions. Cases in which anatomical identification of the evaluation region is difficult due to prior surgery or marked anatomical distortion.
