Tuberculous-destroyed lung: cardiovascular CT findings and prognostic imaging factors

The purpose of this study was to evaluate cardiovascular computed tomography (CT) findings in tuberculous-destroyed lung (TDL) and to correlate these imaging features with survival. CT was assessed for the diameter of the pulmonary artery (dPA) and ascending aorta, the diameters of ventricles, ventricular septal bowing (VSB), extent of TDL, or hypertrophied bronchial artery and others. Seventy-three percent of the TDL patients had a dPA greater than 29 mm. The right ventricle (RV)/left ventricle (LV) ratio in 70% of the patients was greater than 1.0, and VSB was observed in 18%. The RV/LV ratio was the only independent risk factor for poor survival in statistical analysis.
