Chest X – Ray : Heart Failure Dr.Juan A.Venter Dept.Imaging Sciences Universitas Hospital
Causes:PVH/Pulmonary Oedema Left Ventricular Failiure Left Ventricular Outflow Obstruction Mitral Valve Disease Left Atrial Myxoma Fibrosing Mediastinitis Pulmonary Venous Occlusive Disease
Non Cardiogenic Pulmonary Oedema – Normal Cardiothoracic Index Aspiration ,Near Drowning ARDS Hepatorenal Failiure Post thoracocenthesis – Rapid Lung Expansion Drugs : Aspirin,Nutrofurantoin,Opiates,Cytokines PS:Early post MI phase – acute decrease in miocardial compliance
Right Atrial Enlargement PA CXR: Prominent round superior border with SVC > 5,5 cm from midline to most lateral RA margin > 2,5 cm from right vertebral margin
Right Ventricular enlargement PA CXR: Upturned cadiac apex Lateral CXR: > 1/3 contact distance from cadiophrenic sulcus to sternal angle
Left Atrial Enlargement PA CXR: Retrocardiac double density >75 % splaying of carina with horizontal orientation of left mainstem bronchus Enlarged left convex left atrial appendage > 7 cm from LMB to right LA border. Lateral CXR: Posterior displacement of Ba filled oesophagus
Left Ventricle Enlargement PA CXR: Downturned cardiac apex with leftward displacement Left diaphragmatic inversion Lateral CXR: Posterior cardiac margin > 1,8 cm posterior to IVC meassured 2 cm above intersection of right hemidiaphragm with IVC.(Hofman-Rigler rule)
