“…Samples representing extreme values of cardiothoracic ratio and cardiac diameter were compared; patients with cardiothoracic ratio near the maximum limit, which is considered normal in the literature 12,13 , were not assessed. In addition, the authors 14 considered a cardiothoracic ratio of 0.5 as abnormal, contrary to the maximum limit value adopted for the cardiothoracic ratio in our study 12,13 .…”

“…Although cardiac size may be determined by chest radiography, many cardiac and extracardiac factors influence this measure, such as the examination technique, the patient's biotype, the patient's physiological status, thoracic alterations (scoliosis, pectus excavatum), the size of the lungs, the breathing phase, the cardiac cycle phase, and heart rate at the time of examination 12,13 . Therefore, chest radiography may only provide a raw and sub- Data in percentages, except # mean ± SD, and * median (minimum and maximum).…”

“…The area below the curve varies from zero to 1 and measures the accuracy of a diagnostic test. Considering 0.5 as the cut point established in the literature 12,13 , the sensitivity, specificity, and positive and negative predictive values of the cardiothoracic ratio on the diagnosis of left ventricular dysfunction were calculated.…”

Figure 1. Parasternal imaging in diastole. A. Long-axis image-a prosthetic valvular color jet directed toward the interventricular septum (arrow). (LA = left atrium; LV = left ventricle). B. Short-axis image-the diastolic jet appears to be "central valvular" and "linear" in shape (arrow). (RVOT = right ventricular outflow tract).A 76-year-old retired physician underwent routine follow-up echocardiography for a 29-mm CarboMedics bileaflet mechanical prosthesis (Sorin Biomedica Cardio, Arvada, CO, USA) placed 8 years earlier, for aortic stenosis. A new "linear central" prosthetic aortic regurgitant jet, directed toward the left ventricular septum, was noted by transthoracic echocardiography (TTE) (Fig. 1, movie clips S1 and S2), compared to a TTE 3 years earlier.
