Pneumomediastinum Causing Distortion on Transesophageal Echocardiography as a Result of Tracheal Injury After Sternotomy

Abstract

Fig 2. Echocardiogram of the mitral valve recorded simultaneously with the electrocardiogram and phonocardiogram during held respiration. A dense band of echoes that begins with a prominently recorded click (C) was noted to obscure the normal structures. Posteriorly, a gap (G) occurred as a result of a total drop-off of the echocardiographic image. S1, first heart sound; S2, second heart sound. Used with permission from Reid et al. 4
