Logic would suggest any two structures in close proximity can have some sort of anatomical , physiological or sometimes pathological relationship .Esophagus and heart share a strategic anatomical space within the mediastinum . The left atrial wall is abetting the esophagus with only few millimeters separating the two. Trans esophageal echocardiography has utilised this proximity for it’s advantage . With the probe in esophagus we can get a 100% interior view of left atrium . Both these structures can mutually compress one another at times of pathology . ( LA compression on esophagus in mitral stenosis , Esophageal compression of LA in hiatus hernia or esophageal growths) . Now , we also realise , esophagus a functionally unrelated structure to cardiovascular system can have a impact on cardiac functioning.
Hiatus hernia of gastroesophageal junction can mechanically compress the posterior aspect of heart and result in atrial arrhythmias and pericarditis ?
