Cardiogenic dysphagia is a rare type of esophageal dysphagia caused by external compression of the esophagus by an enlarged left atrium. Long-term comparisons between the degree of cardiogenic dysphagia and heart failure have not been reported due to its low incidence. We hereby report the case of a 74-year-old woman with valvular heart disease, suspected of having oropharyngeal dysphagia following a recent intracerebral hemorrhage, who performed a swallowing function test. Videofluoroscopic swallowing study (VFSS) revealed a supraglottic penetration, confirming the oropharyngeal dysphagia. Furthermore, post-VFSS chest radiograph revealed esophageal residual barium, suggestive of reduced esophageal food transition secondary to external compression, at the level of the T6 vertebral body. Chest computed tomography showed mid-esophageal compression caused by left atrial enlargement. She had pulmonary edema which was managed with diuretics. Post-VFSS chest radiographs also revealed a direct association between the diameter of the esophageal barium residue and body weight. A reduction in body weight led to the resolution of the barium residue and vice versa. Development of cardiac dysphagia may be one of the signs of acute exacerbation of heart failure.
Objective To investigate esophageal motility disorders in patients with esophageal residual barium on chest x-rays after videofluoroscopic swallowing studies (VFSS) through high-resolution esophageal manometry (HREM).Methods We reviewed the records of 432 patients who underwent VFSS from September 2019 to May 2021, and 85 patients (19.7%) with large residual barium (diameter ≥1 cm) were included. As a result of HREM, motility disorders were classified as major or minor motility disorders according. Esophagogastroduodenoscopy and chest computed tomography results available were also reviewed.Results Among 85 patients with large residual barium in the esophagus, 16 patients (18.8%) underwent HREM. Abnormal esophageal motilities were identified in 68.8% patient: three patients (18.8%) had major motility disorders—achalasia (n=1), esophagogastric junction (EGJ) outflow obstruction (n=2)—and eight patients (50%) had minor motility disorders—ineffective esophageal motility (n=7), fragmented peristalsis (n=1). In those with normal esophageal motility, three patients of esophageal structure disorders (18.8%)—esophageal cancer (n=1), cardiogenic dysphagia (n=1), slight narrowing without obstruction of EGJ (n=1)—and two patients (12.5%) with chronic atrophic gastritis (n=2) were confirmed.Conclusion Esophageal motility disorders were identified in 68.8% of 16 patients with large esophageal residual barium with three patients in the major and eight patients in the minor categories. Residual barium in the esophagus was not rare and can be a sign of significant esophageal motility disorders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
