Dysphagia due to compression of esophagus by enlarged left atrium (LA) due to mitral valve pathology is known. However, a functional mitral regurgitation (MR) as a consequence of aortic stenosis (AS) causing LA enlargement and dysphagia is rare and probably not reported. We present a case in which dysphagia was caused by functional MR secondary to AS. Dysphagia resolved significantly after isolated aortic valve replacement within postoperative hospitalization period and completely with improvement in diastolic function as evidenced by follow up echocardiographic examinations. Intraoperative transesophageal echocardiography was also used without any complication despite the patient having dysphagia after conducting preliminary endoscopic examination.
