Abstract
We present the case of an asymptomatic 40-year-old male patient who underwent a transoesophageal echocardiography examination for further evaluation of aortic regurgitation. On physical examination, an occasional diastolic murmur was detected. Transthoracic echocardiography demonstrated aortic regurgitation that was difficult to quantify accurately. A type F quadricuspid aortic valve was subsequently identified and confirmed by three-dimensional transoesophageal echocardiography.
