A 69-year-old male was evaluated for complaints of dyspnoea. Transthoracic echocardiography showed a moderate left ventricular systolic function. Although a significant aortic regurgitation was suspected, the valves could not be evaluated properly due to poor image quality. Consequently, transoesophageal echocardiography was performed which revealed a quadricuspid aortic valve (Fig. 1a and b). Only a moderate central aortic regurgitation was observed, valvular replacement was not indicated at the time. The ventricular dysfunction was found to be ischaemic of origin, the patient was treated successfully by percutaneous coronary intervention.

The aortic valve clearly consists of four symmetric cusps, giving the appearance of a four leaf clover.
