A 51-year-old male presented with a wound in his right hand that was suspicious for possible septic emboli of cardiac origin. With transesophageal echocardiography, the patient was found to have a rare quadricuspid aortic valve. This quadricuspid valve can present with variable symptoms and physical exam findings. Due to embryological defects, this pathology is associated with several other anatomical defects that are important to recognize prior to surgical intervention. Transesophaegeal echocardiography remains the gold standard in detection of quadricuspid aortic valve and identification of other possible cardiac lesions.
