Quadricuspid aortic valve associated with aortic insufficien
Quadricuspid aortic valve is one of the rarest forms of valvulopathy. It has been hypothesized that during the 5th week of embryogenesis, disruption of the mesenchymal ridges from fusing leads to this presentation.

This valvulopathy has been documented to have a predominance for men, with a mean presenting age between 45 and 60 years of age. The present case has been reported in the journal Annals of Cardiac Anaesthesia.

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.

Major takeaway:-
- Transesophaegeal echocardiography remains the gold standard in detection of quadricuspid aortic valve and identification of other possible cardiac lesions.

- Differential diagnosis include Aortic regurgitation, endocarditis, ankylosing spondylitis.
