BACKGROUND: The repair of a unicuspid aortic valve is quite challenging. METHODS: The repair of unicuspid aortic valve with the rigid internal geometric annuloplasty ring is shown. RESULTS: The patient was a 36 years old woman with severe aortic regurgitation and aneurysm of the ascending aorta. Echocardiography confirmed thickened unicuspid aortic valve. During the operation the unicuspid aortic valve was confirmed the raphe between the right coronary and left coronary leaflets was partially calcified. The raphe between right coronary and left coronary leaflet was cut open (commissurotomy). The nonocoronary (reference) leaflet admitted the 19 mm sizer. The leaflets were shaved and considerably thinned with sharp dissection. The calcified part of right-left raphe was resected. The leaflets were mobilised. The rigid internal geometric bicuspid ring was implanted under the valve leaflets. The ring post was used to recreate the commissure. The ascending aorta was replaced On postoperative echo the aortic valve was competent with the mean gradient of 27 mmHG. On follow up the gradient was reduced to the mean of 18mmHg. The video shows the technique of repairing the unicuspid aortic valve with rigid bicuspid geometric annuloplasty ring. CONCLUSIONS: The rigid internal geometric annuloplasty ring is a useful tool broadening the spectrum of aortic valve repair
