Abstract:
Unicuspid aortic valve repair relies on the principles of bicuspidization by creating a neo-commissure at 180° from the existing commissure, with pericardial patch interposition. We report a case of a 26-year-old patient with cor triatriatum and a severely regurgitating unicuspid valve. The left atrium membrane was resected. Aortic valve repair was performed creating a neo-commissure using a sliding plasty of the rudimentary right coronary cusp and patch reconstruction of the anterior part of the non-coronary cusp, protected by external subvalvular annuloplasty and hemi-root remodelling. We detail a repair technique of a partial autologous reconstruction approach for bicuspidization.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
