Abstract:
A 65-year-old woman presented with New York Heart Association class II-III symptoms, no overt signs of heart failure, and echocardiographic findings of a quadricuspid aortic valve, Hurwitz type C, with severe aortic regurgitation, dilated left ventricle (7 cm), and moderate left ventricular dysfunction (45%). She subsequently underwent tricuspidization of the valve at the level of the abnormal commissure with subcommissural annuloplasty. At her 6-week follow-up visit, the patient was in New York Heart Association class I, with reduction of left ventricular diastolic dimensions, trace aortic regurgitation, and good mobility of the leaflets.

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...
