Abstract
Congenital polyvalvular disease is a spectrum of macroscopic and microscopic anomalies of the 4 valves of the heart. It is most commonly associated with chromosomal abnormalities, such as trisomy 13 and trisomy 18. Kowal-Vern et al. and Bartram et al. describe a total of 4 cases of congenital polyvalvular disease in patients with normal chromosomes by standard banding pattern analysis. Each of their patients, however, had associated extracardiac anomalies. Of the 8 previously reported cases of congenital polyvalvular disease with no extracardiac anomalies, chromosome analysis was not performed. We report a prenatally diagnosed case of polyvalvular disease with normal chromosomes and no extracardiac anomalies.
