[Van der Hoeve's syndrome with Ebstein's anomaly, and prolapse of the mitral and aortic valves: a case report].
A hitherto unrecognized case of van der Hoeve's syndrome complicated by Ebstein's anomaly, and prolapse of the mitral and aortic valves was reported. A 46-year-old woman presented with blue sclera, osteogenesis imperfecta and a hearing loss, which are typical symptoms of this syndrome. The electrocardiogram showed a type B WPW syndrome. The phonocardiogram showed a loud and widely split first heart sound, an accentuated protodiastolic extrasound, a decrescendo regurgitant systolic murmur, and a presystolic murmur. The x descent of the jugular phlebogram was obliterated by a markedly increased c wave. Based on M-mode and two-dimensional echocardiograms, 1) the interventricular septal motion was paradoxical and the closure of the tricuspid valve was delayed, 2) the septal tricuspid leaflet was displaced toward the apex from its normal annular insertion on the apical four-chamber view, 3) the three leaflets of the tricuspid valve were abnormally elongated, 4) the anterior mitral leaflet and the non-coronary cusp of the aortic valve were elongated and prolapsed. Doppler echocardiography detected severe tricuspid and mild mitral regurgitations. We suggest that the development of Ebstein's anomaly is possibly related to that of osteogenesis imperfecta genetically and that not only Ebstein's anomaly but a connective tissue disorder contributes to the elongated and prolapsed leaflets.
