Echocardiographic patterns after mitral annuloplasty.

18 adolescents and children who underwent mitral annuloplasty for severe mitral regurgitation were evaluated by echocardiography. In 7 patients studied preoperatively, mitral valve excursion ranged from 25 to 56 mm with E-F slopes from 92 to 160 mm/sec. 5 of the 7 patients showed mitral valve prolapse. The left ventricle was dilated in 6 and the left atrium was dilated in 4 patients. Postoperatively, the mitral valve excursion decreased ( range 15-26 mm; p less than 0.01) as did the E-F slope (range 44-100 mm/sec; 0.10 greater than p greater than 0.05). The prolapse pattern disappeared and the left heart chambers decreased in size. In these 7 patients and in 11 others studied postoperatively only, a common echocardiographic pattern was that of early anterior motion of the posterior mitral valve leaflet, which was not present preoperatively and was, therefore, tentatively ascribed to the technique of annuloplasty repair. No calciferation and no definite mitral steosis has occurred in the follow-up of these patients to date. Persistent left atrial/left ventricular dilatation appeared related to residual mitral regurgitation with or without atrial fibrillation.

Familial, balanced insertional translocation of chromosome 7 leading to offspring with deletion and duplication of the inserted segment, 7p15 leads to 7p21.

We report an uncle and niece with duplication and deletion, respectively, of segment 7p15 leads to 7p21 originating from a balanced, intrachromosomal insertion in their mothers. The proposita had prenatal and postnatal growth deficiency, retarded psychomotor development, microcephaly, wide cranial sutures, ocular hypertelorism, small palpebral fissures, apparently low-set and malformed ears, cleft palate, congenital heart defect, hypoplasia of the distal phalanx of first fingers, rocker-bottom feet, persistent cloaca, and imperforate anus. She died at three months. Her maternal uncle has duplication of this segment and is alive at 32 years. He has severe mental deficiency, but normal growth; communicating hydrocephalus was diagnosed at three months.
