Tricuspid valve repair in children with hypoplastic left heart syndrome during staged surgical reconstruction.

摘要: Background The purpose of this study was to determine the incidence moderate severe tricuspid valve regurgitation in children with hypoplastic left heart syndrome (HLHS) undergoing staged surgical reconstruction, assess mechanisms responsible, and evaluate efficacy repair. Methods Results We retrospectively reviewed clinical echocardiographic data 59 consecutive patients HLHS operated on at our institution. Patients a or degree (≥2+) demonstrated by color flow Doppler echocardiography before hemi-Fontan Fontan operation who underwent repair were included. coexisting atrioventricular septal defect excluded from study. Severity insufficiency graded scale 1 4+ mapping. Tricuspid morphology, regurgitation, right ventricular function assessed after valvuloplasty. Eight (8/59; 14%) found have minimum 2+ operations. In five eight (62%; Group A), be myxomatous, thickened, redundant. There multiple regurgitant jets three (60%) group. (37%; B), had normal appearance result lack complete leaflet coaptation. All valvuloplasty, all experienced decrease regurgitation. (62%) patients, there reduction two grades severity, (37%) one-grade improvement. stenosis not documented any seven (87%) as fair valvuloplasty improved good (71%) procedure. remaining patient both baseline Conclusions Moderate is common finding reconstruction can either abnormal morphology incomplete during stages carries high success rate associated function.
