  • Modified Fontan Procedure for Patients with Heterotaxy Syndrome

    Objective To summarize the result and experience of modified Fontan procedure for patients with heterotaxy syndrome. Methods We retrospectively analyzed the clinical data of 17 patients with heterotaxy syndrome underwent cardiac operations in our hospital from September 2008 to November 2014. There were 11 males and 6 females at mean age of 4.7±2.5 years ranging from 3 to 10 years and at mean weight of 16.6±4.9 kilogram ranging from 10.6 to 27.0 kilogram. Two patients accepted modified Fontan surgery of stage one. The rest 15 patients accepted staging operation. They accepted modified Fontan surgery after they accepted a series of surgery like bidirectional Glenn procedure. Results There was no mortality in hospital. The peripheral blood oxygen saturation raised from 73%±12% to 91%±5%. There was no complications existing like thrombosis or severe arrhythmia. The follow-up duration was from 4 months to 6.5 years. There was 1 death during the time. The early and middle term mortality was 5.9% (1/17). Conclusions Single ventricle treatment remains the preferred procedure for patients with heterotaxy syndrome and its early and middle term results are satisfied.

  • Modified Fontan Procedure for Complex Congenital Heart Diseases

    ObjectiveTo review our clinical experience of modified Fontan procedure for complex congenital heart disease (CHD) in children. MethodsClinical data of 62 children with complex CHD who underwent modified Fontan procedure in Guangzhou Women and Children's Medical Center from May 2008 to December 2013 were retrospectively analyzed. There were 41 male and 21 female patients with their median age of 4 years(range, 16 months to 14 years) and body weight of 12.5 (8.9-49.5) kg. Diagnosis included functional single ventricle in 45 patients, transposition of the great arteries (TGA) with ventricular septal defect (VSD) and left ventricular outflow tract obstruction (LVOTO) in 6 patients, corrected TGA with VSD and LVOTO in 6 patients, double outlet right ventricle with severe pulmonary stenosis in 4 patients, and right ventricular dysplasia in 1 patient. Previous procedure included pulmonary artery banding in 10 patients, unilateral bidirectional Glenn shunt in 37 patients, and bilateral bidirectional Glenn shunt in 8 patients. Seventeen patients received single-stage modified Fontan procedure, and 45 patients received two-stage modified Fontan procedure. Extracardiac conduit was used in 56 patients, and lateral tunnel was used in 6 patients. Concomitant procedures included fenestration in 41 patients, atrioventricular valvuloplasty in 6 patients, and pulmonary artery angioplasty in 3 patients. ResultsTwo patients in both single-stage and two-stage groups died postoperatively with mortality of 11.8% and 4.4% respectively (P=0.299). Postoperative mechanical ventilation time, length of ICU stay, chestdrainage duration, postoperative hospital stay and morbidity were not statistically different between single-stage and two-stage group. Mean follow-up was 2.0 ±0.5 years (range, 3 months to 5 years). There were 2 late death in the singlestage group but no late death in the two-stage group. Growth of all survival children was good, and their exercise capacity significantly improved. Percutaneous oxygen saturation was higher than 90%. Echocardiography showed patent superior and inferior vena cava anastomosis without thrombosis, stenosis, atrioventricular valve regurgitation aggravation or pulmonary venous return obstruction. All survival patients were in New York Heart Association class Ⅰ or Ⅱ. None of the patients had arrhythmia, chronic effusion or protein losing enteropathy. ConclusionEarly and mid-term results of modified Fontan procedure were satisfactory for children with complex CHD. For children with high risk factors, staged Fontan procedure can reduce surgical mortality.

  • Risk Factors for Delayed Sternal Closure in Operation for the Neonates with Congenital Heart Disease

    ObjectiveTo analyze the risk factors for delayed sternal closure (DSC) in the operation for the neonates with congenital heart defects. MethodsWe retrospectively analyzed the case notes of the 203 neonates with congenital heart defect in our hospital between January 2010 and June 2014. There were 152 males and 51 females at age of 0-28 (17.68±8.62) days. The relative factors were analyzed by univariate and multivariate logistic regression. ResultsThese factors significantly correlated with DSC in univariate analysis:age at operation, premature, low weight (weight≤2.5 kg) at operation/weight at operation, RACHS-1, mechanical ventilation before operation, continuous use of intravenous cardiovascular drugs before operation, CPB time, aortic clamping time, total circulatory arrest with profound hypothermia. The results of logistic regression analysis showed that weight at operation/low weight, pre-operative mechanical ventilation, total circulatory arrest with profound hypothermia were independent risk factors for DSC. ConclusionWeight at operation/low weight, pre-operative mechanical ventilation, and total circulatory arrest with profound hypothermia are the independent risk factors for DSC in the operation for the neonates with congenital heart defects.
