Short term left ventricular assistive device use in postoperative pediatric patients with congenital heart disease / 中华胸心血管外科杂志

ABSTRACT

Objective To discuss the methods and experience of using short term left ventricular assist devices (LVADs) in patients after congenital heart disease(CHD) corrective surgery.Methods This study included 17 postoperative cases using short term LVAD support.The device used was a Maquet Rotaflow system, and the clinical patient data was collected and eval-uated retrospectively.Results The 17 patients were divided into two groups by the clinical outcome as follows 6 cases in the early death group(Group D) and 11 cases in the survival group(Group S).The pre-support time[(9.00 ±9.95)h vs. (23.83 ±13.23)h, P＝0.042]and the lactate level values[(4.01 ±2.15)mmol/L vs.(9.30 ±4.90)mmol/L, P＝0.045] were significantly lower and more favorable in Group S.Patients in Group S also received a longer support time than patients in Group D.Conclusion Using the Maquet Rotaflow system is generally safe and efficient, when used as a short term LVAD in postoperative pediatric patients.The selection of patients, the timing of support, and reasonable management were the keys to patient survival.
