Abstract

Introduction

Debilitating patient-related non-cardiac co-morbidity cumulatively increases risk for congenital heart surgery. At our emerging programme, flexible surgical strategies were used in high-risk neonates and infants generally considered in-operable, in an attempt to make them surgical candidates and achieve excellent outcomes.

Materials and methods

Between April, 2010 and November, 2013, all referred neonates (142) and infants (300) (average scores: RACHS 2.8 and STAT 3.0) underwent 442 primary cardiac operations: patients with bi-ventricular lesions underwent standard (n=294) or alternative (n=19) repair/staging strategies, such as pulmonary artery banding(s), ductal stenting, right outflow patching, etc. Patients with uni-ventricular hearts followed standard (n=96) or alternative hybrid (n=34) staging. The impact of major pre-operative risk factors (37%), standard or alternative surgical strategy, prematurity (50%), gestational age, low birth weight, genetic syndromes (23%), and major non-cardiac co-morbidity requiring same admission surgery (27%) was analysed on the need for extracorporeal membrane oxygenation, mortality, length of intubation, as well as ICU and hospital length of stays.

Results

The need for extracorporeal membrane oxygenation (8%) and hospital survival (94%) varied significantly between surgical strategy groups (p=0.0083 and 0.028, respectively). In high-risk patients, alternative bi- and uni-ventricular strategies minimised mortality, but were associated with prolonged intubation and ICU stay. Major pre-operative risk factors and lower weight at surgery significantly correlated with prolonged intubation, hospital length of stay, and mortality.

Discussion

In our emerging programme, flexible surgical strategies were offered to 53/442 high-risk neonates and infants with complex CHDs and significant non-cardiac co-morbidity, in order to buffer risk and achieve patient survival, although at the cost of increased resource utilisation.
