This study from South India demonstrates severe malnutrition in over half of the patients with CHD and is not always reversed by corrective surgery or intervention. Persistent malnutrition after corrective intervention is predicted by nutritional status at presentation, birth weight, and parental anthropometry.

Poor growth with underweight for age, decreased length/height for age, and underweight-for-height are all relatively common in children with CHD. The underlying causes of this failure to thrive may be multifactorial, including innate growth potential, severity of cardiac disease, increased energy requirements, decreased nutritional intake, malabsorption, and poor utilisation of absorbed nutrition. These factors are particularly common and severe in low-and middle-income countries.Although nutrition should be carefully assessed in all patients, failure of growth is not a contraindication to surgical repair, and patients should receive surgical repair where indicated as soon as possible.Close attention should be paid to nutritional support -primarily enteral feeding, with particular use of breast milk in infancy -in the perioperative period and in the paediatric ICU. This nutritional support requires specific attention and allocation of resources, including appropriately skilled personnel.Thereafter, it is essential to monitor growth and development and to identify causes for failure to catch-up or grow appropriately.

In the community setting of a developing country, clinical evaluation and pulse oximetry after birth had a very low sensitivity for detection of CHD. Though an abnormal screening warrants prompt echocardiography, a 6 week clinical evaluation is recommended to ensure that major CHD is not missed.

With increasing experience, neonatal cardiac surgery can be performed with excellent outcomes in developing countries with resource limitations. Infectious complications contribute significantly to morbidity and mortality, and improvements in infection-control practices should be emphasized to improve outcomes further.

Background:Management of native uncomplicated coarctation in neonates remains controversial with current evidence favoring surgery. The logistics of organizing surgical repair at short notice in sick infants with critical coarctation can be challenging.Methods and Results:We reviewed data of 10 infants (mean age of 2.9 ±1.6 weeks) who underwent catheter intervention for severe coarctation and left ventricular (LV) dysfunction between July 2003 and August 2007. Additional cardiac lesions were present in 7. Mean systolic gradient declined from 51±12 mm Hg to 8.7±6.7 mm Hg after dilation. The coarctation segment was stented in five patients. Procedural success was achieved in all patients with no mortality. Complications included brief cardiopulmonary arrest (n =1), sepsis (n = 1) and temporary pulse loss (n = 2). LV dysfunction improved in all patients. Average ICU stay was 5±3.4 days and hospital stay was 6.5±3.4 days. On follow-up (14.1±10.5 months), all developed restenosis after median period of 12 weeks (range four to 28 weeks). Three (two with stents) underwent elective coarctation repair, two underwent ventricular septal defect (VSD) closure and coarctation repair and one underwent pulmonary artery (PA) banding. Two patients who developed restenosis on follow-up were advised surgery, but did not report. Two (one with stent) underwent redilatation and are being followed with no significant residual gradients.Conclusion:Balloon dilation ± stenting is an effective interim palliation for infants and newborns with critical coarctation and LV dysfunction. Restenosis is inevitable and requires to be addressed.
