and/or modification of dietary sodium. When a child’s fluid intake is limited, it<br />

becomes difficult to provide adequate energy intake (4,5). See Appendix T <strong>for</strong><br />

in<strong>for</strong>mation about increasing the energy density of <strong>for</strong>mula.<br />

CHF can affect either side of the heart. In children <strong>with</strong> CHD, right-sided CHF is<br />

the most common. <strong>Children</strong> <strong>with</strong> right-sided failure may have gastrointestinal<br />

malabsorption, vomiting, and diarrhea mimicking the common symptoms of milk<br />

allergy or <strong>for</strong>mula intolerance. <strong>Children</strong> <strong>with</strong> left sided failure may have tachypnea<br />

(rapid breathing), tachycardia (rapid heart beat), and/or diaphoresis (sweating)<br />

(4). Infants <strong>with</strong> both types of failure tend to tire easily and may not be able to<br />

breastfeed or bottle-feed <strong>with</strong>out developing shortness of breath (4, 5).<br />

Malabsorption has been suggested as a cause <strong>for</strong> growth failure. Some studies<br />

report fat and/or protein malabsorption in infants <strong>with</strong> CHF while others report<br />

varying degrees of fat malabsorption in infants <strong>with</strong> all types of CHD (2,4). Protein<br />

losing enteropathy is a condition reported in patients <strong>with</strong> increased right-sided<br />

heart pressures, especially those young children who have undergone the Fontan or<br />

Bidirectional Glenn procedure (6).<br />

Decreased perfusion to the gastrointestinal (GI) tract often leads to delayed gastric<br />

emptying, vomiting and gastroesophageal reflux (GERD) in infants and children<br />

<strong>with</strong> moderate to severe heart failure (6). Reflux can be managed <strong>with</strong> medications<br />

and/or an adjustment to the infant’s feeding (6). Surgical intervention (gastric<br />

fundoplication) is effective in managing severe reflux in order to promote weight gain<br />

in children <strong>with</strong> severe congenital heart defects (7).<br />

Reduced blood flow to intestinal tract may occur when the body shunts blood away<br />

from the gut to preserve heart and brain function in the child <strong>with</strong> moderate to<br />

severe heart failure (6). This reduction in blood flow can cause early satiety, nausea<br />

and vomiting which in turn may result in decreased nutrient absorption (6).<br />

Often, complications can arise after cardiac surgery. One such complication is<br />

the <strong>for</strong>mation of a chylothorax. When the thoracic duct or tributaries are injured<br />

during extra pericardial operations, chyle can accumulate in the pleural spaces.<br />

This is especially common in surgeries involving mobilization of the aortic arch<br />

or coarctation of aorta as well as <strong>with</strong> a Blalock-Tausig shunt. A chylothorax can<br />

also occur spontaneously due to increased pressures <strong>with</strong>in the heart itself (8,9).<br />

Conservative nutrition treatment of a chylothorax includes the use of very low fat<br />

diet. Infants and young children may require specialized <strong>for</strong>mulas containing high<br />

amounts of medium chain triglycerides (MCT) (6). Medium chain triglycerides bypass<br />

the lymphatic system and are directly absorbed into the bloodstream via the<br />

portal venous system; there<strong>for</strong>e, reducing chyle production and slowing/eliminating<br />
