We aimed to assess the current nutritional practices in postoperative patients with Congenital Heart Disease.

Cross-sectional electronic survey was sent to members of The Pediatric Cardiac Intensive Care Society.

In Total, 52 members of the Pediatric Cardiac Intensive Care Society responded to the survey consisting of 14% paediatric intensivist, 53% paediatric cardiac intensivist, and 33% nurse/nurse practitioner with a median of 10 years of experience. There was an even distribution between intensivist (55%) and dietitian or nutritionist (45%) in nutrition management. Ninety-eight percent of respondents report that they would feed patients on inotropic or vasoactive support. Only 27% of respondents reported using indirect calorimetry in calculating resting energy expenditure which is the current gold standard. Academic hospitals compared to non-academic hospital were most likely to report feeding patients within 24 hours postoperative (p = 0.014). Having a feeding protocol was associated with feeding within 24 hours postoperative (p = 0.014) and associated with >50% goal intake by 48 hours postoperative (p = 0.025).

Substantial variation in feeding practice still exists despite the American Society for Parenteral and Enteral Nutrition guidelines from 2017. Report of institutional established feeding protocol was associated with increased early feeding and reaching goal feeds by 48 hours postoperative. Very few centres reported use of indirect calorimetry in postoperative paediatric cardiac intensive care patients and many respondents lacked knowledge about applications in this population. Additional work to determine optimal feeding pathways and assessment of caloric needs in this population is needed.

Single centre retrospective cohort study of patients aged 8–18 years who underwent surgical pulmonary valve replacement. The primary predictor was preoperative percent predicted peak oxygen consumption, and primary outcome was total hospital length of stay. Clinical, imaging, and cardiopulmonary exercise test data were reviewed and compared to total hospital length of stay. Cox proportional hazards regression was used to examine the association between total hospital length of stay and percent predicted peak oxygen consumption.

Three-hundred and seventy patients undergoing pulmonary valve replacement/conduit change between 2003 and 2017 at Boston Children’s Hospital were identified. Ninety had preoperative cardiopulmonary exercise tests within 6 months of surgery. Exclusion for inadequate exercise data (n = 3) and imaging data (n = 1) left 86 patients for review. Patients with percent predicted peak oxygen consumption ≥ 70% (n = 46, 53%) had shorter total hospital length of stay (4.4 days) than the 40 with percent predicted peak oxygen consumption <70% (5.4 days, p = 0.007). Median percent predicted peak oxygen consumption increased over sequential surgical eras (p < 0.001), but total hospital length of stay did not correlate with surgical era, preoperative left ventricular function, or preoperative right ventricular dilation.

Children undergoing surgical pulmonary valve replacement with better preoperative exercise capacity had shorter total hospital length of stay. Exercise capacity is a potentially modifiable factor prior to and after pulmonary valve replacement. Until more patients systematically undergo cardiopulmonary exercise tests, the full impact of optimisation of exercise capacity will not be known.

Vascular obstruction is one of the complications of radiofrequency ablation. Following our previous report on the use of radiofrequency energy for vascular closure in an animal model in this journal, we herein present the first ever in-human report.

The patient was a 3-year-old boy, who received a permanent endocardial pacemaker for congenital complete heart block. He also had a conical patent ductus arteriosus. The ductus was occluded with radiofrequency energy on the arterial side with no complications.

Closure of patent ductus arteriosus and probably other problematic small vessels could be achieved with radiofrequency energy. Further experience will elucidate the future scope of this novel technique.
