Heterotaxy Syndrome and Intestinal Rotation Abnormalities - A Prospective Study

Heterotaxy Syndrome

Pediatrics, Congenital heart disease, Heterotaxy syndrome, Intestinal malrotation

Infants with heterotaxy syndrome (HS) are born with an abnormal arrangement of organs along the right-left body axis. Abnormalities of intestinal rotation and fixation are commonly associated with HS. Malrotation is the most worrisome intestinal rotation abnormality (IRA). Advances in cardiac surgery have improved HS mortality such that there is increasing attention to IRA and their management. The objective of this research project is to prospectively observe a cohort of infants with HS and IRA and evaluate their long term outcomes. Specifically, the investigators would like to determine what is the natural history of asymptomatic IRA in patients with HS and what is the morbidity and mortality secondary to an elective Ladd procedure for asymptomatic IRA in a population with HS? The investigators plan a prospective, multi-center, observational study to follow this complicated group of patients. This will be a web-based database collected from major cardiac tertiary care centers in both Canada and the United States. Patients with HS will be recruited by their primary site and clinical data will be collected by their primary site prospectively throughout childhood until they are at least five years of age. This patient population will be followed by their own clinical care givers; this is not an interventional study. No additional clinic visits will be required and the patients will not have to be contacted. Patient medical records will be accessed by a member of the study team at the primary site at least once per year or more frequently if interventions are required or complications develop.
