Case history files typically contain standard medical documents including operation records, consultation records, autopsy reports, clinical histories, discharge summary reports, cardiovascular rounds reports, pathology reports, radiology reports, heart catheterization reports, angiograms, and electrocardiograms. The files also contain correspondence between Dr. Bigelow and medical colleagues and/or patients, and documents relating to patients' medical insurance and bills for service.

The materials in this series document developments in the medical and surgical treatment of specific cardiovascular defects and provide evidence of Dr. Bigelow's contributions to the innovation and development of such treatments.

Although most of the surgical procedures documented in this series were first performed predominantly on public ward patients, the files comprising this series are nearly exclusively those of Dr. Bigelow's private patients, whose medical records he was responsible for maintaining. Case files for public ward patients were maintained by the Toronto General Hospital's Department of Medical Records, and files compiled prior to 1980 have largely been destroyed.
