This series consists of four medical textbooks annotated by Dr. Bigelow in the course of his research, surgical, teaching and reviewing activities.

File 0094-2-0-4 contains, affixed to the inside front cover, a presentation card from the author addressed to Dr. Bigelow. Dr. Bigelow has annotated the card: "1994 - I was asked to write the book review by Anne [?] Sabaston - Annals Surg."

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.

This sub-series consists of patient case files illustrating ventriculomyotomies performed by Dr. Bigelow. Files pertaining to Dr. Bigelow's public patients are arranged alphabetically by patient surname. The remaining files are ordered by patient case number, which can be found on the physical records. Patient case numbers have been omitted from file titles to ensure compliance with Ontario’s Personal Health Information Protection Act, 2004 (PHIPA), but the original order has been retained.

This sub-series consists of patient case files illustrating mitral valvoplasties performed by Dr. Bigelow. The files are ordered by patient case number, which can be found on the physical records. Patient case numbers have been omitted from file titles to ensure compliance with Ontario’s Personal Health Information Protection Act, 2004 (PHIPA), but the original order has been retained.

This sub-series consists of patient case files illustrating aortic bicuspidization surgeries performed by Dr. Bigelow. Files pertaining to Dr. Bigelow's public patients are arranged alphabetically by patient surname. The remaining files are ordered by patient case number, which can be found on the physical records. Patient case numbers have been omitted from file titles to ensure compliance with Ontario’s Personal Health Information Protection Act, 2004 (PHIPA), but the original order has been retained.

This sub-series consists of patient case files illustrating mitral commissurotomy surgeries performed by Dr. Bigelow. The files are ordered by patient case number, which can be found on the physical records. Patient case numbers have been omitted from file titles to ensure compliance with Ontario’s Personal Health Information Protection Act, 2004 (PHIPA), but the original order has been retained.

This sub-series consists of patient case files illustrating pacemaker insertion surgeries performed by Dr. Bigelow. The files are ordered by patient case number, which can be found on the physical records. Patient case numbers have been omitted from file titles to ensure compliance with Ontario’s Personal Health Information Protection Act, 2004 (PHIPA), but the original order has been retained.

This sub-series consists of patient case files illustrating aorto-iliac arterial graft surgeries performed by Dr. Bigelow. The files are ordered by patient case number, which can be found on the physical records. Patient case numbers have been omitted from file titles to ensure compliance with Ontario’s Personal Health Information Protection Act, 2004 (PHIPA), but the original order has been retained.

This sub-series consists of patient case files illustrating combined aorto-coronary bypass/ internal mammary artery implant surgeries performed by Dr. Bigelow. The files are ordered by patient case number, which can be found on the physical records. Patient case numbers have been omitted from file titles to ensure compliance with Ontario’s Personal Health Information Protection Act, 2004 (PHIPA), but the original order has been retained. Files pertaining to Dr. Bigelow's staff patients are arranged alphabetically by patient surname.

Series consists principally of operation records and discharge summaries for a selection of Dr. Bigelow's surgical cases, organized by medical problem/ surgical procedure, and used as an aid for diagnosis and the determination of appropriate surgical procedures for use with new patients. These files were also used for research purposes in preparing case study reports and statistical analyses of specific surgeries. Some of the files are subdivided by facets of the medical problem/ surgical procedure exemplified: for example, File 0094-10-0-10 subdivides records exemplifying patent ductus arteriosus surgery into sections devoted to "division" and "ligation".
