Dr Maude E Abbott (1869 to 1940) is the only Canadian and the only woman re
presented in Diego Rivera's great mural of the History of Cardiology in Mex
ico City. She gained this place among the world's famous physicians and sci
entists by her outstanding studies of congenital heart disease. Her atlas o
f 1000 cases with clinical, pathological and morphological findings is the
first systematic study of these anomalies. Dr Abbott developed a patho-phys
iological classification of cardiovascular defects fundamental for the deve
lopment of cardiac surgery. She also considered prevention by prenatal care
, recognizing possible genetic and environmental risk factors. Maude Abbott
was a thoughtful clinician and a brilliant scientist of incomparable indus
try. She leaves an unfinished legacy to make the prevention of congenital h
eart disease a reality.
