Key result
The incidence of interarterial coronary anastomoses in 75 normal and abnormal hearts was investigated using saline infusion and wax sphere injection, though specific results were not reported.
Observational (n=75)

Postmortem observations in 75 hearts leave open anastomotic incidence in normal vs diseased states; prospective studies needed.
It is generally recognized that interarterial coronary anastomoses of functionally significant size occur with great frequency in the presence of occlusive coronary artery disease and in other conditions such as anemia and cardiac hypertrophy in which myocardial anoxia may be present. Disagreement has been expressed by some investigators regarding the incidence of these anastomoses in normal and abnormal hearts. The problem has therefore been reinvestigated by means of a technic of infusion of saline solution and injection of wax spheres of known size. The results of these observations in 75 hearts are presented and their significance is discussed.

Bertram Pitt (1959) conducted an observational in Normal and abnormal hearts (occlusive coronary artery disease, anemia, cardiac hypertrophy) (n=75). Occlusive coronary artery disease, anemia, and cardiac hypertrophy vs. Normal hearts was evaluated on Incidence of interarterial coronary anastomoses. The incidence of interarterial coronary anastomoses in 75 normal and abnormal hearts was investigated using saline infusion and wax sphere injection, though specific results were not reported.
