To the Editor.— We read with interest the report on a fistula originating from the left anterior descending coronary artery and terminating in the left ventricle by Housman and associates (240:372,1978). We recently reported a similar case in which the fistula was surgically closed and presented a movie of the same at the American Heart Association meeting in Anaheim, Calif, on Nov 17, 1975. 1 Our patient's fistula involved the main left anterior descending coronary artery and not a diagonal or contributing branch. Consequently, the authors' statement, "to our knowledge, no reported case of leftcoronary-artery... to left-ventricle... fistula exists in the English literature," is an incongruity. We congratulate the authors on their report but must point out that a more thorough perusal of the recent surgical literature would have discovered our recent contribution to the understanding of this interesting anomaly.
