Iatrogenic fistula from the aorta to the left marginal coronary vein.

We report the first documented case of iatrogenic aortocoronary fistula to the left marginal coronary vein following coronary bypass surgery. Unique clinical data, findings from catheterization, and angiographic features are presented and compared with those in the seven previously reported cases of iatrogenic aortocoronary venous fistulae after coronary bypass operations.
