An incidental finding during cardiac catheterization.

Coronary artery obstruction during cardiac catheterization is rare. It is a serious complication and has been reported to occur in 0.15 to 0.5% of cases. Thromboembolism, air embolism and coronary dissection have been described as the most common causes of intraprocedural coronary occlusion. Aortic valve masses can also cause coronary obstruction. We report the case of a young woman with a complication and an incidental finding during angiographic procedure. A surgical treatment was needed.
