Septal branch right ventricular fistula: a complication in coronary artery snaring

We report a septal branch right ventricular fistula complicated after coronary snaring in coronary artery bypass surgery without aortic cross-clamping. The tip of the needle of the snaring suture is made blunt in order to decrease the risk of mechanical injury, but trauma to the septal branch is possible. This rare complication of snaring should be taken into consideration in performing aortic nonclamping coronary artery bypass surgery.
