Resection of a right coronary artery aneurysm with fistula to the coronary sinus.

We are reporting the successful surgical management of a challenging right coronary artery aneurysm with a giant fistula into the coronary sinus. We performed fistula division, coronary sinus size reduction, and complete resection of the right coronary artery aneurysm with bypass to the posterior descending artery.

Effects of normothermic organ bath and verapamil-nitroglycerin solution alone or in combination on the blood flow of radial artery.

Objective: Radial artery pedicle tissue cooling during harvesting is one of the major causes of vasospasm. We aimed to compare the effects of the pedicle rewarming method, normothermic organ bath, and one of the most preferred topical antispasmodic agents, verapamil-nitroglycerin solution alone or in combination on the blood flow of radial artery.

Methods: Consecutively randomized patients (n=80) undergoing coronary bypass were organized as four equal-sized groups.

Right coronary artery with high takeoff.

Anomalous origin of the right coronary artery is an extremely rare anomaly. We describe the case of a patient whose right coronary artery was arising from the ascending aorta with high takeoff. We diagnosed the anomaly incidentally during the operation.

Normothermia is the key for the treatment of internal thoracic artery spasm.

Background: Free flow of the internal thoracic artery decreases commonly after harvesting because of spasm. Tissue heat loss is inevitable during surgery. The aim of this study was to compare the internal thoracic artery pedicle rewarming method with topical papaverine applications in different thermal conditions.
