New Retrograde Coronary Sinus Perfusion Catheter without Requiring Right Atriotomy / 日本心臓血管外科学会雑誌

ABSTRACT

The current technique of retrograde coronary sinus perfusion (RCSP) has been provided double cannulation of the vanae cavae and isolation of these vessels, and right atriotomy. Most aortic valve and coronary artery bypass surgery are performed with single venous cannulation. We used a new RCSP catheter, Retroplegia (Research Medical Co.), and performed Cabrol procedure safely with single venous cannulation. This catheter can be cannulated to the coronary sinus through a right atrial purse-string suture without opening the right atrium. The occlusion balloon is inflated spontaneously by infusing the cardioplegic solution and occlude the coronary sinus adequately and nicely. This catheter has double lumen, one is for infusion of the cardioplegic solution, the other is for measurement of the coronary sinus pressure. We believe that this catheter is useful for RCSP of the cardiac surgery using single venous cannulation.
