A method for administering cardioplegia and venting the left heart that utilizes a single cannula in the aortic root and minimizes the risk of air entering the left heart is presented. This technique permits precise control of flow and pressure of the cardioplegic solution. Left heart decompression is accomplished by siphon drainage with controlled negative pressure. This method effectively vents the left heart while preventing aspiration of air around the cannula insertion site or retrograde through an opened coronary artery with a nonocclusive proximal lesion during the construction of the distal anastomoses.
提出了一种在主动脉根部使用单个插管进行心脏停搏液灌注和左心排气的方法，该方法可将空气进入左心的风险降至最低。这种技术能够精确控制心脏停搏液的流量和压力。左心减压通过可控负压的虹吸引流来实现。该方法能有效排出左心内的气体，同时防止在构建远端吻合口时，空气在插管插入部位周围被吸入或通过有非闭塞性近端病变的开放冠状动脉逆行进入。
