A simplified surgical technique combining endoloop occlusion and purse-string suturing can successfully exclude the left atrial appendage during off-pump CABG.
A standardized technique to permanently exclude the left atrial appendage during cardiac surgical procedures to potentially prevent stroke has never been established. We describe a simplified technique using a combination of endoloop occlusion with direct purse-string suturing supported with multiple teflon pledgets placed epicardially at the base of the appendage. The left atrial appendage is subsequently opened and decompressed to facilitate contraction and scarring, reducing or eliminating the possibility of recannalization. The technique was used successfully in 195 off-pump coronary bypass grafting patients with long-term echocardiographic follow-up.
