A 45-year-old man suffering from severe heart failure due to mitral regurgitation and atrial fibrillation was admitted to our hospital. He underwent intracoronary thrombolysis for left anterior descending artery 10 years ago and stent insertion for right coronary artery 3 years ago. We performed mitral annuloplasty using a Carpentier-Edwards Physio ring 28mm and modified maze procedure. The modified maze procedure consists of right sided left atriotomy extended to the left margin of the left pulmonary vein orifices and cryoablation applied to the remnant of the left atrial wall between the left upper and lower pulmonary vein orifice and cryoablation applied to the right atrial isthmus. These procedures could be effective for endstage heart failure.
一名45岁男性因二尖瓣反流和心房颤动导致严重心力衰竭入住我院。他10年前接受了左前降支冠状动脉内溶栓治疗，3年前接受了右冠状动脉支架置入术。我们使用28mm的Carpentier-Edwards Physio环进行二尖瓣环成形术，并实施了改良迷宫手术。改良迷宫手术包括将右侧左心房切开术延伸至左肺静脉口的左边缘，对左上、下肺静脉口之间的左心房壁残余部分进行冷冻消融，并对右心房峡部进行冷冻消融。这些手术可能对终末期心力衰竭有效。
