Case Study 9-1: PTCA （经皮冠状动脉内成形术）and Echocardiogram（超声心动图） A.L., a 68-year-old woman, was admitted to the CCU with chest pain, dyspnea（呼吸困难）, diaphoresis（发汗）, syncope（昏厥）,and nausea（恶心）. She had taken three sublingual（舌下的） doses of nitroglycerine（硝化甘油） tablets（片剂） within a 10-minute time span（跨距） without relief before dialing 911. A previous stress test and thallium（铊） uptake（摄取） scan suggested cardiac disease. Her family history was significant for cardiovascular disease（心血管疾病）. Her father died at the age of 62 of an acute myocardial infarction（急性心肌梗塞）. Her mother had bilateral carotid endarterectomies（双侧颈动脉内膜切除术）and a femoral-popliteal bypass（股腘动脉旁路术）procedure and died at the age of 72 of congestive heart failure（充血性心力衰竭）. A.L.s older sister died from a ruptured aortic aneurysm（主动脉动脉瘤破裂） at the age of 65. Her ECG（超声心动图） on admission（入院时） presented tachycardia（心跳过速） with a rate of 126 bpm（每分钟心跳次数） with inverted T waves. A murmur（心脏杂音） was heard at S1（第一心音）. Her skin color was dusky to cyanotic（发紫的） on her lips and fingertips. Her admitting diagnosis（入院诊断） was possible coronary artery disease（冠心病）, acute myocardial infarction（急性心肌梗塞）, and valvular disease（心瓣膜病）. Cardiac catheterization（心导管术） with balloon angioplasty (PTCA) （经皮冠状动脉腔内成形术）was performed the next day. Significant（显著的） stenosis（狭窄） of the left anterior descending coronary artery （冠状动脉前降支）was shown and was treated with angioplasty（血管成形术） and stent placement（支架放置）. Left ventricular function（左心室功能） was normal. Echocardiogram（超声心动图）, 2 days later, showed normal-sized left and enlarged right ventricular cavity. The mitral valve（二尖瓣） had normal amplitude of motion（正常运动幅度）. The anterior and posterior leaflets（小叶） moved in opposite directions during diastole（舒张期）. There was a late systolic（收缩期的） prolapse（脱出） of the mitral leaflet（二尖瓣瓣叶） at rest（静止）. The left atrium（左心房） was enlarged. The impression of the study was mitral prolapse（二???瓣脱垂） with regurgitation（回流，反流）. Surgery was recommended. 翻译：AL，一个68岁的女子，被送往胸
