摘要:
目的 观察单纯主动脉关闭不全患者行瓣膜置换术后早、中期左心室结构和功能的可复性变化。方法 对39 例行瓣膜置换术的单纯主动脉瓣关闭不全患者行超声心动图检测,测量患者术后早期(术后3周~6个月)及中期 (术后1~2年)左心室舒张末期内径(LVEDD)、左心室收缩末期内径(LVESD)、左心室射血分数(LVEF)和短 轴缩短分数(FS)。并根据LVEDD将患者分为巨大左心室组(LVEDD≥70mm)和非巨大左心室组(LVEDD<70mm)。 结果 39例单纯主动脉瓣关闭不全患者,术后早期LVEDD和LVESD较术前降低,术后中期LVEDD和LVESD低于术后早 期(P<0.05);术后中期LVEF和FS高于术前和术后早期(P<0.05)。巨大左心室组患者术后中期的LVEDD低于早期 ,术后中期LVESD低于术前和术后早期;非巨大左心室组患者术后早期、中期LVESD均低于术前(P<0.05);两组 患者术后早期和中期的LVEDD低于术前,术后中期LVEF、FS均高于术前和术后早期(P<0.05)。非巨大左心室组患 者术前和术后早期LVEDD、LVESD均低于同期巨大左心室组,术后早期LVEF高于同期巨大左心室组(P<0.05)。结 论 单纯主动脉瓣关闭不全患者行体外循环下主动脉瓣膜置换术,可使术前扩大的左心室及受损的心功能得到改善 ,并应争取在LVEDD<70mm之前手术治疗。
Abstract:
Objective To investigate the changes of left ventricular structure and function in patients with valvular insufficiency after aortic valve replacement. Methods Closed change not all patients before and after surgery in different periods of the results of echocardiography before and after operation to observe the structure and function of left ventricle in 39 patients with aortic valve were retrospectively analyzed. Results The study group of preoperative left ventricular end diastolic diameter(LVEDD) and left ventricular end systolic diameter(LVESD) were higher than normal values,postoperative early stage LVEDD and LVESD were significantly reduced(P<0.05);early postoperative left ventricular ejection fraction(LVEF) compared with the preoperative decreased slightly(P<0.05). But after the mid operation,it was higher than preoperation(P<0.05). The left and right ventricular shpe and heart function of the left ventricular group were significantly larger than those of the left ventricular group after the operation(P<0.05). Conclusion Aortic valve replacement is safe and feasible,and improves left ventricular structure,morphology,and function in patients with preoperative left ventricular dysfunction. The patients with aortic valve insufficiency should be treated with active surgery before the end of the left ventricular end diastolic diameter(LVEDD<70mm),and the effect is better after operation.
