目的 探讨成年人小主动脉瓣环者机械瓣膜置换术后的远期疗效,以指导临床实践.方法 2003年7月至2005年2月对36例小主动脉瓣环(直径≤19mm)的成年患者行人工机械瓣膜置换术.分别采用改良Manougnian法瓣环扩大后植入23 mm CarboMedics机械瓣膜14例(CM组);瓣环上主动脉瓣置换法直接植入19 mm CarboMedics Top Hat Supra-Annular Aortic机械瓣膜22例(CMSA组),于术前和术后6年评价两组患者的心功能,超声心动图检测左心室舒张末内径(LVDD)、室间隔厚度(IVST)、左心室后壁厚度(LVPWT)、收缩期主动脉瓣平均跨瓣压差(PGav)、左心室短轴缩短率(LVFS),计算左心室射血分数.并抽取20例健康成年人的超声心动图数据作为对照组,对三组资料进行对比分析.结果 术后6年与术前比较,除CMSA组的IVST[(10.37±2.06)mm比(11.03±2.45)mm]和LVPWT[(10.53±2.18)mm比(11.24±3.09)mm]差异无统计学意义外,CMSA组的心功能分级、LVDD、PGav、LVEF、LVFS和CM组的全部检测指标均较术前有不同程度改·善(P< 0.01或<0.05).术后6年CM组的PGav较CMSA组下降更明显[(9.24±5.93)mm Hg(1mmHg=0.133 kPa)比(24.30±12.50)mmHg],差异有统计学意义(P< 0.05);CM组术后6年各项指标与对照组比较差异无统计学意义,而CMSA组的IVST、LVPWT、PGav与对照组比较差异仍有统计学意义(P<0.05).结论 成年人小主动脉瓣环者机械瓣膜置换术后远期左心室功能多恢复良好,但行瓣环扩大术应植入较大内径的瓣膜,将有利于左心室形态的逆转.

Objective To evaluate the long-term effect after mechanical valve replacement in adult patients with small aortic root,and guide clinical practice.Methods From July 2003 to February 2005,36adult patients with small amtic root(diameter≤ 19 mm)received mechanical valve replacement,23 mm CarboMedics valve were implanted in 14 patients by using of Manougnian annulus enlargiW; technique(CM group),19 mm CarboMedics Top Hat Supra-Annular Aortic valve were implanted in 22 patients(CMSA group).All of the patients were examined for cardiac functions(CF),left ventricular end-diastolic diameter (LVDD),interventricular septal thickness(IVST),left ventricular posterior wall thickness(LVPWT),pressure gradients across aortic valve(PGav),and left ventricular fractional shortening(LVFS),calculating left ventricular ejection fraction(LVEF)before operation and 6 years after operation.Twenty healthy adults were as control group.Results Compared to the preoperation,there was no statistical difference in CMSA group in IVST[(10.37 ± 2.06)mm vs.(11.03 ± 2.45)mm]and LVPWT[(10.53 ± 2.18)mm vs.(11.24 ±degrees(P< 0.01 or < 0.05).PGav in CM group was lower significantly than that in CMSA group after 6 years [(9.24 ±5.93)mm Hg(1 mm Hg =0.133 kPa)vs.(24.30 ± 12.50)mm Hg],the difference was statistically significant(P < 0.05).The indicators in CM group were not statistically significant compared to control group,while CMSA group in IVST,LVPWT,PGav was significant difference(P <0.05).Conclusions The long-term effect after mechanical valve replacement is satisfied in adult patients with small aortic root,especially in left ventricular function.Line valve ring augmentation larger diameter valves implanted will help reverse the left vehicular morphology.
