本文报告7例应用经皮穿刺法的心内膜心肌活检术,共取得右心标本24块,其中20块为心肌组织,成功率为86%。在操作上采用经颈内静脉途径插入活检钳方法,不仅较易进入右房及右室,且心律失常发生率低,活检钳头易抵达室间隔中上部,钳取心内膜心肌组织的范围较大.一例 IHSS 患者于手术后出现完全性右束支传导阻滞及一过性 A 型预激综合征的心电图表现.心肌病的鉴别诊断不能仅凭病理所见,而必须结合临床资料综合考虑才能提高确诊率。
This article reports 7 cases of endocardial biopsy using percutaneous puncture method, a total of 24 right heart specimens were obtained, of which 20 were myocardial tissue with a success rate of 86%. In the operation by the jugular vein approach to insert the biopsy forceps approach, not only easier to enter the right atrium and right ventricle, and the incidence of arrhythmia is low, biopsy forceps easily reach the upper part of the interventricular septum, clamp the scope of endocardial myocardial tissue Larger.A case of IHSS patients with complete right bundle branch block after surgery and ECG of transient pre-excitation syndrome type A. Cardiomyopathy can not be differentiated by pathological findings, but must be combined with clinical data Consider to improve the diagnosis rate.
