Two different methods of endomyocardial biopsy were evaluated. Compared to the Konno bioptome, a technique using a biopsy forceps originally designed for fiberoptic bronchoscopy and bronchial biopsy, passed through a No. 9 Fr. end-hole catheter, was easier to perform. The biopsy device is smaller than the Konno bioptome, has sharper teeth, and is easier to clean. The two techniques did not differ in arrhythmogenicity, hemorrhagic changes in the myocardium, or distortion of the specimens. Ventricular tachycardia as defined by three beats in a row was observed in 34 per cent. Epicardial hemorrhage was seen in nine of 14 animals, and the specimen distortion rate was 43 per cent. In one animal, perforation of the right ventricle and hemopericardium occurred.
对两种不同的心内膜心肌活检方法进行了评估。与Konno活检钳相比，一种使用最初为纤维支气管镜检查和支气管活检设计的活检钳的技术，通过9号法国端孔导管，操作更容易。该活检装置比Konno活检钳更小，齿更锋利，且更易于清洁。两种技术在致心律失常性、心肌出血变化或标本变形方面没有差异。连续三次心跳定义的室性心动过速在34%的病例中被观察到。14只动物中有9只出现心外膜出血，标本变形率为43%。在一只动物中，发生了右心室穿孔和心包积血。
