A technique for transvenous endomyocardial biopsy of the right ventricle was developed and evaluated for safety and efficacy in healthy dogs and dogs with dilated cardiomyopathy positioned in lateral recumbency. This technique allowed acquisition of multiple biopsy specimens from the right ventricle of each of 22 hemodynamically normal dogs and 40 of 42 dogs with congestive heart failure. In 2 dogs with dilated cardiomyopathy, transvenous access to the right ventricle could not be achieved, but left ventricular biopsy was performed without complication. Complications were infrequent, and dogs recovered to at least their baseline status within 48 hours. Evaluation of the efficacy and complication rate of the procedure with each of the 2 biopsy instruments currently available identified no differences between them.
一种经静脉右心室心内膜活检技术得以开发，并在健康犬以及侧卧的扩张型心肌病犬中对其安全性和有效性进行了评估。该技术能够从22只血流动力学正常的犬的每只右心室获取多个活检标本，以及42只充血性心力衰竭犬中的40只的右心室活检标本。在2只扩张型心肌病犬中，无法实现经静脉进入右心室，但进行左心室活检未出现并发症。并发症很少见，犬在48小时内恢复至至少基线状态。使用目前可用的2种活检器械对该操作的有效性和并发症发生率进行评估，未发现它们之间存在差异。
