Techniques to Overcome the Pushability of Robotic-Assisted PCI

Robotic-assisted percutaneous coronary intervention (PCI) was developed with a safety system that limits pushability as compared to manual PCI, thus preventing inadvertent deep delivery of the device and avoiding complications. This safety feature may limit robotic completion when performing intervention to more complex lesions that may require device delivery through calcified or previously stented lesions. In this article, we report three cases that highlight techniques to overcome this limited pushability, resulting in successful robotic completion of the procedures.
