Utility of a 0.035″ compatible rapid-exchange balloon (Metacross RX™) as a perfusion balloon in endovascular therapy compared with conventional percutaneous coronary intervention: A mini-review

Since endovascular treatment for peripheral artery disease has been rapidly and widely adopted as the preferred strategy, interventionists sometimes experience complications such as vessel perforation and severe dissections. We have a long-time inflation strategy for perfusion balloon catheters, which could be a solution for vessel complications in coronary sections, but not in peripheral sections. We invented a simple device for application as a perfusion balloon in peripheral sections, using a 0.035″ wire compatible rapid-exchange balloon Metacross RX™ (TERUMO, Tokyo, Japan) and reviewed this strategy using three cases as examples and compared them with the coronary perfusion balloon.
