Prospective Evaluation for Receiving SynFlow 3.0 Interventional Circulatory Support in High-risk PCI: A Randomized Controlled Trial

This study is conducted to compare the effectiveness of a new percutaneous mechanical circulatory support device called SynFlow 3.0 with VA-ECMO in high-risk percutaneous coronary intervetnion(PCI) patients. The objective of this study is to see if SynFlow 3.0 can provide similar or better support during high-risk PCI compared to VA-ECMO. Specifically, the following questions is to be answered in this study: Can SynFlow 3.0 provide sufficient hemodynamic support for patients during high-risk PCI and the effect be similar to VA-ECMO? Does SynFlow 3.0 offer other clinical benefits compared to VA-ECMO? By answering these questions, it will be determined if SynFlow 3.0 can be a viable alternative to VA-ECMO for patients undergoing high-risk PCI.
