Coronary no-reflow is defined as inadequate myocardial perfusion of a given coronary segment without angiographic evidence of mechanical vessel obstruction. No-reflow is visualized angiographically as a reduction in thrombolysis in myocardial infarction (TIMI) flow grade and is typically accompanied by chest pain, electrocardiographic changes with ST-segment shift and possible hemodynamic compromise. No-reflow during primary percutaneous coronary intervention (PCI) results in increasing mortality and morbidity. Therefore, treatment of noreflow is associated with improved clinical outcomes. Generally, the treatment of no-reflow is based on pharmacotherapy. In this case, despite maximal pharmacotherapy and intraaortic balloon pump (IABP), refractory no-reflow accompanied with cardiogenic shock was successfully treated with percutaneous cardiopulmonary support (PCPS).
