Abstract
Despite successful primary percutaneous coronary intervention (PCI) for treatment of ST-segment elevation myocardial infarction (STEMI), myocardial salvage is frequently suboptimal resulting in large infarctions with increased rates of heart failure and death. Microvascular dysfunction after the procedure is frequently present and contributes directly to poor outcomes in STEMI. Pressure-controlled intermittent Coronary Sinus Occlusion (PiCSO) is a novel technology designed to mitigate microvascular dysfunction in STEMI. Non-randomized studies have suggested that PiCSO use during primary PCI in STEMI is safe, improves microvascular perfusion and reduces infarct size. Randomized trials are ongoing to investigate the safety and effectiveness of PiCSO in high-risk patients with anterior STEMI undergoing primary PCI.
