Successful percutaneous coronary intervention with extracorporeal membrane oxygenation support after right coronary artery dissection in an eisenmenger syndrome patient

The presentation of coronary artery disease in a patient with Eisenmenger syndrome (ES) is relatively rare. Cardiogenic shock due to coronary artery dissection during percutaneous coronary intervention (PCI) can be more critical in these patients. Here, we report a case of successful PCI under mechanical circulation support in a patient with ES who experienced potentially fatal right coronary artery dissection. This case emphasizes that use of extracorporeal membrane oxygenation (ECMO) can lead to successful management of critical complication during PCI, and that the immediate decision to apply of ECMO is important in ES patients who face impending cardiogenic shock with acute heart failure.
