We report a clinically significant right-to-left intracardiac shunt through a patent foramen ovale, diagnosed during investigations for hypoxemia and left ventricular dilation on the late postoperative period of a HeartMate3 implantation. We discuss diagnostic pitfalls and haemodynamic influences in this scenario, as well as the possibility of successful percutaneous treatment.
