Résumé

Low flow alarms represent a management challenge in patients with left ventricular assist devices because they are often a consequence of complex patient-device interactions. We present a case of intermittent suction of the postero-medial papillary muscle into the left ventricular assist device inflow cannula during diastole, causing low flows. This case highlights the importance of a systematic approach and use of multiple investigation modalities in making an accurate diagnosis.
