Late pulmonary infarctus in patient with cardioMEMS pulmonary artery pressure sensor

A 63 year-old male with severe heart failure was implanted with a CardioMEMS™ pulmonary artery pressure sensor and received usual anti-aggregation therapy. Six months later, he was admitted for chest pain without respiratory or hemodynamic compromise. The CT-scan showed recent complete thrombosis of the pulmonary branch downstream of the CardioMEMS™. His progression was favorable under curative anticoagulation. Data from the sensor remained usable without significant variation during the episode. Late pulmonary events can occur in the presence of a CardioMEMS™ device. Thus use of a CardioMEMs device should be carefully discussed, particularly when systematic anticoagulation is not possible.
