Cardiomems Use in Post Lung Transplant Patient Population

Purpose Little is known about the safety and impact of the pulmonary artery remote monitoring system, CardioMEMS, in reducing heart failure hospitalizations in patients following lung transplantation who developed heart failure with preserved ejection fraction (HFpEF). Methods A retrospective review of all patients who had cardioMEMS implanted after lung transplantation at our single center were reviewed. The total number of heart failure hospitalizations per patient month pre and post six months and one year of cardioMEMS were compared. Results A total of three patients with HFpEF following lung transplantation were included. Average mean pulmonary artery pressures at time of implantation were 33 ± 12 mmHG and reduced to 24 ± 2mmHg at 6 months. Overall, the total number of heart failure hospitalizations per patient month reduced from 0.28 to 0.17 at 6 months and from 0.19 to 0.14 at 1-year follow up. (Table) There was one procedure related complication with hemoptysis at time of CardioMEMS implantation, which was conservatively managed. Two patients have expired from pneumonia and respiratory failure. Conclusion CardioMEMS remote monitoring system may be promising to help decrease heart failure hospitalizations in patients following lung transplantation. The device can be successfully implanted in the transplanted lung. Further studies are needed to validate these preliminary findings.
