[Remote invasive monitoring of pulmonary artery pressures in heart failure patients: Initial experience in Portugal in the context of the Covid-19 pandemic].

ABSTRACT:

Background

Decompensated heart failure (HF) is associated with poor short- and long-term prognosis. Remote invasive monitoring of pulmonary artery pressures (PAP) enables early detection of HF decompensation, before symptoms occur, and may improve clinical outcomes. We aimed to describe our initial experience with the use of the CardioMEMS™ remote monitoring system in patients with HF, including its safety and effectiveness.

Methods and results

Five patients with HF in New York Heart Association class III and at least one hospitalization due to decompensated HF in last 12 months, who underwent invasive remote monitoring of PAP, were included in this prospective registry. The median age was 66.0 years (interquartile range [IQR] 50.5-77.5 years), 80.0% were men and all had HF with reduced ejection fraction. The pulmonary artery (PA) sensor was placed in a left PA branch in all patients and no major procedural complications occurred. In median follow-up of 40 days (IQR 40-61 days), a total of 271 pressure readings were transmitted, patient compliance was 100% and freedom from sensor failure 98.1%. In three patients, PAP remained within the goal during follow-up. Two patients presented an increase in PAP to values above the targets, despite the absence of symptoms worsening. These required dietary and diuretic dose adjustment, without the need for outpatient clinic visits, which reduced PAP. No hospitalizations for HF or deaths occurred during follow-up.

Conclusion

Hemodynamic-guided HF monitoring was safe and effective and may be a useful adjunctive tool to the standard-of-care management in selected HF patients, particularly in the context of the COVID-19 pandemic, where a reduction in the number of health care visits may be desirable.
