Sunflower Health Plan Implantable Wireless Pulmonary Artery Pressure Monitoring (PDF) Form
Procedure is not covered
Various cardiac hemodynamic monitoring techniques have been investigated as a means to
remotely guide outpatient heart failure (HF) therapy, including implantable wireless pulmonary
artery (PA) pressure monitoring (e.g. C ardioMEMS®).1 The implanted device measures and
monitors daily PA pressure. The data is used by physicians for heart failure management with the
goal of reducing heart failure hospitalizations.2 Currently, only CardioMEMS has FDA approval,
and other devices (e.g. Chronicle®, ImPressure®) that monitor cardiac output through
measurements of pressure changes in the pulmonary artery or right ventricular outflow tract are
not supported by current evidence.3
Policy/Criteria
I. It is the policy of health plans affiliated with Centene Corporation® that the long-term safety
and effectiveness of implantable wireless pulmonary artery pressure monitoring has not been
proven for any indication, including the management of heart failure.
Background
Heart failure (HF) is one of the most common causes of hospitalization and readmission.2,4
According t o the Centers for Disease Control, an estimated 5.7 million adults in the United
States have HF. HF is a complex clinical syndrome that results from any structural or functional
impairment of ventricular filling or ejection of blood.5 The primary manifestations of HF are
dyspnea and fatigue, which may limit exercise tolerance, and fluid retention, which may lead to
pulmonary and/or splanchnic congestion and/or peripheral edema.6-7 The classification system
most commonly used to quantify the degree of functional limitation caused by HF is the New
York Heart Association Functional Classification system (NYHA).7 This system assigns patients
to one of four functional classes, depending on the degree of effort needed to elicit symptoms.7
Accurate monitoring of HF patients for exacerbations is important in an effort to reduce recurrent
hospitalizations and associated complications.5,8 Strategies to reduce hospitalizations in patients
with HF include optimizing evidence-based drug and device therapies, addressing causes of HF,
treating comorbidities, and improving management of care.9 It is proposed that monitoring
changes in pulmonary artery (PA) pressure (i.e., pressure the heart must exert to pump blood
from the heart through the arteries of the lungs) may provide a way to monitor changes in HF
resulting in improved HF management.2
The CardioMEMS HF System (St. Jude Medical) is Food and Drug Administration (FDA)
approved for wirelessly measuring and monitoring pulmonary artery pressure and heart rate in
NYHA Class III heart failure patients who have been hospitalized for heart failure in the
previous year.2-3 The hemodynamic data is used by physicians for heart failure management with
the goal of reducing hospitalizations related to heart failure.8

CLINICAL POLICY
Implantable Wireless Pulmonary Artery Pressure Monitoring
The CardioMEMS HF system provides daily PA pressure measurements, i ncluding systolic,
diastolic, and mean PA pressures.1 The system includes a dime sized PA sensor that is
permanently implanted in the pulmonary artery vi a fluoroscopy-guided right-heart
catheterization, a transvenous catheter delivery system, a patient home monitoring electronic
system, and a secure internet-accessible database that allows clinicians to access patient data.8,10
The home monitoring components include a pillow containing the antenna to capture the sensor
reading, a bedside monitoring unit to which the pillow is connected via a cable, and a remote
button. Each reading captures 18 seconds of pressure data that is wirelessly transmitted to a
secure database. The patient’s physician can use this information to optimize medical
management and potentially reduce the need for HF-related hospitalizations.2 The CardioMEMS
HF System is contraindicated for patients with an inability to take dual antiplatelet or
anticoagulants for one month post implant.
Sponsored by the manufacturer, the largest randomized single-blind trial, the Champion Trial
(CardioMEMS Heart Sensor Allows Monitoring of Pressure to Improve Outcomes In NYHA
Class III Heart Failure Patients), reported that transmission of PA pressure data from the device
reduced HF-related hospitalizations at six months (31% versus 44%).2,11-12 A later analysis
reported sustained reduction in HF-related hospitalization in the device-guided management
group compared with the control at 18-month average follow-up (46% versus 68%).14 During a
subsequent open access period with a mean duration of 13 months, pulmonary artery pressure
information was made available to guide therapy in the former control group. T he rate of
admission was reduced compared with that in the control group during the randomized access
period (36% versus 68%). The rate of device-related or system-related complications was 1%,
which was also the rate of procedure-related adverse events. H owever, concerns were raised by
the FDA regarding potential influence of the sponsor during the randomization period in this
study.12,15-16 In addition, study limitations include the lack of power to perform mortality
analyses, lack of baseline quality-of-life data, and potential for sponsor to influence patient
management.15
At this time, the current evidence is insufficient to support the use of ambulatory cardiac
hemodynamic monitoring using an implantable pulmonary artery pressure measurement device
in individuals with heart failure in an outpatient setting. Data on long-term health benefits
(including survival), safety issues, and quality of life are lacking. In addition, there is a lack of
evidence on the accuracy and clinical utility of the device for use in other NYHA functional
classifications.
American College of Cardiology Foundation
The American College of Cardiology Foundation/American Heart Association (ACCF/AHA)
2013 Guidelines for the Diagnosis and Management of Heart Failure in Adults recommend
monitoring with a pulmonary artery catheter in patients with respiratory distress or impaired
systemic perfusion when clinical assessment is inadequate.6 In addition, invasive hemodynamic
monitoring can be beneficial in certain patients with acute HF with persistent symptoms and/or
when hemodynamics are uncertain.6
The ACCF/AHA guidelines do not specifically address outpatient wireless implantable
pulmonary artery pressure monitoring, however, they note, “There has been no established role

for routine or periodic invasive hemodynamic measurements in the management of HF. Most
drugs used for the treatment of HF are prescribed on the basis of their ability to improve
symptoms or survival rather than their effect on hemodynamic variables. The initial and target
doses of these drugs are generally selected on the basis of controlled trial experience rather than
changes produced in cardiac output or pulmonary capillary wedge pressure.”6(p167)
European Society of Cardiology
According to the European Society of Cardiology (ESC), monitoring of pulmonary artery
pressures using a wireless implantable hemodynamic monitoring system (CardioMEMS) may be
considered in symptomatic patients with HF with previous HF hospitalization in order to reduce
the risk of recurrent HF hospitalization.17 This recommendation from ESC is considered a Class
IIB, level B recommendation (i.e., usefulness/efficacy is less well established by
evidence/opinion, and data has been derived from a single randomized clinical trial or large non-
randomized studies).17
National Institute for Health and Care Excellence (NICE)
Current evidence on the safety and efficacy of the insertion and use of implantable pulmonary
artery pressure monitors in chronic heart failure is limited in both quality and quantity.
Therefore, t his procedure should only be used with special arrangements for clinical governance,
consent and audit or research.17
