Reproducibility and Accuracy of a Portable System for Early Detection of Cardiac Dysfunction in Childhood Cancer Survivors

The clinical trial compares the reproducibility and accuracy of cardiac tonometry-based portable systems that may detect early cardiac dysfunction (SphygmoCor® Xcel and Oscar 2™ ambulatory blood pressure monitor) at home and in the clinic to currently available screening tests for heart failure including echocardiogram (echo) and cardiovascular magnetic resonance (CMR). The SphygmoCor® Xcel and Oscar 2™ systems may help detect cardiac dysfunction earlier than other available screening tests because it can be self-administered outside of the clinic. This study aims to test the accuracy and practicality of these devices in the clinic setting and at home.

About this study

Primary Objective(s)

Validate the accuracy of ejection fraction, as measured using a tonometry-based system (SphygmoCor® Xcel), in the clinic setting, and determine the reproducibility (Oscar 2™) at home.

Secondary Objective(s)

Determine the cost-effectiveness of tonometry-based screening in the clinic setting and at home.

Wireless Synchronized Cardiac Function Monitoring Device

Device

SphygmoCor® Xcel Oscar 2™ Ambulatory Blood Pressure Monitor

Primary outcomes

  1. Accuracy of ejection fraction (EF) in the clinic setting, and determine its reproducibility at home.

    Time frame: Up to 2 years

    Validate the accuracy of ejection fraction, as measured using a tonometry-based system (SphygmoCor® Xcel), in the clinic setting, and determine the reproducibility (Oscar 2™) at home.

Secondary outcomes

  1. Cost-effectiveness of tonometry-based screening in the clinic setting and at home.

    Time frame: Up to 2 years

    Will apply the sensitivity and specificity of echo, CMR, and the Oscar 2™ ABPM system (clinic, home-based) to compare the number of asymptomatic cardiac dysfunction cases identified via each method. Screening costs for echo and CMR, including costs of clinical services, will be obtained from the 2020 Centers for Medicare & Medicaid Services (CMS).
