CardioMEMS Heart Failure System: An Up-to-Date Review

Abstract

Heart failure (HF) continues to represent a significant public health concern. While patients with HF with reduced ejection fraction (HFrEF) face a high risk of arrhythmias, both patients with HFrEF and HF with preserved ejection fraction (HFpEF) experience fluid overload, leading to repeated hospitalizations. Traditional monitoring methods have limited ability to manage HF exacerbations preemptively. However, the CardioMEMS™ (Abbott Laboratories, Chicago, IL) HF system, an implantable microelectromechanical sensor, has emerged as an innovative solution, enabling real-time remote monitoring of pulmonary artery pressures (PAPs). CardioMEMS has significantly reduced HF-related hospitalizations and improved patient quality of life (QOL) by facilitating early intervention before clinical symptoms. This article explores the technical specifications, clinical efficacy, integration into clinical practice, and economic impact of the CardioMEMS system. Furthermore, we discuss the challenges and limitations associated with its widespread adoption and propose considerations for future research to enhance its cost-effectiveness and accessibility in diverse healthcare settings.
