Device-based therapies for decompensated heart failure.

PURPOSE OF REVIEW: Despite improvements in medical therapies, patients with heart failure continue to suffer significant morbidity and mortality. Acute decompensated heart failure (ADHF) remains a common and serious medical condition with a myriad of implications on patient survival and quality of life, and heart failure related readmissions persist [1-3].

RECENT FINDINGS: From the detection of prehospitalization decompensation and inpatient management of ADHF to stabilization of cardiogenic shock and durable mechanical circulatory support, device-based therapies are utilized across the spectrum of heart failure management. At present, there are numerous device-based therapies commonly used in clinical practice and many more devices in the early clinical-trial phase aimed at attenuation of ADHF.

SUMMARY: In this review, we examine recent updates in the breadth and use of devices-based therapies in these three main domains: ambulatory heart failure, acute decompensated heart failure, and cardiogenic shock. Device-based therapies for decompensated heart failure will continue to grow in number, indication, and complexity, making recognition and familiarity with available technologies of increased importance for research and clinical practice.
