CRT-D
Also written as: CRT-D — Cardiac Resynchronization Therapy with Defibrillator
Cardiac Resynchronization Therapy with Defibrillator capability, a device combining biventricular pacing with defibrillation functions.
Full Definition
Cardiac Resynchronization Therapy with Defibrillator (CRT-D) is an advanced cardiac device that combines the benefits of biventricular pacing to improve cardiac synchrony with the life-saving capability of an implantable cardioverter-defibrillator. In geriatric cardiology, CRT-D devices are carefully considered given the complexity of implantation, potential complications, and patient life expectancy. The decision requires careful evaluation of functional status, comorbidities, and goals of care. These devices can significantly improve quality of life and reduce hospitalizations in appropriately selected elderly patients with heart failure and conduction abnormalities.
Usage
Usage note: Always hyphenate; distinguish clearly from CRT-P in clinical documentation.
