Imaging findings
A comparison chest radiograph showed a new device implanted on the right side, in addition to an existing left pectoral implantable cardioverter-defibrillator (ICD). The new device had a stimulation lead extending to the vagus nerve and a conventional sensing lead positioned in the right ventricle.
Key takeaways
The CardioFit system is an investigational device designed to treat heart failure by stimulating the vagus nerve, aiming to increase parasympathetic stimulation to the heart and potentially improve cardiac function. This device is currently undergoing clinical trials (e.g., INNOVATE-HF trial) in the US.
