Pulmonary artery (PA) pressure refers to the blood pressure in the pulmonary artery. Monitoring pulmonary heart patients using non-invasive cardiac output monitors and implantable hemodynamic sensors are among the promising novel technologies. These technologies offer help in clinical decision-making and imparting potentially better outcomes.  By monitoring pressure inside the pulmonary artery (the blood vessel that moves blood from the heart to the lungs) of the patients, a doctor can know when to make changes to the patient's treatment.

One such revolutionary invention for the patients with chronic heart failure is the pressure sensing device. This novel technology allows doctors to gain real-time information regarding pressure levels in pulmonary arteries. Based on electromechanical dynamics, the wireless cardiac monitor can relay the readings to the physicians. This helps reduce hospitalizations and clinic visits. CardioMEMS, the manufacturer of the device, has backed the device with clinical research. The patients who opted for device reported a 30% reduction in hospital readmissions over a period of just 6 months.

The device is implanted in the in the pulmonary artery using catheter, enabling direct measurement of pulmonary pressure. The first of its kind to gain approval from FDA provides a direct measure for the pulmonary pressure. Currently available in the USA, the device holds promise for the patients suffering from chronic heart failure worldwide.
