Hemodynamic goals have been used in the past to guide therapy in patients with heart failure (HF). For HF patients whose signs and symptoms of congestion do not resolve with initial therapy it appears reasonable to consider hemodynamic monitoring at experienced sites. It has been suggested that implantable hemodynamic sensors may enable frequent monitoring of hemodynamic changes in HF patients and be used in tailoring vasodilator. We present the first human case of radio-frequency based, wireless pressure sensor for the monitoring of pulmonary artery pressure in patients with advanced HF. This sensor is delivered into the pulmonary artery via percutaneous venous access.
