Abstract

A system comprising a multi-sensor catheter for monitoring a cardiac hemodynamic condition, e.g. heart failure. The multi-sensor catheter comprises multi-lumen catheter tubing, first and second optical pressure sensors, and respective optical fibers and connectors. For right heart and pulmonary artery catheterization, a flow-directed multi-sensor catheter comprises a guidewire lumen, inflatable balloon tip, and sensor locations are configured for placement of a sensor in each of the right atrium and pulmonary artery, for measurement of central venous pressure in the right atrium and a pulmonary artery pressure. An optical fiber for oximetry may be included. The outside diameter is small enough for insertion through a vein of the arm. For monitoring of a cardiac shunt, sensors are configured for measuring pressures upstream and downstream of the cardiac shunt, e.g. in left and right atria, or left atrium and coronary sinus.
