Abstract:
1. A method of improving the efficacy of cardiac resynchronization therapy, the method comprising: temporarily intravascularly placing a first and a second ultrasonic transducer proximate first and second portions of the patient's heart, wherein the placement location of said transducers is static relative to said first and second portions; monitoring distance between the first and second ultrasonic transducers; deriving hemodynamic parameters based on the distance; adjusting a location for lead placement of a lead for the cardiac resynchronization therapy in response to the hemodynamic parameters while maintaining the first and second ultrasonic transducers in the static placement location proximate the portion of the patient's heart; repeating the monitoring, deriving and adjusting steps until a desired result is obtained; and removing the first and second ultrasonic transducers after the desired result is obtained.
