CRT Optimization - Current Status

 

  • The theory behind CRT optimization is that CRT can be programmed specifically to meet the needs of an individual patient in such a way that a non-responder or suboptimal responder will derive more benefit from CRT
  • This is done by optimizing AV and VV delay so that Aortic Velocity Time Integral (VTI) measured by Echo Doppler is maximized (VTI is correlated to Cardiac Output)
  • Due to high cost and complexity of Echo Doppler measurement, CRT optimization is rarely carried out
  • This results in a compromised treatment, high non responder rate and a reduced quality of life and life expectancy for CRT implanted patients

 

CRT Optimization Suggested by NICaSTM Cardiac Output

 

  • NICaSTM is a revolutionary device that is capable of providing a continuous Cardiac Output reading enabling a simple and cost effective CRT optimization
  • This enables an improved responder rate and an increased quality of life and life expectancy for CRT implanted patients 
  • NICaSTM converts changes in arterial electrical resistance to changes in blood volume by attaching two sensors to the patient’s wrist and opposite ankle, without requiring the patient to undress 
  • NICaSTM  can provide direct changes in CO without the need to measure correlated parameters such as Echo Doppler VTI
