DISCOVER AUDICOR® TS

As a busy cardiologist caring for patients in your practice, you and your staff are on the leading edge of helping to diagnose and manage many of the 500,000 new heart failure cases identified each year. As you have experienced, cardiac resynchronization therapy (CRT) has emerged as an effective therapy option for NYHA class III or IV patients.

About 25% of heart failure patients also suffer from left ventricular (LV) mechanical dyssynchrony. The integrated function of all heart chambers are key determinants of heart failure. Nonuniformities of mechanical contraction, or dyssynchrony can lead to inefficient pump performance and energy expenditure in cardiac patients. Consequently, these patients experience suboptimal ventricular filling, a reduction in LV dP/dt (rate of rise of ventricular contractile force or pressure), prolonged duration of mitral regurgitation, and paradoxical septal wall motion. Ventricular dyssynchrony has also been associated with increased mortality in HF.

Acoustic cardiography offers a new innovative method of helping assess dyssynchrony and hemodynamic measures. Click here to learn more about how acoustic cardiography can help clinicians manage their heart failure patients.
