Cardiac Package Reduces Unsuccessful Pacemaker Surgery


June 29, 2006

The Aplio CV all-digital ultrasound system is intended for advanced cardiovascular applications, allowing for improvements in a variety of cardiac procedures including stress echo, contrast harmonics and tissue Doppler imaging.

The system quantifies cardiac resynchronization therapy (CRT) and biventricular pacing, improving patient care by eliminating the risk of unnecessary pacemaker implant surgery — a procedure that still has a significant number of nonresponders. The new cardiac package will be available on all new Aplio CV systems and is a field upgrade for existing users.

The cardio package includes dyssynchrony imaging (DI) and tissue Doppler imaging quantification (TDIQ). DI is a rapid visual assessment to evaluate the electrical timing events within the heart. The DI technique aids cardiologists in the quantification of left ventricular mechanical dyssynchrony by providing a color-coded display that demonstrates the timing of events within the myocardium of the heart. Early mechanical events are “green” and severely delayed events are displayed “red,” allowing clinicians to identify the presence and severity of the patient’s dyssynchronous events.
