Cardiac imaging news St. Jude Medical, Inc., an international medical device company, announced the release of its new products; ViewMate(TM) Z Intracardiac Ultrasound System and ViewFlex(TM) Plus Intracardiac Echocardiography (ICE) Catheter.

The new solutions offer better cardiac visualization.

The ViewMate Z System is designed for real-time image guidance and visualization of the cardiac anatomy. The system has the capability to offer fast, high-fidelity images that help direct diagnosis or therapy during complex electrophysiology procedures. The system is compatible with the new ViewFlex(TM) Plus ICE Catheter, which provides improved one-handed control, steering angles up to 120° and enhanced tip stability. The ViewMate Z System is designed to improve clinicians' visualization of cardiac anatomy and the effects of treatment in real-time.

The ViewMate Z System is considered one of the industry's smallest cart-based systems. It offers greater portability and optimizes vital lab space while decreasing obstructions in a clinician's workflow. The system was designed, developed and produced through St. Jude Medical's development and distribution agreement with ZONARE Medical Systems, a leading provider of high-end ultrasound systems.

Jane J. Song, president of the St. Jude Medical Atrial Fibrillation Division, said: "The ViewMate Z System offers clear visualization of patient anatomy and in turn provides the opportunity for a more effective procedure for the patient. It also has a unique ability to quickly produce exceptional images in a compact, cart-based system, improving on the effectiveness and efficiency of current ICE systems. This system is just the first of many products we intend to launch focusing on better imaging tools that put more control in the hands of physicians."

ZONARE Medical System's unique Zone Sonography(TM) enables the ViewMate Z System to provide unequalled image quality, performance and features, as well as advanced image processing capabilities without the limitations of current systems. Conventional ultrasound systems acquire and process echo data line-by-line and therefore are limited by the time needed for sound propagation in the patient's body. Zone Sonography technology is a new approach to echo data acquisition and image formation. It acquires ultrasound data very quickly in a relatively small number of large zones, each of which contain a volume of data equivalent to many lines in a conventional system. Zone Sonography technology acquires data up to ten times faster than conventional systems.

Ultrasound technology allows physicians to produce high-resolution intracardiac images. These images help guide doctors in performing different types of procedures such as radiofrequency (RF) ablation to treat arrhythmias and in closing defects such as patent foramen ovale (PFO), a small hole or opening in the wall between the two upper chambers of the heart (the atria). Moreover, clear views inside the heart also help reduce the time taken by physicians to perform such procedures, providing patients an opportunity to recover more quickly and potentially enhancing hospital productivity and performance.

Ultrasound imaging systems are designed to work by transmitting high-frequency sound waves through a transducer on the tip of a catheter. The sound waves reflect off structures inside the heart and the transducer collects and converts them back into electric energy to produce anatomical images. This ultrasound imaging process can also help lesssen unnecessary fluoroscopy (X-ray) exposure to the patient and clinician.
