Novadaq announced that it is introducing its newest product SPY-Q Image Analysis Tools, at the Society of Thoracic Surgery (STS) meeting in San Francisco, January 25-27,2008. During heart bypass surgery, SPY-Q along with SPY Imaging System (SPY) enables cardiac surgeons to objectively measure increases in fluorescence by comparing pre- and post-bypass images. Increases in fluorescence are measured in percentage and are associated with improvements in blood flow which are, in turn, indicative of overall perfusion to the heart achieved during the operation. “The goal of any bypass operation is to improve heart function by increasing perfusion to the muscle by creating a graft. The combination of SPY images and the new SPY-Q analysis tools provides more valuable data about blood flow and perfusion to heart muscle than ever before. Surgeons can use SPY-Q to compare pre-and post grafting images and thereby assess the improvements achieved by the bypass procedure. SPY and SPY-Q data can be used as a means of achieving the most durable and optimal procedure possible. Cardiac surgeons can also speak more specifically to a patient about the improvements that resulted from their surgery,” said Bruce Ferguson, MD, Professor and Chairman, Department of Cardiovascular Sciences, East Carolina Heart Institute at East Carolina University. The SPY-Q post-processing software analysis tools are upgrade to the SPY Imaging System. SPY-Q is mainly used during cardiac surgery but it can also be used in other surgical specialties. Novadaq opines that SPY-Q may significantly advance surgical procedures such as breast reconstruction, where adequate tissue perfusion is critical to achieving optimal outcomes and reducing the potential for costly and emotionally devastating post-operative complications.
