A comparison of SPECT scanner photo-multiplier technology vs. the newer CZT detector SPECT technology, showing improvement in image clarity.

If the case went to court for whether positron emission tomography (PET) or single, photon emission computed tomography (SPECT) is better suited for myocardial perfusion imaging, experts say the current technology and developments on the horizon would result in a hung jury.

This comparison chart features three categories of stents: coronary, carotid and peripheral. We gratefully acknowledge the assistance of Mark Paquin, contributing editor and editorial advisory board member, in drafting specification questions, as well as the manufacturers whose contributions of specs have made this chart a useful tool for physicians.

The article by Frost & Sullivan market analyst Venkat Rajan is a discussion of the DES market and the author's perspectives and forecasts.

Angiography systems have been a diagnostic mainstay in cardiac cath labs for more than 50 years, playing a pivotal role in the diagnosis and treatment of heart and vascular diseases. Replacing imaging intensifiers with flat panel detectors (FPD) for angiography has broadened digital imaging’s role in the cath lab.

The use of embolic protection devices (EPD) during percutaneous cardiac procedures has helped reduce the number of complications due to debris being released into the bloodstream and causing blockages in smaller vessels. The devices are designed to capture and remove debris that may be dislodged during procedures.

There are three classes of EPD devices:

As the new editor of Diagnostic and Invasive Cardiology (DAIC), I hope communication will not be one-sided with me presenting or reviewing new technology on the market. I would like to hear from the readers — the end users of these products — to find out your thoughts. I would also like to find out what you consider as important issues, or what technologies you would like to hear more about.

September 4, 2008 – St. Elizabeth, in Cincinnati, OH, which serves more than 300 stroke patients annually, is the first community hospital in the U.S. to install the Aquilion ONE 320-slice CT system from Toshiba America Medical Systems in an ER setting.

September 1, 2008 - More than 22 million people worldwide suffer from heart failure, and most heart failure hospitalizations are due to excessive fluid accumulation in the chest cavity, and new data presented at the European Society of Cardiology Congress this week shows Medtronic’s devices equipped with OptiVol Fluid Status Monitoring Alerts may give advance warning of a patients’ worsening c

September 3, 2008 – Research published this week in the New England Journal of Medicine said patients with heart failure in whom an ICD is implanted and receive shocks for any arrhythmia have a substantially higher risk of death than similar patients who do not receive such shocks.

September 3, 2008 - Endologix Inc. yesterday said six-year patient follow-up data from the company’s Powerlink System pivotal clinical trial supporting the durability of the Powerlink System as a minimally invasive treatment for abdominal aortic aneurysm (AAA) and was published in the Journal of Vascular Surgery (September 2008).

September 3, 2008 – While a recent study into whether using unselected and selected bone-marrow derived cells can help with regeneration of heart tissue did not lead to significant improvement of LVEF and LV volumes in comparison to control group, there was a trend toward significant improvement of LVEF in patients with severely depressed baseline LVEF receiving either MNC or CD34 CXCR4 bone ma
