A Novel Device for Immediate Measurement of Arterial Lumen Cross-Sectional Area During Percutaneous Coronary or Peripheral Intervention Using Impedance Electrodes: The LumenRECON
This novel catheter uses electrical impedance to measure luminal cross-sectional area (CSA) prior to or after angioplasty for stent sizing and deployment. It also has potential applications for plaque characterization.

Comparison of the Histological Responses Observed at the Arterial Puncture Site After Employing Manual Compression and a New Collagen Technology to Achieve Hemostasis
The purpose of this study was to evaluate the pathobiological responses observed histologically in the skin tract and arteriotomy site 30 days after closure of porcine femoral arteries using a new sponge collagen from Datascope Corp. versus manual compression. Observations were made on 10 pigs that had femoral arteriotomy sites closed on one side using manual compression as a control while on the contra lateral side the sites were closed using a sponge collagen plug.

A Hand-Held Device to Measure Oxygen Uptake: Performance Characteristics, Patient Selection and the Propagation of its Measurement Error into Fick Cardiac Output Determinations
Abstract. Measured oxygen consumption rates (VO2) are being used less frequently for direct Fick cardiac output determinations during cardiac catheterization because the instruments that measure VO2 are usually cumbersome, expensive and difficult to use. A small, inexpensive VO2 device recently became available. Therefore, the aims of this report are: (1) to delineate the advantages and limitations that would affect its use during cardiac catheterization; (2) to define the patient population in which its use would be safe and effective; and (3) to estimate the accuracy of cardiac output determinations based on its VO2 measurements. The MedGem® is a fist-size device that measures VO2 as a patient breathes through it using either a facemask or mouthpiece. We evaluated it by measuring the external deadspace it imposes on the patient, by measuring the time required for each measurement, by determining its precision from repeated measurements on healthy volunteers and animals, and by developing a statistical model that calculates cardiac output error as a function of the random errors in the measurements of arterial and venous oxygen concentrations and VO2. Our experience indicates the MedGem is easy to operate and can be used for a wide spectrum of patients at rest including children with the ventilatory capacity to compensate for the added deadspace. Cardiac output determinations made with the MedGem?s measurements of oxygen uptake are clinically acceptable if the oximeter used to measure oxygen in arterial and mixed venous blood is also sufficiently accurate. Our statistical model illustrates strategies to minimize cardiac output error.

Wake Medical Center Sponsors RCIS Exam Review Course
On August 13th and 14th, 2005, Wake Medical Center (WakeMed) in Raleigh, North Carolina, sponsored a Registered Cardiovascular Invasive Specialist (RCIS) Exam Review course. The course was planned by Sherry Hunter, RN, RCIS (Figure 1), Cardiovascular Specialist III at the WakeMed Heart Center, and Allison Bordeaux, MEd, RD, LDN (Figure 2), Associate Director-Wake AHEC. The conference was held in the Andrews Center on the WakeMed campus.

Cath Lab & Beyond: A Training Program for Beginning Cath Lab Staff
Training and educating cath lab staff is an ongoing challenge in today?s rapidly changing and expanding interventional world. Many approaches exist to provide the information needed for nurses and technologists who work in this setting. One approach that has been successfully implemented in the Sacramento, California area is a program entitled Cath Lab & Beyond. Going strong since early 2001, Cath Lab & Beyond will be presented again May 8?11, 2007. It?s not too late to enroll!

Sunrise Hospital & Medical Center
What is the size of your cath lab facility and number of staff members? We currently have three coronary intervention rooms, one pediatric bi-plane interventional room, one peripheral vascular suite, one interventional electrophysiology (EP) laboratory, and one implant room. In March of 2005, two new state-of-the-art flat-panel GE rooms (Waukesha, WI) were added, bringing our total labs to seven. The cath lab has over 40 employees: 17 RNs, 8 RCISs, 8 RTs, and 10 CVTs. To augment our service line, we have a clinical educator, inventory specialists, EP coordinator, cath lab aide, scheduler, and clerical support staff. Staff members have been with the cath lab for time periods ranging from one year to over thirty years. We also have a 28-bed recovery room that consists of approximately 35 staff members.

In Search of the Vulnerable Stenosis: Imaging the Coronary Artery ? Lumen, Wall and Plaque Part 2 of 2
Tools to identify a vulnerable plaque, one which is likely to cause near-term acute myocardial infarction and adverse clinical sequelae, including sudden death, are currently limited to angiography and intravascular ultrasound (IVUS) imaging. Within the next decade, however, additional revolutionary, catheter-based techniques will emerge to identify, characterize, and treat the vulnerable plaque. This review will discuss three potential catheter-based modalities ? ultrasound, light, and thermal activity ? for imaging the vulnerable plaque, as well as current methods.
