CCI study details aortic arch stent placement guided by 3D heart models
Two 3D-printed models of a teenager's heart were used to direct physicians as they successfully implanted an endovascular stent to correct an aortic arch hypoplasia. MRI data were used to create rigid and flexible radio-opaque models to facilitate simulation, according to the proof-of-concept study published in Catheterization and Cardiovascular Interventions.

Nutrition committee urges Americans to cut back on sugar
The Dietary Guidelines Advisory Committee on Thursday eased some restrictions on cholesterol and fat intake, saying that Americans should focus more on dietary patterns than on individual nutrients.

Lead aprons slash operators' radiation exposure, but patient dose is higher
Covering transradial PCI patients with a 0.5-mm lead shield reduced the amount of radiation received by operators by 75%, but the shield nearly doubled the patients' exposure. However, the trade-off may be worthwhile because operators deal with such procedures regularly, while exposure may be a one-time event for patients. The study, published in Catheterization and Cardiovascular Interventions, said "this balance has to be further confirmed and taken into account in every catheterization laboratory." (2/18)

CMS to cover outpatient use of Medtronic's drug-coated balloon catheter
Procedures using Medtronic's In.Pact Admiral drug-coated balloon catheter in an outpatient setting will receive Medicare coverage under a new reimbursement provision released by the CMS. The three-year supplemental reimbursement for the device will begin April 1. A decision from the CMS on whether to give supplemental reimbursement for the device's use in an inpatient setting is anticipated this summer. (Boston) (2/22)

Study links multivitamin-mineral use to lower risk of heart disease death
Women who had been taking multivitamin-mineral supplements for at least three years had a 35% lower risk of dying from heart disease over the next 18 years, compared with those who did not take them, according to a study in the Journal of Nutrition. The study, led by a registered dietitian from the NIH's Office of Dietary Supplements, found the results did not hold true for women who had been taking the supplements for less than three years or for men.

Most CVD clinical calculators overestimate risk, study finds
Four of five cardiovascular risk calculators overestimated patient risks, researchers wrote in an online report in the Annals of Internal Medicine. The study found that the Reynolds Risk Score was an exception, but it underestimated risk in women, while the 2013 American Heart Association/American College of Cardiology risk predictor, as well as three Framingham-based scoring tools, significantly overestimated risks.

Mesh-covered BMS may yield better one-year survival
The MGuard mesh-covered bare metal stent shows promise for reducing one-year mortality rates among STEMI patients treated with primary PCI, according to a study published in Circulation: Cardiovascular Interventions, although larger studies are needed for clarity. The polyethylene terephthalate mesh-covered device appeared to outperform conventional stents, but authors of the study cautioned that "endpoints other than ST-segment resolution should be considered exploratory and hypothesis generating." They called for large randomized trials to confirm whether MGuard would improve long-term survival rates. (2/19)

Dr. Joseph Loscalzo to deliver SCAI 2015 lecture on how network medicine could uncover personalized treatments for heart disease
Increasingly, physicians and scientists are discovering the complex connections among genes in the body that influence disease. These discoveries will enable personalized treatments in an emerging area of science known as network medicine. In his Mullins Lecture at SCAI 2015, "Network Medicine: A Systems Approach to Cardiovascular Disease Diagnosis and Management," Joseph Loscalzo, MD, PhD, chairman of the Department of Medicine, physician-in-chief of Brigham and Women's Hospital and Hersey Professor of the Theory and Practice of Medicine at Harvard Medical School, will discuss how advances in Big Data are enabling the new field of network medicine to uncover the complex pathways that influence disease. Find out more about Dr. Loscalzo's lecture and SCAI 2015.
