Double balloon angioplasty for unstentable large-caliber right coronary stenosis.

Despite newer lower-profile stent technologies, placing coronary stents may still remain challenging when vessels are extremely tortuous. We describe a case of a tortuous, very largecaliber right coronary with a near-180 degrees switchback "shepherd's crook" turn, which could not be stented, and for which double balloon angioplasty was successfully performed.

High levels of HDL cholesterol do not predict protection from cardiovascular disease in women.

Elevated levels >or= 60 mg/dL) of high-density lipoprotein cholesterol have been felt to be protective for cardiovascular disease in women. While cardiovascular disease is the leading killer of women in the United States, this is underrecognized, and women's symptoms are often atypical, leading to underdiagnosis. When high-density lipoprotein cholesterol is high, physicians may underestimate a woman's cardiovascular risk.
