Is it reasonable to treat all calcified stenotic aortic valves with a valved stent?
Stent misdeployment was constant in bicuspid valves and occurred in one-third of cases of tricuspid valves. Premature failure of implanted VS (secondary to valve distortion or traumatic injury to the leaflets by calcific excrescences) might be an important concern in the future.
Though all 4 nonphysician examinees performed better than would have been predicted by chance alone, none performed well enough to even fall within 8 SE below the passing thresholds; their performance was far below that of almost all physicians who completed the examination. Given that the nonphysicians relied heavily on the identifying cues in the phrasing of items and the manner in which response options were presented, the results affirm the notion that the ABFM certification examination is not primarily a measure of generic test-taking ability but measures information critical to the estimation of a family physician's knowledge sufficient for certification. Item analysis confirmed that items were well written, provided minimal cueing, and required medical knowledge to answer correctly.
