Don’t Judge a Plant by Its Flowers

You may have noticed that there are lots of different kinds of plants in your own backyard or neighborhood, and you may even have heard of the concept of evolution. But have you ever wondered what forces have contributed to creating all these plants, with different shapes and colors, all over the world? Or how scientists hope to understand and explain how so many kinds of life came to be over m...

Don't judge a book by its cover: don't judge stenosis severity solely by intravascular ultrasound.

In this issue of Circulation: Cardiovascular Interventions, Kang et al1 compare intravascular ultrasound (IVUS) parameters against a gold standard of fractional flow reserve (FFR) for evaluating intermediate stenoses. Their work adds another piece of evidence to a debate whose outcome is fundamentally changing interventional cardiology. As encapsulated by the title of the “FFR versus Angiograph...

Don't Judge Software by Its (Code) Coverage

This position paper argues that using code coverage metrics to evaluate the completeness of test cases as prescribed by e.g. ISO26262, is insufficient in a safety context. On the other hand it is impossible to execute test cases that achieve 100% completeness with respect to all possible input data combinations testing all requirements. We propose that existing requirements on code coverage sha...

Don’t judge the myocardium by its cover

A 51-year-old female presenting with fatigue demonstrated cardiac enlargement on her chest x-ray. The electrocardiogram was normal (Fig. 1). However, echocardiography suggested asymmetrical hypertrophic cardiomyopathy. Cardiac magnetic resonance (CMR) imaging was performed for further evaluation. The cine images showed a maximum wall thickness of 28mm at the mid anterolateral segment (Fig. 2a; ...
