These data suggest that the simple product of either Cornell or 12-lead voltage and QRS duration can identify left ventricular hypertrophy more accurately than can voltage or QRS duration criteria alone and may approach or exceed the performance of more complex multiple regression analyses.
Angioplasty of anomalous coronary arteries presents unique technical challenges. Correct guiding catheter selection is important to ensure adequate access to the anomalous vessel and to provide support to cross the lesion. A case of successful PTCA of a lesion in an anomalous right coronary artery arising from the left main coronary artery is presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
