Why the study?
Does left ventricular ejection time correlate with intraventricular pressure gradient in muscular subaortic stenosis?
Does left ventricular ejection time correlate with intraventricular pressure gradient in muscular subaortic stenosis?
The study demonstrates that intraventricular pressure gradients in muscular subaortic stenosis directly correlate with prolonged left ventricular ejection time, supporting true outflow obstruction rather than catheter entrapment.
No takes yet. Share an insight, caveat, or question.
Supports true obstruction over artifact in muscular subaortic stenosis; hypothesis-generating and requires prospective validation.
Wigle et al. (1967) studied this question.
