Why the study?
Does the DPTI:SPTI ratio predict left ventricular subendocardial ischemia in severe valvar and supravalvar aortic stenosis?
Population
9 dogs with acutely produced supravalvar aortic stenosis, 2 patients, and 18 control patients.
Comparison
Acute production of SVAS and measurement of… vs Baseline state (in dogs) and 18 control patients
Design
Preclinical

Low DPTI:SPTI ratios signal subendocardial ischemia risk in aortic stenosis; confirms predictive value from canine models in patients.
