Why the study?
Does subcostal transducer placement yield higher maximal aortic velocity measurements compared to left ventricular apex or suprasternal notch in dogs with subaortic stenosis?
Population
12 dogs with subaortic stenosis, sedated by iv administration of acepromazine and buprenorphine
Comparison
Doppler echocardiography using a 1.9-MHz… vs Transducer placed at the left ventricular apex…

Subcostal placement may optimize aortic velocity detection in dogs; leaves open prospective validation for clinical subaortic stenosis assessment.
Does subcostal transducer placement yield higher maximal aortic velocity measurements compared to left ventricular apex or suprasternal notch in dogs with subaortic stenosis?
The subcostal position is the optimal site for Doppler echocardiographic detection of subaortic stenosis and assessment of hemodynamic severity in dogs.
