Key result
Discrete subaortic stenosis in heart specimens was associated with increased mean mitral-aortic separation compared to normal specimens (4.9 vs 2.5 mm).
Why the study?
Is mitral-aortic separation increased in heart specimens with discrete subaortic stenosis compared to normal specimens?

Increased MAS in DSS specimens may guide surgical planning; leaves open whether findings translate to patient outcomes.

Is mitral-aortic separation increased in heart specimens with discrete subaortic stenosis compared to normal specimens?
Absolute Event Rate: 4.9% vs 2.5%
Mitral-aortic separation is significantly increased in discrete subaortic stenosis, providing important anatomical context for echocardiographic assessment and surgical resection.
Rosenquist et al. (1979) conducted an observational in Discrete subaortic stenosis (n=102). Discrete subaortic stenosis vs. Normal specimens was evaluated on Mean mitral-aortic separation (MAS). Discrete subaortic stenosis in heart specimens was associated with increased mean mitral-aortic separation compared to normal specimens (4.9 vs 2.5 mm).
