Congenital mitral stenosis. Anatomical and functional assessment by echocardiography.
Key result
Two-dimensional echocardiography reliably delineated mitral abnormalities in congenital mitral stenosis, whereas digitised M-mode was generally unreliable for assessing obstruction.
Why the study?
Does two-dimensional and M-mode echocardiography reliably assess anatomical and functional severity in children with congenital mitral stenosis?
Population
Children with congenital mitral stenosis.

Implication
Caution against M-mode for obstruction severity in congenital mitral stenosis; leaves open prospective validation of 2D echocardiography.

Type
Observational (n=10)
Structured PICO

P
Population
Children with congenital mitral stenosis undergoing anatomical and functional assessment by echocardiography.
E
Exposure
Two-dimensional echocardiography and digitised M-mode left ventricular echocardiography
C
Comparator
Cardiac catheterisation (used as a reference for gradients in a subset of patients)
O
Outcome
Assessment of the severity of inflow obstruction, mitral annular size, and morphology of the valve and subvalvular apparatussurrogate
Two-dimensional echocardiography is a reliable imaging modality for delineating anatomical abnormalities in congenital mitral stenosis, whereas M-mode echocardiography is generally unreliable for assessing the severity of obstruction.
Cite This Study
Smallhorn et al. (1981) conducted an observational in Congenital mitral stenosis (n=10). Echocardiography (Two-dimensional and digitised M-mode) was evaluated on Assessment of severity of inflow obstruction and anatomical morphology. Two-dimensional echocardiography reliably delineated mitral abnormalities in congenital mitral stenosis, whereas digitised M-mode was generally unreliable for assessing obstruction.
