Key result
In elderly patients undergoing mitral valvotomy, the pre-operative diastolic murmur disappeared in 67.2% of cases with a final valve size of ≥4 cm compared to 10.9% of those with a size <4 cm.
Why the study?
Does the final valve size achieved during mitral valvotomy affect the disappearance of the mitral diastolic murmur in elderly patients with rheumatic mitral valve disease?

Larger valve size may associate with murmur abolition in this case report; leaves open clinical relevance and need for prospective validation.

Does the final valve size achieved during mitral valvotomy affect the disappearance of the mitral diastolic murmur in elderly patients with rheumatic mitral valve disease?
Absolute Event Rate: 67.2% vs 10.9%
Achieving a larger final valve size (≥4 cm) during mitral valvotomy significantly increases the likelihood of abolishing the mitral diastolic murmur.
T. B. Hargreaves (1961) conducted an observational in Rheumatic Mitral Valve Disease (n=210). Mitral valvotomy with final valve size ≥4 cm vs. Final valve size <4 cm was evaluated on Disappearance of pre-operative diastolic murmur. In elderly patients undergoing mitral valvotomy, the pre-operative diastolic murmur disappeared in 67.2% of cases with a final valve size of ≥4 cm compared to 10.9% of those with a size <4 cm.
